Problems deploying Grails (from STS) to cloudfoundry

[Robby]

Hi all,

I'm hoping someone can help me with this. The steps I'm doing USED
to work when I was first playing with cloudfoundry last month.

Basically: I create a new Grails app (using STS), create a fast
controller / domain class - setup scaffolding and run-app (locally) -
works like a charm.

I deploy the same grails app to cloudfoundry (either the micro vm,
or the github installer on a rackspace ubuntu 10.04) and I am getting
the same error:

Based on the error:

This appears to be an issue of compiling and then deploying with incompatible Java versions: http://stackoverflow.com/questions/8055418/grails-spring-security-plugin-plugins-missing

Make sure you're compiling with Java 6 since that's what vcap uses.
