can anyone help me for clustering in tomcat.

here is scenario:

two tomcat servers running on same linux machine on different ports with
apache installed on front side as web server and using mode proxy ajp for
integration with tomcat. now i uncommented following tag in server.xml of
tomcat conf to enable clustering. 

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

when i start tomcat server i get following exception:

SEVERE: Unable to start cluster.
