Web.xml error in RESTFUL web application using Apache CXF

I have to build a RESTFUL web application using Apache CXF. My application doesn’t work when i edit web.xml like this .





However, when i delete my edits and go back to first version of web.xml , the application works.I checked out many sources to see if my web.xml notations were wrong but the configuration looks right.In addition to this situation , If i edit web.xml in any way, the web application does not work. Any help would be appreciated.
