Thank you for your answer.

I use glassfish app server for my project, maybe there is something wrong?

To clarify my project structur:

Entities + SessionBean:

GWT Servlet:

I have got a GWT Client Side where I temporally want to use POJOs from the EJB Project.
Then there is a GWT Servlet, which is there to communicate with my EJB Project.
At least I have got a EJB Project with my Session Beans for managing the Persistence Entities,
which should be able to be transferd to GWT Client Side. 
When I want to test if I could persist this little example, I got the following Exception:

Seems like I couldn`t use Transactionmanagement..
And how can I tell my GWT Project which Persistence Entities I have?
