Java Server

I need help in calling the Java Chat Server out. I already created a java
based chat room, a very simple chat room. However, it works well in the local
area network where let say my computer will act as the server, where I will
use the function in jdk to run the server file. However, how I'm going to
run the server if I wish to put the chat room in internet? I can't online
all the day, right? I really need help in doing that for my project. Hope
anyone who knows can help me!
Thanks anyway!

Hi ,
U havent specified what exacly u have used to make the chat server. I
assume that u must have used the sockets to make the chat server . On a lan
u make one computer as a server , but in Internet the things r a bit different
. There r servers , such as JAVAWEB server which run continuoulsy .. then
u use Perl or Servlet techology to make ur application . So u have to learn
all that . For knowing servlet technolgy u can refer to Jason hunters book
ie by Oreilly publications . I wont b able to to explain in details regarding
that , but as for now u cannot run ur application on internet .U can mail
me for any more info ..
