Appeared Google App Engine SDK for Java. Early look.

It seems in Google App Engine Java support appeared. Now I open the documentation and see that the dock appeared in Java. An SDK is also available.

Doc: http://code.google.com/appengine/docs/java/gettingstarted/ .
SDK: http://code.google.com/appengine/downloads.html#Google_App_Engine_SDK_for_Java .

Went to watch.
