JMeter scripts for continuous integration

2010-03-09T11:48:00.001+02:00

A client needed to move from Oracle to Microsoft Sql Server and wanted to make sure MS sql server will work as fast as Oracle does.

We used JMeter to record various scenarios from our web application for benchmarking against two different databases.

After tuning sql server a bit we have seen dramatic performance improvements and by re-running our recorded tests we could keep track of our progress.

Jmeter scripts can be executed from ant and maven builds. It is very good idea to run jmeter scripts as part of continuous integration process at least once a day.

JMeter allows inserting assertions against the response you get back from server by regular expression matching. So in theory scripts can verify json, xml responses. As a result, you can position those scripts as integration tests as well as performance tests.

Hudson has a performance plugin that can execute jmeter tests and report performance and robustness trend of the application.

This way you can measure performance trends of stable development environments (e.g pre-production servers) as development patches are applied to them.

One easy way to record web application interaction and place assertions against html responses is to use Badboy.
BadBoy is an capture/replay interface which can export as jmeter scripts.

There are many ways to test/benchmark request-response exchange, this is just one of them. What other tools & techniques do you use to track performance and stability trend of web applications?

Code Katas

2010-02-25T17:26:00.001+02:00

A Code Kata is an exercise in writing code preferably in test driven way, which you do repeat periodically.

There are very good examples of them around the Internet.

It generally takes 15 to 20 minutes to finish for the first time, after a few cycles duration goes down by almost by half .

Every time I repeat , I find new shortcuts in my development environment and a few things to do differently.

Here are some of my favorites.

http://codekata.pragprog.com/2007/01/code_kata_one_s.html

http://codingkata.org/katas/unit/towers-hanoi

I prefer Java but intend to write some of them in Scala Ruby and Groovy.

Virtual development environments

2010-02-17T16:10:00.001+02:00

Using virtual machines to maintain development environments ( development ide to application server config) is becoming a common practice.
8-core cpus, 4+ gb rams and 64 bit operating systems allow running guest operating systems without a lot of performance penalties.

What should be in a baseline image?

Notepad alternative
Continuous integration server running unit tests of your project (e.g Hudson)
IDE (Eclipse or Netbeans) and plugins
Static code analyzers with customized ruleset of your team (integrated with IDE) e.g PMD, FindBugs
Application server (integrated with IDE) (Glassfish)
Database server with initial data loaded.
Load generator with sample scenarios (e.g Apache Jmeter)
Cache server (memcached)
Any other frameworks your project needs (e.g Grails)
SQL client (depends on your db)
Source control client (SVN or git client)

There are a lot of advantages
1- Common virtual machine image to get new members of team running up in short time.
2- No need to change settings between clients and projects

For virtualization, I prefer VirtualBox. Vmware is another alternative and so is Parallels in Mac OS X.

What other tools do you install as baseline for virtual systems?

Single responsibility principle

2010-02-16T17:22:00.001+02:00

Single responsibility principle

Recently i needed to compile our all jasper-report files during application start-up.
I was modifying existing code-base to enable precompiling xml reports to binary .jreport files.

It was simple enough, traverse all *.jrxml files at a certain directory and use net.sf.jasperreports.engine.JasperCompileManager to do the actual compiling.

Here is how i traversed all files under a directory.

    private void visitAllFiles(File dir)  {
        if (dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < children.length; i++) {
                visitAllFiles(new File(dir, children[i]));
            }
        } else {
            //doSomething();
       }   
}

Here is what is wrong with this version.

The infrastructure logic to traverse the files and business logic to compile reports resides in same class.

If i needed traverse files for something else (for example to backup old compiled reports) i would need to duplicate infrastructure logic.

It seems this class is trying to do too many things. I separated this class to a reusable FileCrawler and FileVisitor.

public interface FileVisitor {
    void visit(File fileToProcess) ;
}

FileCrawler takes a visitor and calls visit method for each file it encounters.

     
    public FileCrawler(final File root, final FileVisitor visitor) {
       this.visitor = visitor;
    }

    private void visitAllFiles(File dir)  {
        if (dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < children.length; i++) {
                visitAllFiles(new File(dir, children[i]));
            }
        } else {
            visitor.visit(dir);
        }
    }

Usage is as follows:

  new FileCrawler(new File(this.cacheFilePath), new ReportCompiler()).start();

ReportCompiler implements FileVisitor and looks like as follows:

public void visit(File fileToProcess)  {
        String name = fileToProcess.getName();
        if (name.endsWith(".jrxml")){
            compileReport(fileToProcess.getParent(),name);
        }
}

Now i can use anonymous inner classes to create simple reusable directory traversing logic.

new FileCrawler (new File (root), new FileVisitor() {
            public void visit(File fileToProcess) {
                String name = fileToProcess.getName();
                if (name.endsWith(".jreport")){
                    fileToProcess.delete();
                }
            }
        });

stackoverflow clones

2009-11-09T14:51:00.004+02:00

After the success of stackoverflow, many applications with similar concepts have emerged.
while some of the chinese sites have even used the same design, some of the web applications are geniune attempts to add value.
O'Reilly with its vast knowledge base of everything related computers is trying to take advantage of it with O'Reilly Answers concept.

