usage of hibernate connection in wicket application (during startup)

[Christoph]

Hi all!
I am using Wicket together with Hibernate and Warp-persist/servlet. In
my Init class, I have registered following two methods below. However,
it seems that I can access database objects via DAOs only as soon as a
request is sent to the server. I would like to use them before (during
start up of the wicket application) in order to load some objects from
the database, which are shared across the application.

Currently, I am getting the error: Exception starting filter
wicket.catadvisor
org.hibernate.HibernateException: No session currently bound to
execution context when running a @finder method to return some
database objects.
How do I need to configure warp-persist in order to use it in wicket
applicaiton in the init() method during startup?

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);

}

Hi Christoph,

IF you are using Open Session In View (session per http request) you need to look into using the WorkManager, if you need a hibernate session outside the scope of an http request.

Hope this helps,

Yaniv Kessler
