Hi,
I'm new to JBoss and am trying to setup sample code to use the JBoss messaging service.
I'm trying to use the included TopicSendRecvClient.java test class to access the following default JNDI objects to send/receive JMS Text messages.
TopicConnectionFactory
topic/testTopic
Problem:
In Setup 1 (Local Workstation Environment listed below), I can retrieve and use the objects normally.
In Setup 2, I have installed the same version server on a remote linux server. My problem is that when I try to retrieve the same objects through JNDI, I have an exception saying that the objects are not bound. This doesn't seem to be the case though since I can see the objects through the JMXConsole JNDIView.list() method on the same remote Linux server.

Setup 1:
Environment: Windows XP Pro (Local Workstation)
JBoss: 4.0.5 Installed via jems-installer-1.2.0.GA.jar
The server here started correctly.
Setup 2:
Envrionment: Linux Server (Remote)
JBoss: 4.0.5 Installed via jboss-4.0.5.GA.zip.
The server here experienced startup errors from a fresh install. I don't know if this is a red herring relating to my problem but I'll list them anyways.
Startup Errors:

Any help would be greatly appreciated to help me figure out why I can't connect to my TopicConnectionFactory object via JNDI on the remote linux server.
thanks!
