The DEBUG logs are available in server.log (as you note later in this post). We would mainly be interested in org.jboss.ejb3 DEBUG logs.

If possible, zip it and attach it to the JIRA issue https://jira.jboss.org/jira/browse/EJBTHREE-1751

Could you please post that webservice code including annotations?

The actual problem that we see in this issue (and the one noted in the JIRA) is related to ordering of deployment units. So if you have a EJB in one jar and the EJB depends on some other EJB in a different jar, then chances are that because of deployment ordering, the injection might fail. If both those EJBs are within the same jar then you wont be noticing this issue. This issue is specific to AS-5.x.

>From my understanding of this issue, i would have expected the mappedName attribute on @EJB injection to fix the issue with injection (even if the EJBs are in different jars).
