Google's appengine supports Java now!

Google just rolled out Java support for their AppEngine, which previously only supported Python. This is great news since it opens the whole AppEngine to Java programmers (or at least those of us who know Java better than Python;). They say it’s an early release, but it’s a step in the right direction!

I’ve downloaded the Eclipse plugin, installed it, and generated both an GWT and plain JSP for my site. Creation was easy, uploading was a snap, and running it worked well. There are only two complaints/notes:

1. Installation of the Eclipse plugin froze the Eclipse app twice. I killed the Eclipse process and re-tried the installation. It worked the third time. No problems since.

2. Versioning is weak. I tried to upload a new app and label it version 1.1, but the upload failed. It only worked when I provided an integer value. Seems silly that versions have to be integers. Oh well…

Otherwise, works great. I look forward to learning the new features.
