Thanks a lot guys for your prompt response.
Now I face another error given below:
SEVERE: Unable to start ReplicatedContext
java.lang.ClassCastException:
org.apache.catalina.cluster.tcp.SimpleTcpCluster
at
org.apache.catalina.ha.context.ReplicatedContext.start(ReplicatedContext.java:61)
at
org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045)
at
org.apache.catalina.core.StandardHost.start(StandardHost.java:719)
The modified server.xml file looks like below:
<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="228.0.0.4"
mcastPort="45564"
mcastFrequency="500"
mcastDropTime="3000"/>
<Receiver
className="org.apache.catalina.cluster.tcp.ReplicationListener"
tcpListenAddress="127.0.0.1"
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;"/>
<ClusterListener
className="org.apache.catalina.cluster.session.ClusterSessionListener"/>
</Cluster>
<Context
className="org.apache.catalina.ha.context.ReplicatedContext"
path="/MyApp" docBase="G:\RealNetworks\apache-tomcat-6.0.16\webapps\MyApp"
crossContext="true" debug="0" reloadable="true" privileged="true"/>
Any idea guys on why is that error coming ?
Thanks a lot again for your help.