What other sites do you see as a stackoverflow competitor?

Update here is once stackoverflow wanna be in Turkish

Distributed Processing

2009-11-04T15:52:00.004+02:00

Processing log data and extracting valuable insight from it will not be straightforward. Fortunately there are a few pointers to help.

1- Commonj Work manager API
CommonJ is a BEA and IBM joint specification that provides a standard for executing concurrent tasks in a JEE environment. It has support for the Master/Worker pattern in its WorkManager API. It has open source implementations too.

2- Master-worker pattern can be easily distributed with Terracota infrastructure.

High Performance XML Processing

2009-11-03T19:09:00.002+02:00

In my current project we will probably need hardware XML accelerator to process many millions of xml messages..
There is an ongoing EU project in which Cybersoft participates.
IBM can supply the hardware XML processor via DataPower

system.out.println

2009-11-03T13:51:00.002+02:00

Note to myself:
You should never use System.out.println in production code.. See the synchronized block out there.


public void println(String x) {
   synchronized (this) {
     print(x);
     newLine();
   }
}

Back to Cybersoft

2009-10-31T13:25:00.002+02:00

Last week i switched back to my old company from Turkcell to Cybersoft.
This was part of a strategic decision to move to banking domain field.
My first task is to create a centralized audit log management system.
Our aim is to do fraud detection in real time by analyzing data coming from different layers of system (client/server/db)
BDDK (the regulator of the banking system) also enforces such a system to be in place well before 2012.
Performance and scalability challenges ahead, really interesting times indeed..

Grails

2009-10-30T16:16:00.000+02:00

I am using Grails since 1.0 release.
After being acquired by SpringSource, the future is looking bright for the framework.
It has a great plugin community.
Unfortunately there are almost no Turkish documentation on it.
In the near future i will launch a series of tutorials on Groovy/grails in Turkish.

One-JAR

2007-09-11T13:27:00.000+03:00

A friend asked if he could produce a single jar file with all required libraries packed inside it.
One-Jar does a good job of it.
It is easy to work with it from Eclipse too, thanks to Fat Jar plugin.

Managing user expectations

2007-07-17T00:29:00.000+03:00

Managing user expectations is really important skill at every level of your career.

At the beginning of a career, you will most likely to answer the ultimate question of
"How long will it take this to finish ?" type of questions. Your manager will ask this to you.

Later as a consultant you will need to answer same question to clients, or as a manager you will need to come up with an answer for your senior manager.

As an entrepreneur you will need to answer this crucial question for cost estimation and bidding.

How long will it take? and by what percent will it be finished?
Should i put an beta version out and improve it as customers use it?
or wait for an stable 1.0 release?

At the root of all these questions lies the expectation management.

Here are some tips i have been employing when i need to answer how long it will take?

Try to judge from previous similar experience, if you wrote down your previous work allocation via time sheets on the average you know how long it will take
Do a quick POC type development which will not take more than a few days if possible
Do prototyping of important use cases and features, (important being defined by the customer) and try to estimate from that knowledge
If there are external stakeholders you can't control, estimate with relativity of their work. i.e It should take no more than a week, after we receive design templates from XYZ.
If possible, Slice the project to little periods, try to keep quality, time constant and vary the features. i.e We will work on these features for a month. We may not finish all features but we will keep our quality metrics to this level. If you are not satisfied with our work, you can always cancel the contract.

Note that the last strategy is not for fixed price projects. But it works because contractor will work honest to get the remaining big portion of the project. It shields the bidder from excessive unpaid change requests. And you can morph to fixed price later, after unknowns are eliminated.

Also last one has the nice feature of "fail fast". If a project is doomed to fail, it will fail in the first one little slice..

And during project implementation:

Don't present the work you are doing as too easy or too hard. In other words, communicate clearly.
Don't ever demo a feature complete UI early, because users will expect much more complex screens at the end. This is physiological. Instead show some cool features and build some excitement.
Always safe estimate a little more than it will take, this way you will always finish before time and earn some credits.
Never overestimate with a huge margin, next time they will not believe and your estimations will be halved by customer or manager. You will lose credibility once and for all.

