Error when running the code

When I run the code, whatever code, I get this problem:

“INFO: Selected display mode: 320 x 240 x 0 @0Hz

_NSJVMLoadLibrary: NSAddLibrary failed for /libjawt.dylib

JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit

Java Result: 255”

I work on a Mac OS lion, any help, any ideas?

OSX + Java7 + LWJGL (and therefore jME) does not work, maybe that is the reason.
