Hi Sivaram,
I had something similar but it nolonger works in 5.0.30-beta ... it
seems to need to be in a format like below. This at least tries to start
even if it NPEs.
<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
useDirtyFlag="true"
debug="10"
serviceclass="org.apache.catalina.cluster.mcast.McastService"
mcastAddr="239.192.42.4"
mcastPort="45564"
mcastFrequency="500"
mcastDropTime="3000"
tcpThreadCount="6"
tcpListenAddress="auto"
tcpListenPort="4001"
tcpSelectorTimeout="100"
printToScreen="false"
expireSessionsOnShutdown="false"/>
<Valve className="org.apache.catalina.cluster.tcp.ReplicationValve"
filter=".*\.gif;.*\.js;.*\.jpg;.*\.htm;.*\.html;.*\.txt;"/>