What are your suggestions for estimating how long it will take?

Accessing dotted attributes from JSTL EL

2007-07-16T22:20:00.000+03:00

One of my friends was in trouble with accessing scope attributes from JSTL expression language.
He wanted to use <c:out value="${myDomain.myObject}"></c:out>, to access an object under the key of "myDomain.myObject"

EL tries to retrieve an object under the myDomain key and then tries to invoke getMyObject() on that object. Obviously that wasnt working.

There is no standart way of accessing such attributes. But if you know which scope your object lives in, you can access like this.


 <c:out value="${sessionScope['myDomain.myObject']}" />

A while ago Gavin King blogged about his EE6 wishlist, i add this one to my wishlist...

Using the right DOCTYPE

2007-07-16T16:03:00.000+03:00

I have been busy updating the look and feel of an extra-net application.
I was using corporate id guidelines, so it wasn't a very creative process at all.
I have tried to use CSS as much as possible without resorting to tables for layout.

Apparently declaring doctypes is very important for all CSS/layout configuration to work properly.

Form design with CSS

2007-07-11T20:10:00.000+03:00

I say enough to table based form designs. It is quite shocking to learn that you have to do lots of hacks to get form elements aligned properly across all browsers.
Still the outcome is beatiful.

5 tools you can't live without

2007-07-11T13:56:00.000+03:00

Lately I am doing some web application restyling, cssing. I find myself using more and more of these tools.

There are some more useful utilities in the link i have included.

Technical debt

2007-06-29T01:35:00.000+03:00

Lately i am paying some technical debts in a project about to go live in a few weeks.
I can easily spot hacked code by following below placeholders.
//FIXME: Some explanation
//TODO: Optimize here if possible
//TEST: Test this condition with respect to x and y.

Functional test reports often point to unreliable piece of code too. Using a bug tracker really helps.

Checked or unchecked exceptions

2007-06-28T21:33:00.000+03:00

Every Java developer at one point in her career needs to decide how to convey an exception/error to other layers of application.

Hopefully someone in her organization clearly communicated how exceptions should be handled to her. This is one of the important duties of enterprise architects, mentors, senior developers.

Some would argue that checked exceptions have no place in code, while others argue that there is a place for them.

I find the following piece very informative and balanced.

Here are some key things i hold dear:

1- Differentiate between fault and contingencies. Represent faults with unchecked exceptions.
"Can not connect to server" type errors fall in the category of faults.

2- Try to minimize the use of checked exceptions especially if you are developing an API that will be used by lots of modules/components. Checked exceptions are viral and tend to pollute codebase with unnecessary trycatchfinally blocks.
Remember that you can use try finally block without catching anything in between...
Often times there are other ways of doing it too.

For example following fictitious method throws InSufficientBalanceException if payment amount is larger than account balance.
doPay(Payment p) throws InSufficientBalanceException()

Clients of this method will catch the exception and try to recover from it later.

A much more clean design would be like this.
------
boolean isBalanceEnough(Payment p)
doPay(Payment p) // throws unchecked exception
------

Above API needs to be used in a disciplined strict way. (API is based on a contract.)
------
if(! isBalanceEnough(p)){
// transfer some money from other account
}
doPay(p)
------
Unit tests, code inspections/reviews are expected to spot any misuse of API. Better yet "design by contract" is emerging in Java realm with the advent of annotations.
Then the method signature will look like this.

@pre("isBalanceEnough(p)")
public void doPay(Payment p)

3- Dont try to shape program flow with exceptions. Exceptions should be exceptional.
Especially input validation shall not be done with exceptions. Because users are expected to put bad input almost regularly and throwing exception on first invalid input is bad practice. Instead collect all validation results and display them at once.

4- Dont ever swallow exceptions without doiny anything.

try{
// do something
}catch(Throwable t){}

Above code will swallow unchecked exceptions too! Welcome to the endless sessions of debugging!!

What are your guidelines for dealing with exceptions and errors in your programs?

Google browser sync

2007-06-28T13:41:00.000+03:00

Google browser sync is a Firefox plug-in that continuously synchronizes your browser settings – including bookmarks, history, persistent cookies. Great solution if you are using different computers at work and at home..

Even if you only use single computer, you can use it to backup your browser settings and to restore your open tabs and windows across browser sessions..

A3 process - collaborative, in-depth problem-solving

2007-06-28T01:17:00.000+03:00

I have seen A3 process in action.

