Can not display pages when I run on tomcat

Question

I have a maven webapp project which generates a .war file. I deployed it in tomcat 6 and it displays: page not found for the ìndex.jsp and a white page for the login.jsp.

And did not get any problems in the tomcat history files and also in the file log.xml under my D:\

I tried in IE and Firefox.

Some suggestions will be the welcome.

EDIT

my web app structure :

my web.xml :

    <?xml version="1.0" encoding="UTF-8"?>
