And the second jonas stop at the starting point...
The tomcat port won't be the only problem that you will get…
In fact as jonas is a complete set of applications, it start many network services that can
come into conflict in case of several instance...
You should get more informations on JOnAs to allow several instance of Jonas on the same machine.
Sorry for this little help...

PS: The tomcat configuration file is in JONAS_ROOT/conf/server.xml