This one sheet of paper does a lot to tell about the problem/opportunity to all stakeholders.

Don't get me wrong, preparing this little piece of paper is a result of hard work long meetings and careful planning. Yet it is simple, visual and concise.

Here is a template for your consideration.

Enterprise Architects - where do they belong?

2007-06-28T00:48:00.000+03:00

Setting up a solid enterprise architecture is pretty important if the company has more than a few of projects under implementation.

With a moving target like programming languages, virtual machine versions, database tools it is important to provide developer teams a solid guide of whats acceptable whats not..

The problem is where do we deploy e.a architects so that they are most efficient and useful?

This article debates that they should be a part of development team.

From my own experience a senior architect or an enterprise architect is best utilized in the proof-of-concept phase of a project. Some would call this period a spike, a phase in which elements of architecture is used in conjunction to minimize surprises later on..

Later as development progresses recurring jobs should be scheduled for architects so that they can monitor/audit the development progress regularly. (Say once a week)

This way an architect could shepherd two or three projects with ease and still can do research and paper work to document best practices and strategies. Besides cross-pollination between projects is very valuable, lessons learnt from one project can be applied to another..

I am not against forming a pool of architects with their own managers etc, just don't let them build their own ivory towers, keep them close to battle-front of development.

One last note, it is a dream come true if at least one senior developer in the team is on par with architects skills and experience..

The most succesful language of web

2007-06-27T03:18:00.000+03:00

A while ago, i have claimed that javascript was the most successful ubiquitous language of web.
It seems that the fourth edition of ECMA-Scriptwill make sure it stays like that for the foreseeable future.

Here are some highlights of the upcoming version. (From Wikipedia)

Classes
Packages and namespaces
Optional static typing
Generators and iterators
Destructuring assignment (likely)
JSON Encoding/Decoding

I don't see Javascript as a threat to Java language or JVM platform, in fact both languages can collaborate happily if the need arises. In fact thats why Javascript was written in the first place.

javascript and unit tests

2007-06-27T02:50:00.000+03:00

With dynamic typed languages, things can go wrong after a few refactorings due to lack of extra information that is available with static typed languages.

Unit/integration tests are expected to cover this front for these languages. It shouldn't be coincidence that the rise of dynamic languages are in parallel with the rise of test driven development/continuous integration (agile/lean)

Two approaches come to mind.

Selenium like tests ( scenario based kinda integration tests)
JsUnit like tests (kinda unit tests)

Traditionally JS testing/debugging was left to alert statements and lots of retries, however i find myself using firebug regularly to inspect and analyze my javascript codes.

Here you can watch the creator of it going through most useful features of it.

InfoQ - must follow site...

2007-06-26T01:07:00.000+03:00

InfoQ does a good job of highlighting interesting topics, posts from blogosphere.
Here is one example, notice how they add value to story by mentioning
the Apache Lucene Hadoop subproject (which contains an implementation of MapReduce and a HDFS, a GFS-like distributed file system)

YUI and javascript

2007-06-25T03:00:00.000+03:00

If you are developing intranet applications you may not feel the heat of cross-browser compatibility, however once you have started working on a world facing web application you have to know and apply lots of details for each browser out there.

Luckily YUI is there for us to help..

Personally i like handpicking javascript code for websites, so you-write-in-your-comfortable-java editor-and-we-will-turn-it-into-javascript approach is no good for me.. (e.g gwt)

YUI helps with CSS, fonts, layout (grids)

And it doesnt stop there, it also gives some components, animations, transitions.. All designed by smart yahoo developers and they actually use it in their own products..

It is low-level (yet functional), extensible and enforcing best practices all along the way.. It is a great start to learn Javascript

Games can be coded in it..

Yahoo provides a set of design patterns as companion too.

With their new CEOs at helm, i would say keeping in touch with developer community with such warm relations can only be a good sign of things to come.

Even google uses it. Nuff said.

The art of innovation.. Lessons from Apple..

2007-06-23T13:10:00.000+03:00

Economist is a higly regarded magazine for me. More on topics of technology, finance and less of world affairs..
Anyway the article l am referring to tells about the key ingredients of Apples' success.

1- Innovation can come from without as well as within.
Remember that Mac OS X is based on the Mach kernel and is derived from the BSD implementation of Unix in NEXTSTEP..

2- Design new products around the needs of the user, not the demands of the technology. Strive for simplicity...

3- Set the trends yourself, keeping user needs and simplicity in mind. Ignore what market analysts, staticians say for a minute..

4- Fail wisely, learn from past mistakes ..
e.g Music phone developed in conjuction with Motorola failed, iPhone is designed with lessons learnt.

