When I run ps (on Linux), why do I see my java process a bazillion times!

Linux implemented threads as processes. Due to other gory details that is beyond the scope of this FAQ - the ps command doesn't work correctly with respect to threads. You can get more gory details [http://www.onlamp.com/pub/a/onlamp/2002/11/07/linux_threads.html here] and [http://pauillac.inria.fr/~xleroy/linuxthreads/faq.html#D here] .

How do I run without an X server and still get graphics?

You either need to run headless or run an alternate X-server. Some more information can be found [http://marc.theaimsgroup.com/?t=104803047600003&r=1&w=2 here], [http://marc.theaimsgroup.com/?l=tomcat-user&m=102335321103262&w=2 here], or [http://marc.theaimsgroup.com/?l=tomcat-user&m=101614645312259&w=2 here]. Or if your are using a JVM 1.4 or better, you can use the system property java.awt.headless=true

Tomcat dies after I log out!

This is common complaint in Solaris. Make sure you use nohup and see [http://marc.theaimsgroup.com/?l=tomcat-user&m=104809785114238&w=2 this thread]
