How do I implement my Java server?

I really don't know what I'm doing, and have been trying to learn about it, but I figured I would ask for help; I have a java server (essentially the one here: http://www.akira.ruc.dk/~keld/teaching/OOP_f02/Book/chap09/BroadcastEchoServer.java, just playing around with stuff so I can learn about it), and I want to be able to run it on the internet , so with the client applet I wrote that you can embed in a browser, say, you can connect to it from different computers. I really have no idea how to go about it. I downloaded some things (Tomcat, Glassfish), signed up for google app engine, and something I think is similar specifically for Java, but I'm not really sure what I am doin开发者_运维技巧g. I am thinking I get j2ee or something? I use a mac and xcode, if that's useful at all.

Thanks in advance

Oh, the client applet is like the one from a java socket tutorial here: java.sun.com/docs/books/tutorial/networking/sockets/readingWriting.html

If your server is already working locally, what you need to do is to put it in a hosting service.

That way it can be accessible by everyone else.

That server, is an stand alone application ( that is, it doesn't need tomcat or glassfish, and certainly won't run on Google App Engine )

The only thing you need to do, is have it install it in a machine which is accessible from the internet. How to host an application is out of the scope of this site though.