-----
The art of software development can learn alot from the above principles.
Finding the sweet spot of usability/simplicity with complex requirements/workflows is one thing.

Resisting to use the latest/greatest technology for the sake of using one is one thing.(Remember AJAX?)

Short, faster delivery cycles and risk management is one thing (to fail early and wisely)
Lean development practices tell alot about it.

But as a last usual remark talk is cheap, walking the walk is different than talking the walk..
If it wasnt so, we would be seeing more Apples, 37signals, interface21s around us..

P6Spy to the rescue

2007-06-19T11:08:00.000+03:00

If you ever find yourself trying to use a *reusable* component that is half assed documented, you could attack the problem in many ways.

1- Run unit tests (unit tests tell much more than shit amount of documentation)
2- Read javadoc
3- Inspect database /E-R diagram
4- Endless hours of debugs (assuming you have access to source code)
etc etc

For item 3/4, i highly recommend using P6Spy to log each sql statement. Hibernate/iBatis also has a way of logging sql statements issued. P6Spy proxies jdbc driver and hands over to real driver after logging it to file.

Today i found myself deciphering a DB2 SQLJ based component. JAD is also handy too.

Configuring log4j within a Spring env.

2007-06-14T14:14:00.000+03:00

Configuring log4j in a web environment is easy. See this and this
However Spring provides no-outof box configuration class. Log4jConfigurer is abstract..

Here is a simple class that initialize log4j for a standalone application.


public class ConcreteLog4jConfigurer extends Log4jConfigurer {
private String location;

public void init() throws Exception {
 initLogging(location);
}


public void destroy() throws Exception {
 shutdownLogging();
}


/**
 * @return the location
 */
public String getLocation() {
 return location;
}


/**
 * @param location the location to set
 */
public void setLocation(String location) {
 this.location = location;
}


}

The trick is to configure this class with an init-method and destroy-method.


bean id="concreteLog4jConfigurer" class="ConcreteLog4jConfigurer" method="init"
    property name="location"
       value classpath:myLog4J.properties /value
    /property
/bean

There are other properties like refresh period etc, that can be exposed too. That is left as an exercise to readers -:)

crimson vs xerces

2007-06-13T14:16:00.000+03:00

We use iBatis + spring in our projects..
When i tried to launch a testcase in one of our new projects a strange error happened.

SAXParseException: Document root element is missing

Crimson parser that comes default with jdk1.4 is the reason behind it.
jdk1.5 and xerces parses same xml documents fine.
A google search reveals that i am not alone too..

Edit: The root cause was that spring xml was encoded in UTF-8 with high BOM.
When i manually converted documents encoding to US-ASCII (properties->encoding)
three strange characters revealed themselves at the very beginning of file. Deleting them solved the problem. Lesson learned: Sun's Crimson parser does not support BOM markers.

The most succesful programming language of web

2007-06-12T00:02:00.000+03:00

Javascript is the ultimate winner. It is not the most elegant programming language for sure, it has many quirks and bad parts. However it was at the right place at the right time.
It is everywhere
1- browsers (lots of browsers)
2- desktop widgets ala yahoo and apple
3- on your phone Apple iPhone will only support javascript/css combo.

It has some very interesting good parts as outlined by the Douglas Crockford of JSON fame.

As pointed by Mr. Crockford, i am also learning mostly from trials and errors, but that is about to change. Javascript is just not for form validation in my eyes now.

By the way the verifier he talks about can be found here.

SchemaSpy

2007-06-02T12:54:00.000+03:00

SchemaSpy can examine a whole database and visualize entity relations. Very nice work.
-----------------------
Do you hate starting on a new project and having to try to figure out someone else's idea of a database? Or are you in QA and the developers expect you to understand all the relationships in their schema? If so then this tool's for you..
-----------------------

Also this week i focus on Struts2 , i started with maven2 archetype and got a working eclipse project in seconds...

I like the way struts2 is open to third party innovation via its plugin architecture

After holiday

2006-10-26T11:29:00.000+03:00

Our holiday was so well placed, all of the team needed it. We have finished analysis and design phase of our international project very successfully.
It was finished the last day before the national holiday. Very good timing indeed.

After holiday, we are ready to tackle construction phase. One thing i would like to mention, we opted to use Jetty server to do quick development.(See jetty launcher) So far, we are very happy with it.

On holiday, i visited a nice village, got some fresh air and relaxed. i visited relatives and it was refreshing.

