Thank for your replies.
Finally ,I found TapestryFilter has put registry into servlet context,so I
do it like this,
MyHttpSessionListoner.java
@Override
public void sessionDestroyed(HttpSessionEvent se) {
//Get Tapestry IoC Registry
Registry registry = (Registry)
se.getSession().getServletContext().getAttribute(TapestryFilter.REGISTRY_CONTEXT_NAME);
ISocialPartyOnlineService socialPartyOnlineService =
registry.getService(ISocialPartyOnlineService.class);
//Do my session sessionDestroyed logic
}
