VRaptor2 on Google App Engine

With all the recent excitement about Google supporting Java for the App Engine platform, I’m proud to say that VRaptor2 just works, out-of-the-box!

All you have to do is copy the required jars that come in the vraptor distribution, configure the VRaptorServlet (or VRaptorFilter) in web.xml and enable session support in the appengine-web.xml:

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
	<application>...</application>
	<version>1</version>
	<sessions-enabled>true</sessions-enabled>

	<!-- ... -->
</appengine-web-app>

Being able to use my favorite Java Web MVC framework, to develop and deploy applications to Google’s cloud infrastructure, is really nice.
