What is happening is the home.jsp is not being displayed. When I type in the URL, the pages displayed, the JSPs display correctly. When clicking the link to create new, edit, or delete contact the URL is shorten.
http://localserver:8080/myproject/listContact works fine.
clicking on edit link:
http://localserver:8080/editContact?id=1 Gets a 404 error
