The current DeployersImpl stores only the root cause of an exception thrown during deployment in the IncompleteDeploymentException - it would be more useful if the entire exception (as orignally thrown, not including any causes added by the MC) was present there. It's also worth noting that the whole deployment error reporting system isn't the easiest to use/extract information from. However, I'm not entirely sure how it could be improved. Perhaps the ability to install a custom exception handler which get's notified on a context in error? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240744#...