French colonisation is good for all of us

2006-10-13T19:48:00.000+03:00

So French would require schools to stress the "positive role" of French colonialism.
You bet!!
-------------

France on Tuesday played down a stinging attack by Algerian President Abdelaziz Bouteflika, after he repeated claims that France's colonisation of the north African country had been "genocidal".

The foreign ministry in Paris said it saw Bouteflika's comments, made on Monday on the 61st anniversary of a massacre of Algerian civilians by French troops, as leaving room for cooperation.

"We understand, from these statements, that there is a shared will to move forward and to strengthen bilateral relations," said ministry spokesman Denis Simonneau.

In a declaration read at the site of the massacre in Guelma, eastern Algeria, Bouteflika described France's colonisation of his country, which it ruled from 1830 to 1962, as "long, brutal, genocidal".

Algeria, he said, had a "fundamental right" to a "public and solemn apology for the crime of colonisation committed againist our people".

The Algerian leader dismissed suggestions of a "crisis" between Paris and Algiers, but said there was "still much to do in order to fulfil our shared ambition to go further together".

The French foreign ministry declined to comment on Bouteflika's use of the word "genocidal".

Bouteflika raised tensions last month by declaring that colonial France had committed a "genocide of Algerian identity".

Relations between France and Algeria have been strained since February 2005 when the French government passed a law - later repealed - requiring schools to stress the "positive role" of French colonialism.

Plans for a "friendship treaty" between the two countries have been shelved indefinitely.

French humour

2006-10-13T19:24:00.000+03:00

The question is that the French have jokes, but do they have a sense of humour?

apparently NO. After their joking with history and historians i am sure they have a dry sense of humour.

A handful of politicians after Armenian diaspora support is playing dangerous games.
French should know better that when a civil war starts, innocent people can get killed.
After all French legionners(whatever it is spelled) fueled lots of war in Africa.
With their dirty hands from Algeria and etal they are the last nation to tell us our history.

The silly side of thing is that French would punish anyone denying Armenians are victims of genocide. Not even academicians.. So french politicians decided it for everyone. full period.

Let the history reveal itself.

Amazon EC2

2006-08-24T12:56:00.000+03:00

Amazon Web services divison is making interesting product releases.
After Amazon S3(Simple Storage Service), Amazon SQS (Simple Queue Service)
the company released Amazon EC2.
Basically it is a virtual server hosted for you in the amazon cloud. You pay for the instance hours and bandwidth that you actually consume. Integrating with SQS and S3 it provides an compelling alternative to managing your own petty infrastructure.

Winning the mindshare of developers should be the next logical step. I want my free developer account and some nice tutorials to get me started with in Java or some decent scripting language.

RCP

2006-06-27T02:43:00.000+03:00

Currently i am getting my feet wet with rich client projects like Eclipse RCP, Spring RCP.
Currently working with a closed-source RCP in my day job, i have high standards.
I expect:
drag and drop visual editor.
role based authorized menu system.
a standard way to achieve remoting(XML-RPC, web services)
solid navigation support.

Spring RCP is strong in the services layer and Eclipse on the visual side. I want the best of both worlds. Dependency injection can be the solution for the middle-tier, but i am not sure it can be used effectively for building complex user interfaces.

Eclipse RCP has one downside and it is SWT. I believe Swing is superior in terms of maintainability, interoperability. Netbeans is playing catch-up for sometime. It has one curse and it is SUN itself.

Why do we struggle to do lots of things in browsers quirky HTML/CSS support.

Lets realize that deployment will be less of an issue with broadband access rising.

Standarting on Eclipse RCP sounds more and more advantegous for large multinational companies. Imagine using a Eclipse client with two plugins that are developed by Human Resources department in US and portal team in Turkey.

The key to successfully adopting RCP is churning out applications much more quickier than html development.

Some of the interesting advantages are:
Supporting occasionally connected clients, (Rich client can do that so easily)
Transaction support (Spring can do transaction management for you)
Grid computing (embed Jetty in the client and listen for work requests from the dispatcher)
Document and office integration.

Some of the applications lend themselves to rich clients much more better than others.

A development shop should define
local caching strategy, (cache reference data on the client (eh-cache))
page composition strategy,(visual and reusable widgets)
action handling strategy, decoupling from UI(web services, hessian burlap?)
deployment strategy (web start, update center)

If your company or team needs to work on a project that calls for a rich client user interface development, just shout!

when the need arises i can manage and run projects that involve Spring-core, Spring MVC , struts sitemesh and Ajax(DWR)....

After holiday

2005-11-17T14:46:00.000+02:00

Just returned from holiday. Our international project will start at September 1/2006.

