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

This tutorial code aims to solve a problem I have come across a lot lately on our own projects but also within the Google Web Toolkit (GWT) forums lately. The need to know when an Remote Procedure Call (RPC) has finished. Although this somewhat goes against the grain of the essence of an Asynchronous call a lot of developers still see the need to know when it has ended, sucess or failure. Below aims to solve this.
