[jboss-user] [JBossCache] - Error starting cache with TCP and TCPPING

[urisherman]

Hi,
I tried running a simple program using JBossCache (both from a standalone on windows and in WLS8.1 on linux, so the environment probably isn't the issue), after I changed the configuration to use TCP and TCPPING unicasting rather than UDP and multicasting.

I took the new configuration from some example in JGroups site - 


                <TCP start_port="7050" />
                <TCPPING initial_hosts="10.106.124.239[7050],10.106.124.240[7050]" port_range="5" timeout="3000"
                	num_initial_members="2" up_thread="true" down_thread="true"/>
                
                <VERIFY_SUSPECT timeout="1500"
                    up_thread="false" down_thread="false"/>
                
                <pbcast.STABLE desired_avg_gossip="20000"
                    up_thread="false" down_thread="false"/>
                    
                <pbcast.NAKACK gc_lag="100" retransmit_timeout="3000"
			up_thread="true" down_thread="true"/>
                
                <pbcast.GMS join_timeout="5000" join_retry_timeout="2000"
                    shun="false" print_local_addr="false" up_thread="true" down_thread="true"/>
            

I got this error:

Exception in thread "Main Thread" org.jgroups.ChannelException: unable to setup the protocol stack

Any help would be appreciated, couldn't find any info about this "GET_DIGEST_STABLE" event....
