Software Engineering
Automatic testing Oracle Service Bus using Jenkins, maven and SoapUI
A lot of current projects are implementing some sort of service based architecture. Testing in this architecture becomes more complex. When implementing an OSB project with Scrum you test-automation is imperative. Scrum will require more frequent testing of your system. This is only feasible (in time and money) when you […]

IETester: Develop and test your site for multiple versions of Internet Explorer
When developing or testing your web application, you often have to support different browsers and versions. On Window machines testing for different versions of Firefox, Opera and Chrome is not a real problem as these browsers all allow you to install different versions on one machine. Only Internet Explorer (IE) […]

Project Estimation & Control based on Use Cases
This week Sander Hoogendoorn (Cap Gemini) presented a seminar about “Estimation with Use Casesâ€. Generally, this seminar confirmed that the development method of AMIS, internally called the “Way We Work @AMIS†is still valid and up-to-date. However, there are some interesting things to learn from this seminar. The three most […]
Mapping composite primary keys in JPA How to work around a bug in Hibernate Annotations
A table without single-column primary key, Java developers don’t like them because it’s more work than just putting @Id on a field. When you’re using Hibernate Annotations you might also run into an annoying bug. In this article I will explain how to map a composite primary key with JPA-annotations […]
JavaOne 2008 LAB: Dynamic Service Composition with OpenESB and NetBeans
Apart from sessions in which an overview of a certain topic is presented, JavaOne also had a few sessions in which the audience got the chance to actually do some work theirselves. These so called labs typically took up two hours in contrast to "normal" sessions that took up one […]
Subversion 1.5 Presentation at JavaOne
That Subversion is popular among Java programmers is no big surprise. If it needed proof, the huge line of people waiting to get into the “Subversion 1.5: Great New Functionality For Developers” session at the first day of JavaOne 2008 would have provided it. In a 50 minute session, the […]

Automated SOAP testing with maven and the SoapUI plugin
Currently there are few tools that can support testing SOAP interfaces. Both Jmeter and SoapUI are suited for testing soap interfaces. SoapUI is explicitly created for testing SOAP interfaces and Jmeter has a SOAP support since version 2.3.x. I have worked with both tools and I prefer SoapUI. It has […]

Maven based configuration management with automatic build number
An important questions in software deployment and testing is “What is the version of the software I am looking at”. It is frustrating for a tester or an end user not knowing if the planned upgrade is performed or not. Having a solid version numbering policy is a solution to […]
How to Unit-test private methods
I know it’s kind of wrong to test private methods and there are a lot of articles and books that will explain you why. But sometimes you have an old code base where you have to unit-test some private methods to speed up development time. Today I got such a […]
Oracle SOA Suite: further Build and Deployment Automation for Enterprise Service Bus components
Some time ago I wrote an article on SOA Suite Build, Deployment and Test Automation. A section of the article was devoted to automating builds and deployments for Oracle Enterprise Service Bus (ESB) components. Not covered was deployment of Services to multiple environments as is usually done throughout the development […]
Maven JMeter plugin and report generation (the last steps to get it working)
JMeter (http://jakarta.apache.org/jmeter/)is a powerful tool for functional and performance testing web applications. JMeter, opposed to selenium, also works perfectly on generated applications (like Oracle ADF ). One of the key strengths of JMeter is the automation. The same test can be repeated after each (minor) release. This is a great […]
Getting started with Eclipse 3.3 WTP 2.0 and JSF – will this JSF editor beat JDeveloper?
A few days ago a brand new Eclipse release popped up in my RSS reader. Eclipse 3.3 with WTP 2.0. After browsing through the new features I was very surprised that it included a brand new JSF editor. I thought this sub-project died very slow and painful. What I will […]
DBConsole 11g (part 2) – Using the SQL Performance Analyzer
Now straight into the more interesting Oracle 11g features. Let’s start using the SQL performance Analyzer and doing so make use of Replay. The Performance section of the DBConsole utility has a link to Advisor Central. The Advisor Central has again two sections: The Checkers section and the Advisors section.
From the Advisor section you are able to click on the SQL Performance Analyzer link.
Here you can choose from three options. I will demonstrate the “Guided Workflow”, but before that I show you the screens of the “Optimizer Upgrade Simulation” and “Parameter Change” sections. The descriptions in the screenshots are self-explainable.
DBConsole 11g (part 1) – An introduction of the new version
Thinking about my first post on Oracle 11g (Beta) I realized that I didn’t mention another great addition to the Oracle (DBA) toolset. OK, of course, it isn’t new as such but… The DBConsole was already introduced in Oracle version 10g. Just like using the Database Configuration Assistant, it gives you a first glance of changes and new features introduced in Oracle 11g. That there are a lot of changes (at Oracle Open World 2006 it was said a grant total of 482) and some of them can be found, configured and used via the DBConsole.
Until this moment, I focused in general on new XMLDB functionality. So my experiences described here are also my first impressions, during my short discovery adventure using the DBConsole.
Using the javax.xml.bind annotations to convert Java objects to XML and XSD
Did you know that when you put the @XmlRootElement annotation on any class you can have an XML representation of that class? When I first saw Java 6 I didn’t get very excited by it, but I have found out some nice things (scripting and Derby for example). This article […]
A quick look at Guice A dependency injection framework by Google
About a month ago I read an entry on Dion Almaer’s blog about Google Guice. On the blog is a link to a video of a google tech talk about guice. I finally watched the video today. A few days before that blog entry an old colleague of mine told […]
Java Platform Debugger Architecture (JPDA) with Tomcat, OC4J, Eclipse, IntelliJ IDEA and JDeveloper
With JPDA it is possible to propagate changes to compiled classes to the server immediately. This is very handy when you’re debugging your class files. With some older applications you have to restart your application server many times to make changes. With JPDA this is history. In this article I […]
Unit testing Javascripts in Java 6 – Getting started with the javax.script api
I intended to reduce the things I do with Javascript. But maybe Javascript isn’t that bad when you can run it inside java. I’m still working on a very ‘interesting’ project with asp and Javascript files. Since I didn’t create a single JUnit for two weeks I thought it was […]
Why you should never ever copy code – An example of complete chaos
It seems innocent, a few lines of code used twice in the same application. But before you know know it those lines appear 272 times in your application! You guessed it right and you’re probably wondering how could that happen. I’ll try to explain what happened and how to prevent […]
SOA Suite Build, Deployment and Test Automation – part 3: test automation

SOA Suite Build, Deployment and Test Automation – part 1
In the latest SOA Suite release Oracle has improved the automated build capabilities. Instead of the Oracle BPEL specific Ant tool (obant, a customized version of Ant) plain vanilla Ant is now used for building and deploying BPEL suitcases. Let’s put it to the test: subject of this blog post […]
Running Webforms without Oracle JInitiator
A few weeks ago one of my customers told me that he lost a sales opportunity because the customer who he was trying to sell his software too had problems convincing his system administrator to install JInitiator. And as we all know it’s often quite a challenge to convince a system […]
Using jQuery, the jQuery Form plugin and Stripes to create pretty Javascript and Java
I recently discovered jQuery, it a blazingly fast Javascript-framework and has a very compact notation. Now some guy made a plugin to submit plain html forms with Ajax and jQuery. Just add some Javascript that says you want to submit the form via Ajax and you don’t have to touch […]
