It seems that Seam has 3 aproaches to use. POJO+HEM POJO+JPA EJB3 I'm coufused about choosing the aproaches. It seems that the EJB3 is recommended by the official. But the framework extending isn't support by now. And also various platform doesn't support. The POJO+HEM/JPA is much platform-independent. And it can also run on EE Server. Comparing to HEM, JPA is less powerful. Many features must be implemented by delegate. Can some one give me a recommendation or advice?
