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:

13:39:52,179 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/edi]] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) Session event listener threw exception: java.lang.RuntimeException: javax.naming.NameNotFoundException: java:app/EDI_EJB/WorkflowMessageManagerBean
