Hello my friend

About the error "java.lang.NoClassDefFoundError: org/jgroups/Channel " 

You must copy the jgroups.jar which is located in "jboss-4.2.3.GA\server\all\lib" to your "jboss-4.2.3.GA\server\YourMessagingConfigName\lib" directory.

I have the  default config name, so i have to copy to 


I hope this could fix your error


See ya =)
