Cluster error when starting up web application

[Aadi Deshpande]

Hi,

I just got Tomcat 5.0.19 and after setting up the new delta based 
cluster manager, i get this during the startup my application :

SEVERE: Session event listener threw exception

As far as I can tell, it's happening when I request a page that has the 
webwork2 RequestLifecycleFilter set for that url pattern.  The doFilter 
function creates a HttpSession if none exists, which I assume calls the 
SessionLifecycleListener.sessionCreated(), but for some reason, it seems 
like the session is being invalidated prematurely..

Here's the relevant piece from my web.xml :
   <filter>
       <filter-name>container</filter-name>
       <filter-class>
           
com.opensymphony.webwork.lifecycle.RequestLifecycleFilter</filter-class>
   </filter>
   <filter-mapping>
       <filter-name>container</filter-name>
       <url-pattern>/*</url-pattern>
       <!-- modify appropriately -->
   </filter-mapping>
   <listener>
       <listener-class>
           
com.opensymphony.webwork.lifecycle.SessionLifecycleListener</listener-class>
   </listener>
   <listener>
       <listener-class>
           
com.opensymphony.webwork.lifecycle.ApplicationLifecycleListener</listener-class>
   </listener>

and from my server.xml file, taken pretty much verbatim from the default 
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="224.64.64.128"
               mcastPort="45600"
               mcastFrequency="500"
               mcastDropTime="3000"/>
    <Receiver
               
className="org.apache.catalina.cluster.tcp.ReplicationListener"
               tcpListenAddress="auto"
               tcpListenPort="4060"
               tcpSelectorTimeout="100"
               tcpThreadCount="3"/>

           <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>

Anyone know what's going on? Or can provide some insight into what I may 
be missing?

Thanks for any info.
