I don't think this is the code that is throwing the exception. Going by the exception stacktrace you posted, the exception is being thrown when some object is being injected anonymous wrote : at org.jboss.injection.JndiPropertyInjector.inject(JndiPropertyInjector.java:65) | at org.jboss.ejb3.AbstractPool.create(AbstractPool.java:111) | at org.jboss.ejb3.StrictMaxPool.get(StrictMaxPool.java:141) When exactly does this exception occur. Please post the entire console logs along with the complete exception stacktrace. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197270#...
