Why do I get a class not found exception for RemoteIpValve?

Issue

• My application would like to retrieve the Scheme, which is "https" but it return "http" so I have added the following to my Apache Proxy configuration:

    RequestHeader set X-Forwarded-Proto "https"

• I have then edited jboss-eap-5.1/jboss-as/server/default/deploy/jbossweb.sarserver.xml to have the following valve:

    <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIPHeader="X-Forwarded-For" protocolHeader="X-Forwarded-Proto" />

• But when I start the JBoss, the console output class not found of "org.apache.catalina.valves.RemoteIpValve", I tried this setting in Tomcat 7, it work!
