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
