Your comments above still indicate confusion on your part, and it might be good to learn more about how ports/sockets work, how web servers work, and how http works. Basically, you only have one application running (i.e. listening) on that port. That application is Tomcat. It is running as a web server. The protocol it uses to communicate on that port is HTTP, and HTTP (on the server side) involves accepting requests and sending back responses. Essentially what you have above is not two different applications, but two different requests, one for /project1/servlet/servlet.class and one for /project2/servlet/servlet.class. Now, in processing such requests, Tomcat may invoke what are known as "web applications" in the servlet sense. But those applications themselves are not running on the same port -- nor any port, for that matter. > > On Wed, 11 Sep 2002, Galbreath, Mark wrote: > > > > > As I (and apparently, Milt) interpreted the > > question, I though he > > > > What I'd say is that you answered the question he > > actually asked, > > while I answered the question he meant to ask :-). > > (I did say that he > > couldn't run two applications on the same port, but > > I also described > > how he could set up another web application.)
