Hello team,
I have configured my tomee in cluster.
I have added below xml element in server.xml file for two nodes.
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="8">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
<Channel
className="org.apache.catalina.tribes.group.GroupChannel">
<Membership
className="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.4"
port="45564"
frequency="500"
dropTime="3000"/>
<Receiver
className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="4000"
autoBind="100"
selectorTimeout="5000"
maxThreads="6"/>
<Sender
className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport
className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
</Sender>
<Interceptor
className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor
className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
filter=""/>
<Valve
className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<Deployer
className="org.apache.catalina.ha.deploy.FarmWarDeployer"
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
<ClusterListener
className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>
I also created multicast.properties file in conf folder as per documentation
for multicast (UDP) discovery with below content
server = org.apache.openejb.server.discovery.MulticastDiscoveryAgent
bind = 228.0.0.4
port = 45564
disabled = false
group = default
I am trying to do the ejb look up using below configuration and I am seeing
exceptions.
Properties p = new Properties();
p.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
p.put(javax.naming.Context.PROVIDER_URL,
"multicast://228.0.0.4:45564?group=default");
Can anyone please help me on this issue.
Below is the exception stack trace : -
