Because GWT web applications run inside of a browser, they are limited to making requests over HTTP. HTTP is a “stateless” protocol and it doesn’t provide any facilities for tracking previous transactions. In this tutorial you will learn how to use GWT’s RPC mechanism, specifically the RemoteServiceServlet, to enable session support in your GWT application.

This tutorial will teach you how to create and use Serializable objects that can be transported over GWT’s RPC mechanism.

One of the most important pieces of the GWT framework is the GWT Remote Procedure Call (RPC) mechanism. This RPC mechanism makes it easy for a GWT application client to make a call to server-side code. GWT RPC makes it simple to get data between the client and the server. The server-side code that gets called from the client is referred to as a service. This tutorial will teach you how to build a GWT RPC Service.

The first step in writing any GWT application is setting up a GWT Project. This tutorial will introduce you to the ins and outs of GWT projects.
