Sigh, I want Ruby support...but I'm building my app in Python anyways and Python isn't as bad as I thought (you get used to the indentation style and the sprinkling of "self" in methods).

  I don't see why any of the JVM languages wouldn't work...
  - jamesbritt 18y ago
    Indeed. I plan on giving jruby a shot.

  Heroku?

Ha, then you could run AppJet on Google.

Anyone know if they are going to use some sort of existing Java MVC framework or if they're going to create their own?
- scorpion032 18y ago
  Obviously they are going to base it upon a famous Java FW, but do it themselves.

    Like GWT?
    - michaelneale 18y ago
      GWT doesn't really require anything on the server (it doesn't have to even be java/JVM), so its kinda already supported for folks that want to use it for the front end.
      - huherto 18y ago
        Therefore, if you use GWT you don't need an MVC framework for Java anymore.
        michaelneale 18y ago
        correct. You could make do with servlets. Or if you want to use JSON you could use anything.

  Hopefully they create their own. There's not one java framework I think is nice.

I hope OSGi is supported!
- jwilliams 18y ago
  You'd have to assume that it would have to be... otherwise it would be a god-awful mess...
  - trapper 18y ago
    Unlike eclipse of course, which isn't plagued by classpath issues and runtime errors, causing plugin authors pain, users pain (which plugin version, will this plugin break that plugin etc). Osgi couldn't be behind that could it? Great in theory. Eye stabbing in practice. Just like spring compared to guice.

I am keen on the other question mentioned in the post. "Whereas Cpp seems to be the most popular language by Google code Jam statistics, How come Java turns out to be the supported one, based on popularity?"

  In the cloud you want to share resource to drive down costs - that means hosting multiple requests in one process. To maintain security/stability in such case the language must lend itself to sandboxing either by code verification or running in a VM. Hence Python and Java.
