  First of all, "Google Web Toolkit (GWT) is a development toolkit for building and optimizing complex browser-based application." The purpose of this toolkit is to make possible productive development of high-performance web applications without the developer having to be an expert in browser quirks, XMLHttpRequest, and JavaScript. It's open source and completely free as well. In this toolkit, it contains SDK and Plugin for Eclipse so that we can use Eclipse as the editor to develop web application we want. The steps of installation will be illustrated as follows.

  1.Setup Eclipse:
     Downloading Eclipse from official website. Normally, I will choose Eclipse IDE for Java EE Developers as my IDE because I prefer to use this tool to develop C or C++ on Mac. Extracting zip file directly when the downloading finished.

  2.Get Plugin for Eclipse (including SDKs)
        There are two ways to get Plugin for Eclipse, one is downloading from download page of GWT, another one is installing Google Plugin for Eclipse via a link such as http://dl.google.com/eclipse/plugin/x.x. The "x.x" is the version of Eclipse, such as 4.3 for Kepler and 4.4 for Luna. According to the user guide of configuration Eclipse, we need to use Install dialog to install this plugin. The steps of installation are as following:

    I. To choose "Install New Software".

    II. Checking "Google Plugin for Eclipse(required)" and clicking "Next" button to complete the installation.

    The Eclipse needs to be restarted after installation. When the Eclipse restarted, we can use it for developing web application with GWT.
