The Problem is, that the awt-Classes need a running X-Server (i.e. the
native peer) in order to have a graphic context to render into; this is
because complicated operations (like font rendering) is done there.
So you've to run a X-Server on that machine (or on another machine), and
set the DISPLAY-Environment Variable appropriately (The error above
implies, that the VM tries to use the localhost).
Since the X-Server is protected against anyone who is not the current user
of the X-Server, you've to allow the X-Server access with the
xhost-Utitlity:
xhost +<servername>
replace <servername> with the name of the machine the JServ-VM is running.
good luck,
