So, let’s start by creating a new Java project in Eclipse. I created the project in a folder called NewsClient in the gwt directory (C:\gwt) of my system. Then I added a source folder named src in the project and added necessary packages to it so that the structure looks like the one shown in Figure 1-5. ) I did not add the server package at this time because the application is not making any RPC calls to server-side logic as of yet. You will learn about RPC (server-side code) starting in Chapter 4 in the book.

The following sections will discuss these components. Development Tools Explained GWT provides two core tools to assist in the development of an application.

Deferred Binding Reflection and dynamic class loading are very powerful concepts used in the Java language, and they open the door to a number of advanced techniques while programming. This section shows how these concepts are used within an example and then relates them back to the GWT.
