If you run Tomcat as a "service" (whatever that means under Linux),
then it probably runs as some user other than "you" (the one who owns
the X environment). When you run it as "you", then you get access to X.

It would work as a service if:

1. X starts before Tomcat
2. X is configured with "xhost +" for whatever user it is
3. Tomcat's startup can have the proper DISPLAY variable set
(localhost:0?)
