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.
