When developing GWT (Google Web Toolkit) applications, the GWT hosted mode is an invaluable tool, as it allows for short development cycles. Whenever you change something in the GWT client code and hit the “Refresh” button it will compile the change, reload the application and show the result of my change almost immediately. In theory, […]
Extensibility jBPM style
Currently I am involved in a project that is moving away from a proprietary workflow solution to a JBPM based workflow solution. One of the first things I attempted to do was try and make jBPM integrate with the identity management solution used in the project. I knew that jBPM comes packaged with some sort […]
What to do with an Interruptedexception
Many java methods, such as Thread.sleep and Process.waitFor can throw an Interruptedexception. InterruptedException is a checked exception and as such requires you to explicitly catch it. Up until recently I’ve always simply swallowed this exception. I was fairly confident that this was the proper way to deal with this exception because this is how I’d […]
Maven wastes more time than it saves. Cast your vote
I just finished added a pole to this blog and the first question I would like to ask my audience (all 3 of you 😉 ) is. Does maven waste more time than it saves compared to say an ant or make based build. In my experience this statement holds true however I am curious […]
JPA missing non-exotic features
Ever since the Java Persistence API was announced there has been a lot of talk, both good and bad, about this specification. Many people have pointed out that a criteria API and something like hibernate filters are currently missing. However these features might be considered “exotic” and I can largely live without them. However a […]

It seems JavaFX was released today. There are some pretty good looking demo’s over at http://blogs.sun.com/chrisoliver/category/F3 and https://openjfx.dev.java.net/ Worth a look.
Guice versus Spring
Craig Walls, author of spring in action just blogged on the subject of Spring and Guice. Pitting the two inversion of control containers against each other he concludes : “I’m glad that I spent the time to learn a little about Guice, but I’m not all that “juiced” about using Guice. In addition to all […]
Spring and DWR – Ajax made Easy
Direct Web Remoting (DWR) is an Open Source initiative that provides easy Ajax for Java. Besides being the best Ajax framework for Java developers, it has one more big feature, at least in my opinion. It integrates very nicely with Spring, by provides the means to easily remote your spring-managed beans to JavaScript. However, up […]
Password protecting web applications in tomcat.
A few days back I wanted to take an existing application, deploy it to a staging environment and password protect it without having to change the application code. How hard can it be right? As it turns out it’s not that hard but way, way harder than it should be. There doesn’t seem to be […]
Disabling the Firefox DNS cache
If you, like me, make frequent changes to your host file, for instance because your staging and production environment both listen to the same vhost. You will have probably noticed that it takes Firefox a while to pick up on the alterations you made. This is because in order to improve performance by default Firefox […]
