I just started working on Jboss ESB am using Jboss 5.1.0 and ESB 4.10 and JBDS for development.
I am writing a custom action class where i am using 3rd party jars when compiled every thing fine and exported the .esb file to server and when tried to execute the action class by sending ESB message i am getting Class not found exception. the jar file i am using is available in D:\jboss-5.1.0.GA\server\default\tmp\vfs-nested.tmp.
Shall i have to do some configuration in JBoss.
Can you paste a stack trace? How are you invoking your service? Is the jar included in your ESB archive?
