You're telling JSF to use Facelets as view technology, but yet you're actually using JSPs as views. This is not going to work. Facelets is the successor of JSP and you should choose to use the one or the other.
Assuming that you just want to use JSPs, then you should remove the <view-handler> from the faces-config.xml , also remove javax.faces.DEFAULT_SUFFIX param from web.xml and preferably also remove the ConfigureListener declaration from web.xml .
Or if you actually want to use Facelets (recommendable!), then you'll need to configure Facelets and rewrite your JSPs to XHTMLs as per this Facelets developer guide .
