why do I need port 8080 after localhost?

Question

I've just downloaded a java application called "test-app" that I obtained from http://www.coreservlets.com/Apache-Tomcat-Tutorial/tomcat-7-with-eclipse.html and I setup tomcat 7 in eclipse. When I started the server I navigated to http://localhost/test-app and got a page could not be found error, but when I went to http://localhost:8080/test-app/ the page came up correctly. Why is this occurring? The tutorial I'm following states that I should be able to navigate to the page without the 8080.

I believe port 8080 is the default port for tomcat installations. There should be a file called conf/server.xml which you can change it from 8080 to 80 .

Look in server.xml for this line:

 <Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

And change Connector port="8080" to Connector port="80"
