Okay I've seen versions of this problem but still can't get my client code running on my PC to connect to the queue created by my Sun machine. I have JBoss running successfully on my Sun. The example that I am using is my version of the message-driven bean example from the JBoss paid documentation. On my machine the version I used comes from c:\JBossBook-2.4.x\examples\src\main\org\jboss\chap4\ex2. I can get the MDB deployed and JBoss to run on the PC and connect to it with my PC client code. I also took the exact same code and was able to do the same on my Sun machine. Now I need to communicate from my PC to my remote Sun host. Here is the output from my PC (Windows 2000) when running the example:

Buildfile: build.xml

[echo] Target run-example-s

[echo] prepare dir: C:\JBossBook-2.4.x\examples/build/chap4
