Noel Raping : In this second article in the series on using the Google Web Toolkit (GWT) to build Asynchronous JavaScript + XML (Ajax) applications, learn how to build the Apache Derby database for your Web application, and use it to drive the GWT. Part 1 of this series introduced you to GWT and demonstrated how you can use it to create a rich-client front end for a Web application. This time, you'll go behind the scenes and set up the back end with your database and the code used to convert the data to a format that GWT can use. By the end of this article, you'll be ready for the front end and back end to talk to each other.
