So it sounds like both the FullHibernatePlugin and the OpenSessionInViewFilter class work. Thanks for the quick replies.
Do you remember how these are configured? The FullHibernatePlugin wiki says only a few lines of configuration are required, but it doesn't say what those lines are. With OpenSessionInView, I add it to my web.xml file, but I get an error that it can't find the class, even though I am fairly certain that the "spring-hibernate3-2.0.8.jar" file contains it, and I triple-check to make sure that jar is loaded. --Dennis On Fri, Oct 23, 2009 at 2:35 PM, Eduard Neuwirt < eduard.neuw...@googlemail.com> wrote: > Hi, > > Obviously there is a gap between Hibernate and Web-Application. > OpenSessionInViewFilter working well, almost.
