often i write my application just with JSF, any way this time i must make Web application (JSF + Maven)

The problem is that my JSF don't run with maven, all my JSF codes are 100% correct also they work very well with normal Dynamic web application (without maven), but with maven i always got the following error message:
HTML Code:
HTTP Status 404 - /JavaServerFaces/hello.jsf
I tried to get tutorial from internet JSF 2.0 hello world example and do the same step by step, but still the same result Status 404

I don't know why that happens but Maven works very well with JSE applications also works without problems with JSP application (problems just with JSF)

I use Eclipse as IDe and Tomcat 7 as server

any ideas???
