I'm doing something simple wrong!

Question

Hi,
I have a program which uses SonicMQ messenger to send JMS messages to a server and everything works fine until I pack it up into a JAR file.
I've traced the point in the program it will get up to and it is the first command that uses a package in the SonicMQ API.
I think it sounds like a classpath problem but I've set the classpath to reference all the sonic .jar files and I can't think of anything else.
The wierdest thing is that it works fine on a colleagues computer but we can't see what is different about his setup. He has far less files referenced in his class path although he also has SonicMQ installed.
Any help would be much appreciated as I'm very new to JMS and sonic (like one week!).
Cheers,
Ben.

Answer 1

The main method is in a seperate class which instantiates this one. My program has two methods of communication, firstly via sockets and this all works absolutely fine, even from out of the JAR file, the second using SonicMQ as my JMS provider works great when I run it from JBuilder5 but not from the Jar file. It is all one program which just connects different ways depending on your choices. JBuilder sets the classpath when it runs something and I have cut and pasted all this info into my environment variables and am certain that they point to the class which I am getting a ClassNotFoundException for, that is why I cannot understand what is going wrong at all.
What is the difference between a ClassNotFoundException and a NoClassDefFoundError?
This is my output:
