Ásta - thanks for letting us know how you did this! I don't need to do this today, but
I'm sure I will someday!
Could you provide more details on how you did items 2 and 3 for those of us new to X
(like myself)?
Also, I don't see anything in your script that starts JServ up in Display 0 but
perhaps that what step 1 takes care of?
Thanks!
Tyler

>CLASSPATH=$CLASSPATH:/usr/local/JSDK2.0/lib/jsdk.jar
