Java processes/threads

[Jan Bares]

Hi,

when I run JBoss, all the processes such as Tomcat, SQL server and so on
appears as threads of a single process. How does Java manage separation
between them (in OS thread the memory is shared between threads)? How are
Java threads mapped to OS threads (one Java thread = one OS thread)?
Is there a tool, that can show me which Java threads belong to Tomcat, which
belong to SQL Server etc?

I would be glag if you can point me to some documentation about this topic.
I know that ClassLoader is the key to this question.

(I am C++ professional working on Windows)
