probably you're right! thanks. I now don't use @In annotation and it works. I am new to seam and trying to realize when to use @In and @Out ? Since I am not a pragmatic programmer yet, I sometimes program blindly. Could you please tell me the idea of @In and @Out in brief? (if you have enough time to type a few words) AFAIK, seam is not ejb3. So I feel a little bit inconfident while programming in seam. thanks.
