I think, its better you see the stack-trace you sent. Its clear that you're using different classes which are not compatible and therefore there's error. You gotto either using hibernate4 specific SPRING classes or use hibernate 3.X:mad:

You'll find that, while Spring 3.2 supports Hibernate 4, Spring 3.2 doesn't provide Hibernate 4 versions of HibernateTemplate, HibernateDaoSupport, etc.

In theory, this is a good thing. However, if you've built an entire DAO infrastructure using these *hibernate3.* artifacts, you'll be unpleasantly surprised by how broken your application will be when moving to Spring 3.2 and Hibernate 4. Even the classes that are supposed to support Hibernate 4 don't have the same public APIs as their hibernate3 versions.

For instance, compare the JavaDocs of hibernate4.SessionFactoryUtils and hibernate3.SessionFactoryUtils.

As you'll see, if your app has been using SessionFactoryUtils.getSession() to get a Hibernate Session bound to the current thread, you can't just switch to hibernate4.SessionFactoryUtils because there is no longer a getSession() method! Even if this behavior is being handled by Hibernate's SessionFactory or the Spring LocalSessionFactoryBean, it would have been nice for SpringSource to leave the method on SessionFactoryUtils and just delegate to the object doing the real work. That would have minimized some of the rework of applications migrating to Spring 3.2 and Hibernate 4.x.

FWIW, I finally got Spring 3.2.0 + Hibernate 4.1.9 working now (still with some unanswered questions). Despite it not being as smooth a migration as I'd hoped it would be, it isn't insurmountable, so hang in there!
