Ok, thanks to all you guys I have the servlet calling out to the ejb from the servlet. The ejb lookup and method calls are in a processRequest method that is called from the doGet method.
Tracing it i find that it gets past the InitialContex and the lookup, It gets to the ejb.home.create() and gives a NullPointer Exception. Like this:

Not sure why. I can hit the ejb from my java client and it works ok.
Any suggestions where to look or how to pin point it more?

I found the error.
It was a due to a bad try/catch block that was not allowing the remote interface to be created. After a little house keeping it works great. This is my first attempt at connecting a jsp/servlet/ejb and fully implemting the MVC architecture.
Thanks to all those who encouraged me the past week. Now on to those enhancments........
