In our business, myself and the technical staff have computing related degrees, the rest of the staff are also educated to university level. I have a degree in Computer Science but does it make me a scientist? Or am I an engineer, or a business man (as myself and Julie own the business)?

I have written a quick tutorial on how to perform XSS using GWT and JSONP within a J2EE based container.

The tutorial can be viewed at:

I have recently compiled a tutorial on how to make the GWT, Spring and Hibernate technologies work together.

The various sections and links are listed below.

Part One - Configuration and Initial Setup 

Part Two - Hibernate Annotations and Example DB Setup 

Part Three - GWT Server side and RPC Plumbing

Part Four - Tomcat Setup and Deployment

Part Five - Migration to GWT 1.5
