Are these slaves servers that you have some degree of control over? I
ask because if so, can you just dictate that they have to run on some
known port, and then you can still get the rest of the information
dynamically.
Or, almost as good... although my idea of scanning for the port was

Right now the port was the problem. We are not using name-based virtual

There is another problem - how can you get path to tomcat root directory?
It's no

Hmm... yeah, I guess your right :) D'oh! I made the onconscious
assumption that the slave would know about itself, but if that were true
there wouldn't be any reason to do any of this, it could just send that
information to the master straight away. Sorry, I missed the obvious :)

That was my assumption; random slaves should be able to volunteer

Why cant the master server provide the information, as i assume that
some form of request is being made via a socket or otherwise to
register the client? Even if no you can still do what you need by
creating a socket or url connection to the master, and have the master
send the details back.

a bit crazy suggestion. Why don't you just parse the server.xml at
