I think its more up to personal preference and how you want your code organized. Bijection can be nice from the standpoint of shorter component names and your jsf more straightforward because you can refer to entities directly. But if you overdo this, your backing beans can get confusing because now you don't know where everything this being injected from. Again, code organization is the biggest concern (for me anyway) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078867#...
