How to host my web app in my computer?

Hi;

I developed a web application in my computer using tomcat, servlet and jsp. Then I want to host it from my computer. And I took a web address, then the host company gave me dns names and ip addresses, but I did not buy any host service, because I want to make it in my computer myself. Now How can I set these dns names and two ip addresses to my computer's ip and port number 8080 for my application? Is there any setting in the tomcat web server or any setting in the operating system for it?

The port must be set in tomcat (look at the server.xml file). The dns set up and the ip address must be set within the operating system and how you do it depends on you operating system. So without this information no one can help you.

go into your tomcat config file and change the listening port from 8080 to just 80 (which is the default for browser requests).

then change your dns to point to your IP address (helps to get a static IP from your internet provider).

that should be all you need
