2397824841_f268759675 After hearing from Google, I gave a try to Java support for Google App Engine. There are tutorials available at the official Google App Engine website. I decided to write my own tutorial for you guys to create a simple “Hello World “ web application on java and run it on Google App Engine. So here it is:

You need to install Eclipse for this tutorial

Finally the rumors have been confirmed and silenced, once and for all. Google' target='_blank'>' target='_blank'>App Engine team announced on their blog:

Today, we're very excited to announce the availability of a new programming language for Google' target='_blank'>App Engine. Please welcome the Java runtime!

An application does not always use dynamic code to handle requests and there are plenty ofimage static content to be served as-it-is. For example, flash animations, images and stylesheets etcetera are all served directly without any processing required.

Google' target='_blank'>App Engine does not provide any automatic way manage directory structure and it has to be specified in your app.yaml file. This is how it’s done:

Suppose your main app directory is helloworld and you have a stylesheet named style.css in helloworld/styles. This is how you edit your app.yaml file to map all requests to /styles to helloworld/styles directory. This is actually archived by URL re-writing.

image Who says scaling is free? It does come at a cost but not what you have to pay if you were managing your own mammoth server halls. Google today announced its pricing structure for' target='_blank'>App Engine so incase your app is growing beyond your free assigned quota, you might consider taking some pennies out (yes, literally pennies!) and buy some more resources.

According to Google:

You can now set a daily budget for your app that represents the maximum amount you're willing to pay for computing resources each day. You allocate this budget across CPU, bandwidth, storage, and email, and you pay for only what your app consumes beyond the free thresholds -- prorated up to the nearest penny.

This screencast explains the process:

<a href='' target='_blank'>Google</a>_App_Engine_logo_wtxtCloud Computing is a buzz word now and every developer MUST know how to program and  deploy on the Cloud be it Google’s' target='_blank'>App Engine or Microsoft’s' target='_blank'>Azure or Amazon’s EC2. Here is a very simple tutorial on how to create Hello World (traditionally the very first app we write on anything new we learn) on' target='_blank'>App Engine.

Since it took me some time figuring out a some details which were very vaguely defined on the official text-tutorial on Google Code, so I thought of explaining it to the very minute detail for all the starters out there.

Step One (Get the Essentials):
Download Python Release 2.5.4
Download Google' target='_blank'>App Engine SDK
