I will do that. Thanks. But what I dont understand is that I have not changed the PersistenceFacade.java and the classes that uses it has not been changed either.
I have only upgraded Struts and the dependencies.

When closing a database connection like that you should always check that it is not null before closing it. Why it is null I could not tell you. You should step through your code and make sure it is doing every it should be before you call the close. If yuo are not obtaining a valid connection I suggest starting there. You should probably be closing your database within a finaly block as well. Chris > Of course.
