change project url

i thought changing the url of the webapp was as simple as changing the field in the web.xml.
ie. changing AddressBook to AddressBook2
would change the url to http://localhost:8080/AddressBook2.
but this doesn’t work, the app only loads with the original url http:localhost:8080/AddressBook.
how do you change the url of webapp?


figured it out.
in eclipse, you have to “Open” the server , click the modules tab and then you can change the path.
