This section provides an overview of what gwt is, and why a developer might want to use it.
It should also mention any large subjects within gwt, and link out to the related topics. Since the Documentation for gwt is new, you may need to create initial versions of those related topics.
Download and unzip the GWT SDK. This contains the core libraries, compiler, and development server that you need to write web applications.
On Windows, extract the files from the compressed folder gwt-2.7.0.zip. On Mac or Linux, you can unpack the package with a command like:
The GWT SDK doesn’t have an installer application. All the files you need to run and use the SDK are located in the extracted directory.

sudo port install apache-ant
Create your first web application
GWT ships with a command line utility called
webAppCreator that automatically generates all the files you’ll need in order to start a GWT project. It also generates Eclipse project files and launch config files for easy debugging in GWT’s development mode.
You can create a new demo application in a new MyWebApp directory by running webAppCreator:
cd gwt-2.7.0 webAppCreator -out MyWebApp com.mycompany.mywebapp.MyWebApp
Mac or Linux
cd gwt-2.7.0 chmod u+x webAppCreator ./webAppCreator -maven -out MyWebApp com.mycompany.mywebapp.MyWebApp
webAppCreator script will generate a number of files in
MyWebApp/, including some basic “Hello, world” functionality in the class
