The application does not find the javax.persistence class. But however if I create a class with a main method and try to add a record manually it is working. Therefor the problem only occurs if I try to add a record by a form in the webapplication.
I hope someone can help me, what am I doing from. I am using hibernate 3.5.
Thanks for your help
