Thank for your reply,yuan. I read Beating Rails in its own game (5-minute movie on Seam Eclipse Tools),It's cool! I tried the framework Seam Gen provides,but I can't understand it fully. I can't find the easiest way to use it,so I try the way showed above. Can you tell me how to get the code of the demo you showed in your blog,I will study it,It will help me a lot. thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029596#...
