Wow I love that. Somehow I mistakenly thought it didn't work that way, thanks. As a related question : is there a way to get the 'real' session instead of the proxy on a call to getSession()
The reason I'm asking is that in a lot of cases I want to use (Hibernate's) DetachedCriteria's, so I can make a criteria, pass that as a parameter to a repository and let the repository get the current session and create a real criteria. (For reasons of seperation) This is done through detachedCriteria.getExecutableCriteria(getSession()); However this always gives a classCastException, like: java.lang.ClassCastException: $Session_11b08fbaf1e cannot be cast to org.hibernate.engine.SessionImplementor. for a related post (similar problem) see: http://www.nabble.com/Hivemind-creates-proxy-Hibernate-Session-td9845916.html Therefore I need the 'real' object. diong getSession().getSessionFactory().getCurrentSession() would solve my problem, since that would be both the session of the current thread and the real object, but (as described in method 2 of my post) the context assigned to be tapestry-hibernate isn't there when accessing the session in this way. Any suggestions on how to solve this as well? Much apreciated! Howard Lewis Ship wrote: > > If you are using tapestry-hibernate, the injectable Session service is > a perthread proxy.
