    Ejb not found on http session timeout

      Hi everybody!

       

      I have a problem of getting ejb local reference in Http session listener in method #sessionDestroyed(HttpSessionEvent)

       

      There is code snippet below:

       

      @WebListener

      public class SessionCleanUpListener implements HttpSessionListener {

       

          /**

           * @see HttpSessionListener#sessionCreated(HttpSessionEvent)

           */

          public void sessionCreated(HttpSessionEvent arg0) {

          }

       

          /**

           * @see HttpSessionListener#sessionDestroyed(HttpSessionEvent)

           */

          public void sessionDestroyed(HttpSessionEvent arg0) {

              ServiceLocator.getInstance().getWorkflowMessageManagerBean().removeNotPersistentItems(arg0.getSession().getId());

          }   

       

      }

       

      ServiceLocator is a utility class to obtain ejb reference.

       

      public class ServiceLocator {

       

          private final static String JNDI_NAME_WORKFLOW_MESSAGE_MANAGER_BEAN = "java:app/EDI_EJB/WorkflowMessageManagerBean";

       

          private final static ServiceLocator SERVICE_LOCATOR = new ServiceLocator();

       

          private final Context context;

       

          private ServiceLocator() {

       

              try {

                  context = new InitialContext();

              } catch (NamingException e) {

                  throw new RuntimeException(e);

              }

       

          }

       

       

          public static ServiceLocator getInstance() {

              return SERVICE_LOCATOR;

          }

       

         

       

          public WorkflowMessageManagerBeanLocal getWorkflowMessageManagerBean() {

              try {

                  return (WorkflowMessageManagerBeanLocal) context.lookup(JNDI_NAME_WORKFLOW_MESSAGE_MANAGER_BEAN);

              } catch (NamingException e) {

                  throw new RuntimeException(e);

              }       

          }

       

      }

       

      When session timeout is triggered I got following exception in jboss console:
