Thanks, I'm trying the JConsole, but I'm not sure I'm connecting to the 
relevant process? There are two local processes that I can connect to, one 
seems to be the JConsole itself, then other has no name. If I stop the Tomcat 
service, there are still the same to processes that I can connect to!?

The -Xmx and -Xms settings should be specified in the extra memory pool boxes 
provided; the others go in the regular options box.  Keep the initial and 
maximum memory pool sizes the same to avoid heap thrashing.

Depends on the JVM version, the mode of the JVM, and the platform you're 
running on.  Easiest just to crank up JConsole and take a look.
