I was using the xml descriptor to declare the JMS connection factory used by some of my EJBs. By adding a dependency for each bean which uses the connection factory to the jboss.xml deployment descriptor I managed to work around this issue. There are some things which made this more confusing that it has to be. 1.) The error mentions jms/ConnectionFactory rather than my custom connection factory. This is rather misleading. It could have been much simpler to determine the cause of the problem if it told me that my custom connection factory was not found 2.) The startup sequence / order has been changed from 4.2.3 to 5.1. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/610051#610051] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
