Thank you very much helpful mail list readers.
After checking I have verified that the problem is NOT PLJava (the code
from Mark verified that the value of HEADLESS was TRUE). PLJava is
correctly handling HEADLESS mode. But, I am still getting the error
indicated. I am going a new direction looking at a toolkit called PJA
(www.eteks.com) to see if I can get around the issue that I am having.
Sorry for the band width, but THANKS for all of your help.
Scott.
