[JBoss-user] Problem connecting to client when publishing message

[Beau C. <bcronin@ICSI.Berkeley.EDU>]

I'm trying to set up a pub/sub JMS Topic to inform clients of changes
made to the data on the server.  The remote client successfully
subscribes to the topic (using a javax.jms.MessageListener), but then
there are problems when messages are published by an MBean to the topic.

I'm getting the following message in the server log when the MBean
publishes a Message which is then attempted to be pushed to the
subscribed client:

14:03:03,206 ERROR [OILClientIL] Cannot connect to the

There is no firewall or anything between the JBoss machine and the
machine running the client application, but it seems as if it is having
a problem connecting to the client.  Any idea what the problem could be?

JBoss 3.0.6/Java 1.4.1/RedHat Linux
