I am currently developing a pilot EJB project in IBM RAD6 Websphere6.0 and testing out a remote EJB invocation. I have developed a web project that runs on websphere6.0 and my ejb works fine. I also deployed that same project on another machine ( both windows machines ) and ran remotely via the web project ( test jsp calling a servlet that invokes the EJB home interface ) and all works fine.
Now I want to test that same code from a JVM inside rad6 using the same default eclipse JRE instead of a web container. So I create a simple java program which duplicates the same ejb invocation, I have added all the jars required one at a time onthe classpath till I can get to the point where I get this error

I have tried my best to find out which jar I am missing. I went through 'every' jar that is on my web classpath trying to find which jar has this package but I could not find it.
I also looked this up on the net but to no avail. Does anyone know where this class is and how come this is not documented anyhere ?

Your help will be greatly appreciated.
