warp persist, guice & wicket: start warp persist before http request

[Christoph]

Hi all,

I am using Wicket together with Guice and Warp Persist/Servlet.
I have registered the PersistenceService in the contextInitialized
method. However, I would like to do some data loading from the
database when wicket starts, and need to use Hibernate Daos. I am
getting the error:

org.hibernate.HibernateException: No session currently bound to
execution context
at
org.hibernate.context.ManagedSessionContext.currentSession(ManagedSessionContext.java:
50)
at
org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:
591)
at
com.wideplay.warp.hibernate.SessionProvider.get(SessionProvider.java:
42)
at
com.wideplay.warp.hibernate.SessionProvider.get(SessionProvider.java:
32)

Using Hibernate from an HTTP request is no problem. How can I
configure Warp to use it directly from WicketApplication?

Thanks a lot, Christoph

public class Init extends WarpServletContextListener {

@Override
public void contextInitialized(ServletContextEvent event) {
super.contextInitialized(event);
INJ.getInstance(PersistenceService.class).start();
event.getServletContext().setAttribute("injector", INJ);
}

@Override
public void contextDestroyed(ServletContextEvent event) {
super.contextDestroyed(event);

}

You basically need the PersistenceFilter to appear above the WicketFilter. I think that should fix it.
