[1] Have you tried headless mode?

java -Djava.awt.headless=true ...

[2] Try not to use 'xhost +'; it allows everyone on the
Internet to open windows on that node (definitely A
Bad Thing), absent firewalling. No doubt you have
two accounts: the one logged into using CDE, and the
one running the Java process. If you really need X
resources in the Java process (see [1], above), you
can try getting the authorization from the CDE account:

xauth list

and then create an .Xauthority file using the requisite token,
by running xauth:

xauth add xserverhost:0 MIT-MAGIC-COOKIE-1 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

where 'x' is the 32-bit hexkey listed earlier. Note that
this authkey changes every time one logs into CDE.

[3] X is slightly confusing. The display side is the *server* (it
serves up the graphics); the clients connect thereinto (usually
on port 6000 or through a secure tunnel transparently set up
by ssh), but the clients are probably running on a far more
powerful machine in many applications, especially if one has
an X terminal.

[4] xdm allows no one access until someone's logged in, AFAIK:
the rough equivalent of 'xhost -'.

It's still legal to go .sigless.

See http://developers.sun.com/solaris/ar..._graphics.html for
some better ways to do it without the problems you've been having.
