I have 2 EJB projects, let's say ejb1 and ejb2, and I put hiberante mapping file and utility class related hibernate(such as factory, connection etc) in ejb2. now there are some database operation, like read/write data method in session bean in both ejb1 and ejb2 projects, i'm now sure it is ok or not.

before my hibernate mapping files and database operation through hibernate is only in ejb1 project. and I had entity beans in ejb2 project, and they worked without problem. but since I replaced entity bean with hibernate, like above said, there are some problem in my j2ee application.
