An easier way to reproduce this issue is to edit the jms-ds.xml file present in %JBOSS_HOME%/server/default/deploy/jms directory and add the following to the connection factory configuration: <use-java-context>false</use-java-context> Then do a lookup of the jndi name JmsXA from a standalone client. Context ctx = new InitialContext(); | Object ref = ctx.lookup("JmsXA"); It *returns NULL* (Does not throw any exceptions, though).
