Hi,
I have been able to fix this error already.. the classpath define was
not right... but now i am getting a different error while using the
Listen command... It says
invalid packet source (check your MOTECOM environment variables)
Can anyone help me on this???
Cheers!!!!!!

Hi,
What JVM are you using? It appears that you're using gcj. I'd
recommend looking at your PATH or trying 'which java' to see which java
is being invoked. You should setup your PATH to locate either the IBM
or Sun JVM.
Hope that helps,