It will be an interesting project that will facilitate Agile software methodology(sort of lean and scrum)

I believe identifying and removing waste from software development processes is really challenging and sometimes error-prone. At least we will apply lessons learned from previous mistakes.

We expect to do daily review meetings and tracking to determine earned value/effort.

All in all i am excited that i have a lot to learn from that experience.

Ajax

2005-08-21T20:53:00.000+03:00

It seems that AJAX will be the big thing for 2005-06.
Web services concept was, in my opinion, a general without a soldier for the UI front. AJAX requires a solid XML processing infrastructure and provides responsive user interfaces.
AJAX will nicely compliment web services infrastructure and be used together. (See how XForms are being implemented server side, which was impossible before AJAX era.)

Microsoft and all other big players are aligning behind it. Enterprise Java specs will make AJAX a core feature of JSF implementations. I am asking some browser vendors to call to arms.

From now any serious intranet application should be built on AJAX techniques, provided that browser can be pinned down to major version number. Google effect is pushing the limits and setting the standarts.

Married!!

2005-07-31T18:19:00.000+03:00

From 9Th of July i am a married geek. Honeymoon was in Cyprus, it is a wonderful place neglected by the world. For a week We visited many wonderful shores of Turkish side of the island. I had the opportunity to listen to my inner voice.

Now i believe i have to devote more time to open source projects and be more vocal about open source adoption in my current company.

Marriage is going fantastic, we are learning to cook traditional Turkish meals and enjoying Istanbul. I love her so much.

New Projects

2005-02-23T09:38:00.000+02:00

Moving to new projects.. I will be building lots of user interface development, using in-house developed XML based toolkit. Then a renderer will translate it to Java Swing. I will be writing rules and actions encoded in XML format. I hope to apply user interface design principles and be consistent over all. The project is massive, at least 40 developers will be working on it. My team is 5-6 skilled developers, hopefully we will build on consistency from day 1.

A new year, fresh hopes.. new dynamism.. whatever i do i want to do with passion and care, both in software development and in my social life.
success and happiness comes through passion and love..

happy new year all, hope 2005 would be a better year than 2004.

Are you having fun while you work?

2004-12-18T15:05:00.000+02:00

Yep i do. i love sensing that the software i build saves time and generate value..
While developing software i not only cover the basics of the business process but try to simplify, clarify it.

by sometimes asking (not so) dumb questions, i try to understand why things are done the way it is.

Occaisonally there are things to improve and optimise. The challenge ahead of me is to improvise the usability of a web application
managing a complex workflow for automative industry.

Building a new model, negotiating timings with part suppliers is such a complex job. The specialists will virtually use our product all day and i want them to go home happy not frustrated..

Google is nowadays setting the standarts for the usability. The technique used is not fairly new.

Implementing it cross-browser style is the hard part and brilliant enginneers of Google managed it by providing a cookie backed-frame reloading scheme for old browsers.

Expect to see people frameworking and easing the pain in months to come. Simply the bar is raised to never come back down again.
PS: i was suprised to learn that Opera 7.x falls into old browser category for the lack of XmlHttpRequest

Prevayler

2004-09-18T13:26:00.000+03:00

i need to be able to save the snapshot of our plc integration system,
however i cant really anticipate what exactly i need to save. so i opted for saving a java object as BLOB object and updating it as necessary. unfortunately as fields are added to it, serialization schema complains. perhaps i will store attributes as a hashmap and be done with it. Then came Prevayler to my attention, why on earth do i come by elegant solutions after tackling problems?

Using Prevayler will be a risk, because our system will heavily use SQL for reporting. No one gets fired for sticking to Oracle and SQL.

AVK

2004-09-17T18:28:00.000+03:00

Lately i am consulting for a web application project that needs to be deployed on IBM OS/390 Websphere 5.0. Database is also on same OS(DB2 v7). First it took them a long time to define a simple datasource properly. Secondly they did a bad job of migrating our test database to production database. The database encoding they used is Cp1026 (IBM LATIN5), needless to say i opted for UTF-8 during development. Well to keep a long story short this weekend i have to modify the data access layer to do encoding conversion as it reads and writes. thanks to our flexible DAO layer, i need to edit a single class. i miss unit testing in those cases.
i will also use SUN's Application Verification Kit to validate the project to keep IBM's mouth shut.
A busy weekend awaits me.

