There is no problem getting the host name of the mcahine that the Servlet is
running on just call:
java.net.InetAddress().getLocalHost().getHostname();
Course this isn't going to solve your problem if you the machine you are
running on has more than one IP address (I believe it will always return the
first IP address) or if it is set up with virtual hosts.
As for getting the port number I can't think of any API that would give you
that info.
Why not just use a property file that your servlet read on startup that
contained the info you require?
