@PostConstruct not working in JBoss 5

Question

I have a servlet that I cannot change (com.sun.jersey.spi.container.servlet.ServletContainer of Jersey RS) . What I can do is create a subclass of it. However, I needed that when the servlet is initialized it runs one function of my subclass. I cannot override the init method because it has the Jersey code.

I tried to use the annotation @PostConstruct on a method to make it run after initialization but it does not work (but it does work under Tomcat 6). In web.xml the class is set to run on startup.

Why can't you override `init`? The method isn't `final`, so what's the problem? — skaffman, May 16 '12 at 10:27
I ain't no Java expert, but I would need to copy the whole code from the existing source code to mine right? And also, the init(WebConfig webconfig) access a private attribute webComponent. — Miguel Ribeiro, May 16 '12 at 10:33
@No, no copying required. See my answer below. You may need to beef up your Java knowledge to tackle this, this is quite basic inheritance stuff. — skaffman, May 16 '12 at 10:37

You should be able to subclass ServletContainer, override init, invoke the superclass method then perform your own logic, i.e.

public class MyServletContainer extends ServletContainer {

   public void init() throws ServletException {
      super.init();

      //... perform custom initialization logic here
   }
}

mother of dumbness :O Nothing to do here! I seldom have the need for inheritance and forget these kind of *basic* thing! – Miguel Ribeiro May 16 '12 at 11:01

Check if you have some of these jars "commons-annotation.jar, geronimo-annotation_1.1_spec, jboss-annotations-api_1.1_spec" in your webapp lib and remove.
