Unable to compile java code.

Hi,

Whenever I try to compile java code I get the following error.

Compilation completed with 1 error and 0 warnings in 2 sec

java: Cannot find JDK '1.6' for module 'deleteme'

The SDK is set undet Project and also the Module. I really don't know what's going on since IDEA logs/errors aren't verbose enough.

Anyone had this issue before ?

Intellij IDEA Ultimate 12 on RHEL 6.2

Thanks.
