Hi, The problem is that your web service and WicketFilter are configured to listen on different filter paths, e.g. /webservice/* and /wicket/*. If there was a request to /wicket/* that had bound a Session then the call to /webservice/* will be OK, but otherwise it will fail because while trying to create a Session Wicket needs RequestCycle. The solution is simple - move #getSessionFactory() to YourWicketApplication.
