EJB module initialization listener

Question

Can I define a listener for EJB 3.0.jar that is called in module / context initialization? Like for ServerContextListener for web project?

Answer 1

AFAIK, not with EJB 3.0. With EJB 3.1, you can use EJB Singleton for this.

From Application Launch / Completion Statement :

   1:  @Startup
   2:  @Singleton
   3:  public class FooBean {
   4:   
   5:    @PostConstruct 
   6:    void atStartup() { ... }
   7:   
   8:    @PreDestroy
   9:    void atShutdown() { ... }
  10:   
  11:  }
