First of all, you are using JBoss Messaging 1.x , not JBoss MQ (default JMS provider in AS 5.0 is JBM) - I can see that in the stack trace. | javax.jms.JMSException: There is no administratively defined topic with name:SERVER/TOP | In JBM 1.x Having a forward slash in a destination name is illegal (there was a recent thread on this on this forum). You could try defining your topic as server.top, using a dot '.' to delimit words in a destination is also more consistent with how many other messaging systems define topic hierarchies.
