7. Problem with Toplink Cache & parallel access of 2 servlets

I have two servlets (a GWT RPC servlet and a normal HttpServlet) that use the same stateless session bean to create and read database entities. The second servlet is not used as often as the first, and most of the time when I use it I get an Optimistic Locking Exception or something similar (Entity already exists etc.).