Java Tiger

2004-09-17T18:09:00.000+03:00

Lately i have been toying with Tiger's new features. Autoboxing is cool for sure, and generics can be useful at times. For a developer never written in C++, i learnt to live without it.
Really using MVC, and interface based programming i am quiet happy. For me the major improvements are the Swing /performance improvements. Rich client space will be the next battlefield of .NET and Java. Armed with Longhorn buzz and enjoying Windows integration .NET is close to finish. However healthy competition in Java space could push up.
What is more, for me desktop is shifting towards cellphone monitors, J2ME is running well ahead there.
Anyway XML based GUI definitions are the way go. Then specific renderers can be written to output to html, swing or .NET who knows. Swings MVC paradigm fits into stateless HTML pages so well. Web applications tend to keep state information on server(sessions), Swing lets the same with model objects. At least the way it should be done is so. The only gap is event handling, and JSF nicely bridges there with its component oriented architecture.

Well here are my random thoughts at the end of a week.
This weekend i will be coding to integrate a web app with production line controller.
i hope to investigate JasperReports and WebWork 2.1.

information management

2004-09-17T16:22:00.000+03:00

After my laptop is broken, i lost many bits of precious information(links contacts tips and tricks i have collected over time)
i always thought Confluence like tools would save me big time.
Today i seen onfolio, an information management tool. i need such a tool. even imagining developing a fraction of a such a tool is fantastic. open source alternatives are more than welcome.

Gmail

2004-09-17T16:18:00.000+03:00

i got my gmail account with an invitation from a friend.
unfortunately my preferred username was already taken, so i had to go with uysal.kara@. i can live with that. The user interface is pretty slick and javascript is all over the place.
made me wish i had the time and patience to learn about javascript in deep.

Incremental prototyping

2004-08-23T20:53:00.000+03:00

At the dawn of the second Toyota project we are looking to strengthen our reporting side. For the second project, Jasper Reports will be integrated and we will present reports as pdf files.
Also we will use incremental prototyping. we will agree upon two-three weeks of screens on prototypes and move forward.

Model driven development

2004-08-13T13:50:00.000+03:00

For big projects model driven development can be needed, but when a small project comes up it is probably better to keep paperwork minimum and delve into prototyping(assuming you have a framework to build upon). Generally a well studied use-case and activity diagrams of a few key scenarios and state diagram of a few key entities would suffice. Key to success is test driven development i believe. For me any project scope larger than 6 months is doomed to fail. Even a big project can be scheduled to give fruits in 6 months cycle.

JSF is hot

Storyboard and Prototyping

2004-07-28T20:44:00.000+03:00

For our next project at Toyota we will do storyboarding as the use-case diagrams are being fleshed out with all interested parties.
Two software is promising:

Axure

I am also determined to use StrutsTestCase and Hibernate this time.

Migration

2004-07-14T22:28:00.000+03:00

At Toyota, migrating to new system is fun and challenging.

You need to have excel skills as well as a good understanding of new java regexp package,

the other system i helped designed is deployed on a OS/390 websphere, no actually ibm couldnt manage it..

i hope they can install SunJCE to that machine when we ask them to. Cause we are informed that EAR file we have given is undergoing through an instruction code manipılation before it is deployed.

i also hope that reflection which is at the heart of any serious java framework these days wont be broken by the transformation. i am not asking too much am i?
they wouldnt call it java compatible would they ?

A hardware mulfunction

2004-05-24T11:05:00.000+03:00

costs us half a day. It was a DB2 living on machine, no backups as it was setup at the weekend. Electricity is the suspected. Things are going slower than i want.

Todays recipe:

2004-05-22T12:11:00.000+03:00

Apache Commons HttpClient,
configure it work with session management,
configure it work thru SSL.
We are on a tight schedule. Basically i want to mail a stateful page as html.
The only way i can think of is read the page like a stranger. Does servlet api let you collect a execution result and use it? i dont think so, not without hacking anyway.. i dont have that time and luxury.

Here we go !

2004-04-28T19:05:00.000+03:00

I am helping build a struts based web application these days, and support for Struts at IBM tools(WSAD) is pretty good. Add Struts Unit Tests to the equation we have a solid ground for development.
For Model objects standard JUnit will suffice.
For templating support we use tiles which integrates with Struts so well

After a long time i am back with news

I am working for Cybersoft for a while..

I've got a new car now.

The work is great learning experience..
Cybersoft has a great reputation and experience of doing software development.. Established standards makes great software.

Right now i a trying to figure out best practices for wiring web applications with Struts-Tiles, and our own Persistence Model.

The company uses a closed framework called Aurora, to create Rich internet applications, based on XML definitions and service orientec architecture.. so JSP/HTML front end is relatively new and unexplored area which i pioneer.

That's all folks for now.. I will not keep this blog hungry.. i promise to myself..
