hi thiage,
you're right HttpSessionActivationListener is another possibility :)
i dont recreate the registry in my HttpSessionListener, i just reuse the
one created by my tapestry listener
My TapestryListener snippet (could be a filter):
public class TapestryListener implements ServletContextListener
{
public static final String REGISTRY_CONTEXT_NAME =
"org.apache.tapestry5.application-registry";
public void contextInitialized(ServletContextEvent sce)
{
// same code as in TapestryFilter
....
registry = appInitializer.createRegistry();
// set registry in context
context.setAttribute(REGISTRY_CONTEXT_NAME, registry);
...
// same code as in TapestryFilter
}
}
My HttpSessionListener:
public final class MyHttpSessionListener implements HttpSessionListener
{
...
public void sessionDestroyed(HttpSessionEvent event)
{
HttpSession httpSession = event.getSession();
...
Registry registry = (Registry)
httpSession.getServletContext().getAttribute(TapestryListener.
REGISTRY_CONTEXT_NAME);
if(registry == null)
throw new RuntimeException("No Tapestry registry
found. Please check that TapestryListener or -Filter is added as
<listener>");
... //do something
}
}
g,
kris

My approach was to use a RequestFilter to put in the session an object
that implements HttpSessionActivationListener. It will be notified when
the session is created and when its destroyed. No need to create the
Registry manually. :)
