SessionListener (Apache Turbine 5.1 API)

java.lang.Object
- org.apache.turbine.services.session.SessionListener

All Implemented Interfaces:

Serializable, EventListener, HttpSessionActivationListener, HttpSessionListener
```
public class SessionListener
extends Object
implements HttpSessionListener, HttpSessionActivationListener, Serializable
```
This class is a listener for both session creation and destruction, and for session activation and passivation. It must be configured via your web application's web.xml deployment descriptor as follows for the container to call it:
```
 <listener>
   <listener-class>
     org.apache.turbine.session.SessionListener
   </listener-class>
 </listener>
 
```
<listener> elements can occur between <context-param> and <servlet> elements in your deployment descriptor. The sessionCreated(HttpSessionEvent) callback will automatically add an instance of this listener to any newly created HttpSession for detection of session passivation and re-activation.
