Java EE (Java Enterprise Edition) General Discussion

Hi All,

Currently I am using Jboss 5.0.1 server and using EJB3 in my application. I have created the timers. I m calling the timers from the servlet (init method) during the server start up. And i have calling the cancelling the method from the destroy method. But while stopping the server i munable to cancel the server. I am getting the below exception. My application name is loa. It seems the destroy method of the servlet is getting called after all the EJBs are undeployed.
