Most of the traditional Java EE patterns are now obsolete. They were usually workarounds for limitations in the J2EE architecture. Well, this may be overstating a bit, for example, some people still like to use DAOs in EE 5, though to me it seems overkill. Seam actually starts to develop its whole own set of patterns (eg. manager component, the various search screen patterns, etc), but most of these are still only vaguely understood ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959968#...
