Hi, i am using Hibernate 3.0 in a WebService Servlet to make DB operations.

But i don't really know how to use Hibernate in a Servlet. How shall i work with the SessionFactory?

Now i open a Session and a Transaction in the Method and at the end i commit the Transaction and close the session.

This works for the very first time after i deployed the application. At the second time i get the error message "Could not connect".

What can be the problem?
