@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.

Answer 1

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
   }
}

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.
