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 at com.nvcm.edi.web.factory.ServiceLocator.getWorkflowMessageManagerBean(ServiceLocator.java:82) [classes(inlove) at com.nvcm.edi.web.listener.SessionCleanUpListener.sessionDestroyed(SessionCleanUpListener.java:26) [classes(inlove) at org.apache.catalina.session.StandardSession.expire(StandardSession.java:690) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.session.StandardSession.isValid(StandardSession.java:585) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.session.ManagerBase.processExpires(ManagerBase.java:390) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.session.ManagerBase.backgroundProcess(ManagerBase.java:375) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1316) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1601) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1610) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1610) [jbossweb-7.0.13.Final.jar(inlove) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1590) [jbossweb-7.0.13.Final.jar(inlove) at java.lang.Thread.run(Unknown Source) [rt.jar:1.7.0_05] Caused by: javax.naming.NameNotFoundException: java:app/EDI_EJB/WorkflowMessageManagerBean at org.jboss.as.naming.InitialContext.lookup(InitialContext.java:121) at org.jboss.as.naming.NamingContext.lookup(NamingContext.java:214) at javax.naming.InitialContext.lookup(Unknown Source) [rt.jar:1.7.0_05] at com.nvcm.edi.web.factory.ServiceLocator.getWorkflowMessageManagerBean(ServiceLocator.java:80) [classes(inlove) ... 11 more We use Java 1.6, jboss-as-7.1.1.Final, Ejb 3 on our project.
