7. Dashboard contains details about your account. Click on My Applications

8. This will redirect you to below page which lists all your applications. This Application id is

needed when you deploy application on GAE cloud.

Note: You can create up to 10 applications in free edition.

Above 8 steps just help us generate application ids. As you could see, Current Version column in

above table reads None Deployed. Now we have to develop an actual application code which

then can be deployed against this application id.

9. In this tutorial, we will learn how to develop application using Eclipse IDE. And to do that, you

need to download GWT plugin for eclipse v3.6 Helios.

10.Thishttp://code.google.com/eclipse/docs/download.htmlcontains detailed explanation of how

to install GWT plug-in for various eclipse versions.

17. In Eclipse, navigate to Window -> Preferences.

18.Navigate to Google -> Web Toolkit. Click on Add

In the input box, enter the SDK location against Installation directory.

20.Click on the icon to create GWT project.

21.You will be provided with the sample Greetings application. GWT plug-in creates various files

required to develop an application. You can add/ update other files to suit your requirements.

22.To compile your code, click on .

In the GWT Compile dialog, you can customize the compilation settings and specify the set of

modules to be compiled. The Advanced link at the bottom displays text boxes where you can

add additional options for the GWT compiler and the Java VM.

23.Now we will see how we would deploy application on GAE.

To deploy your application, click on .

24.Enter your email id and password. Click on App Engine project settings

Provide application id created using first few steps. Click OK.

25.Now your application is about to get deployed on GAE. But before that, GWT plug-in checks if

all your code compiles successfully. If it does, then deployment would continue and completes

successfully. But if it does not compile, error would be thrown. You need to correct that error

and retry. If everything goes well, deployment will be successful.

26.Login tohttps://appengine.google.com/

Now you should see current version as 1 of your application.

27.Click on the version number, which takes you to your own application running on scalable,

reliable, secure Google infrastructure- GAE.
