I am getting a Session is closed error

I am using the HibernateUtil class to manage the session and transaction as is Hibernate in action book.

My service classes are aslo specified in the book

It happens when I saveorupdate two different tables and continues to happen after wards. It does not happen with select.

Thanks for the help in advance

I don't know what you are doing wrong. Please continue this discussion in the regular Hibernate User forum and include all necessary information (as mentioned in the red box).
