If you looking for a general J2EE framework to run Web Services on for testing and educational purposed have you looked at the J2EESDK from Sun?

GLUE is one framework you can use (themindelectric.com).
I've used AXIS embeded with Tomcat and JBoss to do webservices.
I don't have any examples to give you as what I'm working on is still in progress...
If you use access, you'll need to deploy the servlet engine in JBoss.
