Well, I don't believe you can have multiple applications/programs
listening on one port.  But when you use servlets, you don't write
applications that listen directly to a port.  That is the job of the
web server, and based on the request it sees on that part, it will
decide what to do with it, which may involve passing it on to
(eventually) some particular web application/servlet.  And you can
very well develop some new web application/servlet, and by putting
appropriate directives in the appropriate configuration file(s), have
the web server pass appropriate requests to it (you can see how
important being appropriate is).
