Can't enable CORS in jetty

Description

Hi,
I have problem when control CORS in geoserver 2.10.1 binary. I had found any solution in OSGEO and try all these.
1.Copy jetty-servlet to lib
2. Edit web.xml
<filter>
<filter-name>cross-origin</filter-name>
<filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>cross-origin</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

But, after doing this, I can't acces web admin. It appear
HTTP ERROR: 503
Problem accessing /geoserver/web/. Reason:
Service Unavailable

Anybody got same problem and help me. Thank for your help.
