Hi, thanks for having a look.
It's trying to contact a JMS Topic. Both instances use identical properties for the initial context, and it gets names for most things, just nothing related to JMSTopics.
The point of Failure in my source is
TopicConnectionFactory tcf = (TopicConnectionFactory) initialContext.lookup("RemoteConnectionFactory");
This lookup fails from the EXE, but not from Eclipse.
If i try to do the lookup with "java:jboss/exported/jms/RemoteConnectionFactory" the errormessage changes from URI: NULL to URI: java.
This confuses me even more since to me this indicates it is working with the string but somehow looses (?!) it underway.
