Hi Tomcat user,
        I'm trying to setup a in memory session replication with tomcat.

I have:
-tomcat 5.0.24
-java 1.4.2_04
- Red Hat Enterprise Linux 3

I have two machine dl580-1 and dl580-2 with tcp/ip and multicast enabled. this 
is the cluster part of server.xml.

       <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
                 
managerClassName="org.apache.catalina.cluster.session.DeltaManager"
                 expireSessionsOnShutdown="false"
                 useDirtyFlag="true">

            <Membership
                className="org.apache.catalina.cluster.mcast.McastService"
                mcastAddr="224.0.0.1"
                mcastPort="45564"
                mcastFrequency="500"
                mcastDropTime="3000"/>

            <Receiver
                
className="org.apache.catalina.cluster.tcp.ReplicationListener"
                tcpListenAddress="auto"
                tcpListenPort="4001"
                tcpSelectorTimeout="100"
                tcpThreadCount="6"/>

            <Sender
                
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"
                replicationMode="pooled"/>

            <Valve 
className="org.apache.catalina.cluster.tcp.ReplicationValve"
                   filter=".*\.gif;.*\.js;.*\.jpg;.*\.htm;.*\.html;.*\.txt;"/>
        </Cluster>

when I try to put the label <distributable/> in 
jakarta-tomcat-5.0.24/webapps/jsp-examples/WEB-INF/web.xml
I recive in the catalina.out these errors:
