OK, that's good. So -- uh - how would I configure OpenSessionInView? I attempted to do it, but even after I loaded the spring-hibernate3-2.0.8.jar file, I got a ClassNotFound error, so I couldn't even get past that.
And you are absolutely correct about it being rather interesting. But it seems so common, that there should be a common and standard way of dealing with it, but so far it seems not. --Dennis ________________________________ From: Eduard Neuwirt <eduard.neuw...@googlemail.com> To: Struts Users Mailing List <user@struts.apache.org> Sent: Fri, October 23, 2009 3:19:09 PM Subject: Re: Struts2 / Hibernate Question Hi Dennis, sorry i don't know anything about FullHibernatePlugin.
