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 a common complaint when using Solaris. Make sure you use nohup and see this thread

Throwable occurred: java.net.BindException: The socket name is not available on this system."*
This error message can have 2 causes:
- Java on AIX isn't supporting IPv6 properly. Fix by inserting "-Djava.net.preferIPv4Stack=true" into JAVA_OPTS 2. Your networking configuration is not correct. If you attempt to ping localhost and don't see 127.0.0.1 you need to look into your /etc/host.conf (most Unixes/Linux) or /etc/netsvc.conf (AIX) file to ensure that something like "hosts = local, bind" is present.
