I just wanted to be clear. :-) A JVM is a regular UNIX process, I see no reason why it shouldn't
be able to close it's controlling terminal. Or ignore loosing one, for that matter. I have
started Tomcat from a terminal with "catalina.sh start" and it shows on "ps -A" as:

15532 ??       S        8:34.29 /usr/opt/java130/bin/alpha/native_threads/java -classpath
/usr/local/java/tomcat-4.01/bin/...

So, it can survive even without "nohup".

Yes, effectively it will do the same thing as "start"

Nix.
