Is there a way to detect the undeployment of an EJB?

Question

Hi,

I need to do some clean up (release open ports,etc.) before my EJB Session Bean is being undeployed, is there a way to detect this?

The EJB is running on Weblogic 10.0.

Answer 1

Can you not make use of the session bean lifecycle by using @PreDestroy as illustrated here ?

Answer 2

Listen to the lifcecycle events using the ServletContextListener interface.

Implement the interface in a class, and register it in web.xml:

 <listener>
<listener-class>
 my-class-with-servlet-contextlistener-interface
</listener-class>
  </listener>

Answer 3

Solved the issue in a Weblogic-specific way by implementing an ApplicationLifecycleListener. Details can be seen here
