Preface

I wish there was more to say right here or to link to something. On to the questions...

Questions
Answers
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 here and 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 here , here , or 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 this thread
