@jaikiran Thanks for your information. Now, it's clear that it is an intend behaviour and of course it makes sense. @PeterJ Yes, I have checked out the branch "Branch_5_0" installed ant and maven. After that you can build 5.0.1. BTW, can take > 1h. @All I have found some docs about the @Service annotation here: http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html/j... Chapter "5.1. @Service EJBs" contains all relevant information about the annotation and explains the behaviour.
