Hi,
I doubt that its Java related – if it was Java I would expect all your GUI’s to fail not just one.
Can you open the files that form the inpuit/output to your xlates i.e. HL7, HRL’s FRL’s etc.? Are you seeing any other symptoms or is it just when you try opening xlates?
Can you create new xlates or is just openinig existing ones?
