When I try to goto my web page
(http://localhost:8080/E3/common/CustomerInq/index.faces) I get a blank
screen.
However, if after getting the blank screen I goto the login page
(http://localhost:8080/E3/login2.jsp) and type in a correct login page then
I will get redirected to the CustomerInq/index.faces page correctly.

 

This is a snippit of my web.xml...
