Simplest thing to do would be to test remote java app from a full fledged
workstation.  So, something along the lines of: (on debian/ubuntu based
systems):

1) Going into System->Administration->Login Window, and going to the "Security"
   tab, and clicking off "Deny TCP connections to X server" (You'll want to
   turn this back on later, but for now, we'll want it.)
2) Restart your gdm (either reboot, or invoke-rc.d gdm restart)
3) Log in, open up an X term, and type "xhost +" (disable X security,
   temporarily)
4) ssh to the box with the java app.
5) export DISPLAY=<ip address of the box you logged in on>:0, so, f'rinstance:
   export DISPLAY=192.168.0.112:0
6) start the java app.  It should then open up on the local display.

If the speed's fine, then there's something wrong with LTSP.  If the speed
sucks still, then that java app doesn't like being run remotely.

I know java apps DO work with LTSP5, since I'm running a 3270 terminal
emulator app here at Legal Aid, and it works fine on my thin clients.

Through many years of hard, bitter experience, I'd consider java not working at
all to be a wonderful, beautiful blessing.  But that's just me.

Cheers,

Scott
