port number in url

Hello Everyone,

I have developed a web application using jsp and servlets with tomcat server. the application is working fine in local network, but when i run in the browser the url is displaying the port number(http://local_ip_address:8080/application_folder/starting_jsp ) which should not happen.even when i specify the IP address should i need to give the port number.
I want this application to run in IIS server also, so i came to know that i should download jspisapi.dll and include it in IIS configuration to run jsp.

please help me in this regard at the earliest.

I'm confused.

the application is working fine in local network, but when i run in the browser

In the local network you're running it in a browser too, right? You can run the server with any port you like, and the URL will reflect that. Port 80 is most common, because -being the default port- you can leave out the port number.

This has nothing to do with the kind of server you're using; using IIS (with a servlet engine of some kind) works the same way as, say, Tomcat. (Although it can be hard to make Tomcat work on port 80).
