With AUTO I wouldn't go register it directly and see if it fails. I would go and validate it first, if it passes then register it directly - ok it can still fail - but we at least know we tried our best. With STRICT we also validate first - if it doesn't even pass validation throw an exception - and if it later fails ofcourse. NONE is ok as it is. Sure. You are the one writting binding code. See org.jboss.kernel.plugins.deployment.xml.[name]Handler. How this goes with retro stuff - don't know yet. :-( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3986170#...
