Custom SessionListener, name is not bound in this context, javax.naming.NameNotFoundException

I am trying to implement HttpSessionListener so that users of this listener can register implementation of ISessionEvent interface to session Events.code is below:

public class MySessionListener implements HttpSessionListener{

 @Resource
 ISessionEvent sessionEvent;

 public ISessionEvent getSessionEvent() {
  return sessionEvent;
 }

 public void setSessionEvent(ISessionEvent sessionEvent) {
  this.sessionEvent = sessionEvent;
 }

 @Override
 public void sessionCreated(HttpSessionEvent arg0) {
  sessionEvent.SessionCreated(arg0.getSession());
 }

 @Override
 public void sessionDestroyed(HttpSessionEvent arg0) {
  sessionEvent.SessionDestroyed(arg0.getSession());
 }
}

When user implement ISessionEvent and add as a bean, SessionCreated and SessionDestroyed functions of implementation will be called when these events occured. You can ask why dont you just write inside listeners methods, i dont i'm just trying.

When i try the code above i got the following error message:

javax.naming.NameNotFoundException: Name com.mehmet6parmak.sessionlistener.MySessionListener is not bound in this Context

Resource annotation causes the error but i could not resolve it.

Thanks All...

Interface and Implementation

@Resource
public interface ISessionEvent {


public void SessionCreated(HttpSession session);
 public void SessionDestroyed(HttpSession session);

}

@Resource
public class SessionEvent implements ISessionEvent {

 @Override
 public void SessionDestroyed(Htt开发者_运维百科pSession session) {
  System.out.println("From Session Event Callback(Destroy):" + session.getId());
 }

 @Override
 public void SessionCreated(HttpSession session) {
  System.out.println("From Session Event Callback(Create):" + session.getId());
 }

}

Bean Definition

<context:annotation-config/>
<context:component-scan base-package="com.mehmet6parmak">
</context:component-scan>

<bean id="sessionEvent" autowire="byName" class="com.mehmet6parmak.sessionlistener.SessionEvent"></bean>

Solution:Using the method used in link works.

It's merely because ISessionEvent is not managed, I believe. Does it have @Resource annotation? Something like,

@Resource
public class ISessionEvent {...}

i have no experience about annotated listeners and Co. but, i checked the method on Specs, i met the following:

protected static void lookupFieldResource(javax.naming.Context context,
                                          java.lang.Object instance,
                                          java.lang.reflect.Field field,
                                          java.lang.String name,
                                          java.lang.Class<?> clazz)
                                   throws javax.naming.NamingException,
                                          java.lang.IllegalAccessException

Inject resources in specified field. Throws: javax.naming.NamingException java.lang.IllegalAccessException

that means, you try to inject a resource into your field which must be a JNDI resource.

@Resource annotation works with a JNDI- entry: http://download.oracle.com/javaee/5/api/javax/annotation/Resource.html

did you forget to define your resources in JNDI Context?
