Java GUI Applications & NCD Terminals

There is problem running a java GUI based application on the NCD terminals on campus

The problem is with the old version of the NCD software (3.x) running on the NCD terminals

Reports are that version 5 of the NCD software fixes the problem, however NCD does not support the version of the terminals in BAM and in E301. A few terminal in the library can run version 5

This does not affect applets running in a browser, but does affect applets running in the appletviewer

You must type
   xstdcmap -all" 

at the shell prompt before you run a java application that uses AWT and have it display on an NCD X-terminal in the BAM labs

This does not work with some window managers like fvwm

In JDK 1.1.5 and 1.2b2 the window coordinate system on the NCD is off by 10-30 pixels
You need add 10-30 pixels to the y coordinate system so that the top of the window is accessible
