NetBeans

One of the not-so-great things about developing Java web applications is the fact that, after a few redeployments, sooner or later the web container JVM needs to be restarted due to Out Of Memory errors. This has been true in every combination of development environment and web server I have used so far, and until last week Netbeans 6.8 + Glassfish 3.0.1 was no exception. The cause of Out Of...

GUI

Bean validation is a nice API for for validating Java objects and is included in Java EE 6. But it can also be used anywhere, regardless of the layer. It can be used with or without JPA and in a stand alone Java SE. It formalizes and encourages the validation approach at the domain model level. It helps in de-duplication of the validation logic that we are accustomed to having all over the place...

J2EE

CDI (Contexts and Dependency Injection for the Java EE platform) is defined in JSR-299 and enhances support for dependency injection in Java EE 6. The more I use CDI the more I like it...However, I couldn't find a simple example of how to configure your application with CDI by reading configuration attributes from a file. Here is an example of how it can be done: Specifying injection points...
