Thank you very very VERY much Francesco! I'll carefully read your article, and the documentation. anonymous wrote : The webservice encoded using ejb 3.0 what do you mean ? using annotations @Webservice ? About "using EJB 3", yes, I meant "@WebService" annotations over Session Beans, and so on. Actually, there's no need to include Entity Beans or Message Beans at the moment. anonymous wrote : if I understand your requirement for this you don't need Seam to use them. Anyway Seam helps a lot if you have EJB in your application, you'll save a lot of time wasted in writing useless Java Bean code. (just to mention one) Do you mean annotations like @NotNull? If so, yes, I've seen it in the examples, it's a very nice feature, but, you're right, I'm not focusing on them, now. Thank you very much, once more!
