screwed up setting up app runtime....

[webclimber]

So I just got the account activated and created a couple of entries
for applications but it seems that I (unknowingly) selected python as
the runtime but I just want the java version ...

Is there anyway to fix this ? Or did I just loose those two names
forever ? Is it possible to change the runtime ? (I know delete is not
allowed).

You can't set the runtime at the application level; each version will
have whatever runtime was set the last time you uploaded.

If you're seeing an Invalid Runtime message, it's because you're not
approved for the Java version yet (it's still in limited preview).

Wooble is absolutely right -- once your account is activated, you can deploy both Python and Java applications to a given ID. You can even deploy a Python application to one version and a Java application to a second version of the same application!

For more information on the error you're likely seeing and a sign-up form for the Java runtime, click the following link. You should get an email when your activation is ready.
