If TechCrunch and GigaOm are right, then GAE should get Java around the end of May.
Google will soon announce comprehensive support for the Java programming language on its Google App Engine (GAE) offering. We are trying to get more details. Rumors of such a development emerged last year, but we can now confirm that it is going to happen. We have have confirmed the news and expect the announcement later this spring, perhaps at the much-vaunted Google I/O event on May 27-28th at the Moscone Center in San Francisco. A Google spokesperson declined to comment.
What does this mean? GAE currently is a Python-only app hosting environment and Java has been one of its most-requested features. Google’s support would help Java hosting get a mainstream push. Thus far most people have pushed PHP, Perl or Rails-related hosting services. I wouldn’t be surprised if Google uses a variant of its own Java VM, code-named Dalvik, which is currently being used in Android and Google Mobile OS. Dalvik is a non-Sun-licensed Java environment.
Which would make me very happy. Python is ok, but I much prefer {}’s to whitespace :)
