My apologies again but I have not made any progress on this problem. Is there perhaps a better forum I should be using at this point? I did make one discovery. It appears that although the application works in Eclipse when I try to export it to a runnable jar using the Eclipse wizard, the resulting jar fails as well. It seems to me that the problem is not ant specific but something in the app build per se.
