Here are several excellent AJAX
and GWT
Training Tutorials that are derived from Marty
Hall's world-renowned live programming training courses, hosted on
courses.coreservlets.com. These are
intended as a fast introduction
to the basics of Ajax and Google Web Toolkit (GWT) for people that
already know how to
write the server-side part of the process using servlets and JSP.
Although these tutorials provide the code for all of the servlets and
JSP pages used, it does not explain the server-side code in depth or
discuss how to deploy it...for detailed tutorials on writing
server-side
Java applications and explanations on how to deploy them on Tomcat,
please see these
Java EE tutorials.
These
tutorials come with a complete set of text, PowerPoint
files, pdf documents, and source so that your goal of learning
Ajax and Google Web Toolkit
will be easier and more productive. What follows here are the major
topics, pdf tutorials files, and source code for these AJAX
and GWT Tutorials:

code: GwtProject1.zip
This is the main app used in the basic GWT section. It is built as an
Eclipse
project that assumes you have GWT installed in C:\My
Documents\GWT\gwt-windows-1.4.62. The Eclipse project links to several
files in the GWT installation directory, so it will not run out of the
box if you have GWT installed in a different location. If you have GWT
installed in a different location, you could try importing gwt-user.jar
and junit.jar into your app. But perhaps the easiest approach might be
to make a new project and copy the sample code to the new project.
For
example:
Use projectCreator and applicationCreator
to build a GWT Eclipse project with this name, as described in detail
in the tutorial.
Go to the sample code here, navigate to the src folder,
select everything under it (coreservlets, coreservlets.client, etc.),
and select Copy.
Go to your new project, navigate to the src folder,
delete everything under it, right-click on src, and select Paste.
GwtTestProject.zip
First "hello world" app used in the basic GWT section. This is simply
what you get when you run projectCreator and applicationCreator, with
no changes whatsoever.
The Google Web Toolkit (GWT): Widget Event

Main
class implementing listener interface, Named inner classes, Anonymous
inner classes, Basic widgets and their associated events, Pushbuttons
and related widgets, Checkboxes and related widgets, Listboxes and
related widgets, Textfields and related widgets. Source code
The following apps assume you have GWT
installed in C:\My Documents\GWT\gwt-windows-1.4.62. See installation
directions in previous section.

GwtRpcProject.zip
Main app used in the RPC section. It is built as an Eclipse project
that assumes you have GWT installed in C:\My
Documents\GWT\gwt-windows-1.4.62. The Eclipse project links to several
files in the GWT installation directory, so it will not run out of the
box if you have GWT installed in a different location. If you have GWT
installed in a different location, you could try importing gwt-user.jar
and junit.jar into your app. But perhaps the easiest approach might be
to make a new project and copy the sample code to the new project. For
example:
