I already was using 2.0.1.CR1. I just had thought Seam did not get initialized properly and so the Entity Manager. And I thought that was because i had something missing with the embedded JBoss. I discovered the thegenerated log4j configuration was at ERROR level so i did not see what actually happened down there. I changed it, traced it and solved the issue. Thank you very much.
