I have put the ipv6 address in two places in server.xml. Those are: <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.8" bind="fc00:10:112:107:0:0:0:236" port="45564" frequency="500" dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="fc00:10:112:107:0:0:0:236" port="4200" autoBind="100" selectorTimeout="5000" maxThreads="6"/> exception that i am getting is: Apr 3, 2009 11:32:34 AM org.apache.catalina.tribes.transport.ReceiverBase bind INFO: Unable to bind server socket to:/fc00:10:112:107:0:0:0:236:4299 throwing error.
