if you have a log file of a jvm crashing multiple times, jserv will give up
and dump some debugging info. from this you can glean that the only
environment variables set are the path and the classpath. In order for
display to be exported to the environment that the jvm is running in, you
would have to set it in the same place the path & classpath are set, which i
suspect is taken care of by the binary module. if there isn't such a
configure option already, you might want to patch the jserv source to take an
additional configure option to define environment variables.
