Hi Ben, thanks a lot for your answer. My components.xml had the lines you mentioned, the problem was something else (fortunately it is solved now!): The exploded-archives dir contained old files which weren't in the src branch anymore; they caused the trouble. An ant clean helped. Everything is fine so far now. Nevertheless it would help if the error message would contain the name of the bean that causes the trouble. Thanks for your clarifying comments and your help. :-) See you, Jörg View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990824#...
