And going by what you have posted, you seem to be doing that by setting the CLASSPATH. But, you are running a jar file using java -jar client.jar, in which case, the CLASSPATH is totally ignored. When running the jar file, you need to set the Classpath through the MANIFEST.MF file in the META-INF folder of the client.jar. Have a look at http://java.sun.com/docs/books/tutorial/deployment/jar/downman.html to see how you can add classes/jars to the jar's classpath through the manifest file View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139991#...
