Currently the mule http.servet classes are based on http GET and POST calls. However, modern web applications depend strongly on AJAX technology. The Google Web Toolkit (GWT) is one framework available that allows development of both server and client sides code with Java, and uses remote procedure calls to wrap AJAX connections. Client side java is translated into JavaScript, ether during runtime to allow for debugging or before execution to increase speed.

This project would house a series of classes that could facilitate incorporating mule into web applications made with the Google Web Toolkit. Because GWT is written in Java 1.4, code from the mule tree could actually be exicuted by the web client. Or the mule layer could remain on the server allowing the web application to be mule independent.
