i came along the same problem some days ago. it's annoying.
you best use the X virtual frame buffer xvbf which probably came with your
linux distribution. it's a leightweight X server writing to memory instead
of a real device. it's normally used for testing.
you have to pass the DISPLAY environment variable to the JVM via
wrapper.env=DISPLAY=127.0.0.1:1
in jserv.properties. (you could use 127.0.0.1:0, but this is normally used
for the real screen on your machine, so you better use screen 1).
i also had to
- give the JVM access to the X server:
xhost +127.0.0.1
- explicitely tell the xvbf to use 8 bit colors by starting it with the
following option: (to get the colors right)
/usr/X11/bin/xvbf :1 -screen 0 800x600x8
(the resolution doesn't matter, the 8 is important)
good luck!
for me this is a bug (at least with respect to portability), for sun it's a
r'equests for enhancement' (they call it headless java). it ranges quite
high in the list of the top 25 rfe's. so to get sun to fix this problem
soon, go to their web site an vote for it!
