RE: debug java program on AS400(debug tomcat)

I am able to start my Tomcat server on the AS400 by
running the startup.sh script, which I have modified
to call the catalina startup script with the jpda
debug option as follows:
  exec "$PRGDIR"/"catalina.sh" jpda start "$@"

However, my Tomcat starts on port 8080 (the default
port value specified in the /conf/server.xml file),
but the catalina.sh script defaults jpda to port 8000.
Shouldn't they both be pointing to the same port, or
does jpda need to be on a separate port as the tomcat
instance? Either way, my Eclipse IDE fails to connect
to the VM when I try all the possible combinations.

BTW - I read somewhere that Tomcat 4.1.29 had a
problem with remote debug capability... is anyone
aware of this? Does anyone have a working remote debug
setup from an IDE to a Tomcat 4.1.29 server on an
AS400? Maybe I should try going down to 4.1.27 or up a
notch?

Help!
