Hi All, We are having trouble using JBC Habanero version 2.0.0.0 GA for enabling Distributed Caching. The error encountered as appearing in the log is as : Nov 2, 2007 6:00:07 AM org.jgroups.protocols.TP$IncomingPacket run WARNING: packet from a.b.c.d:45564 has different version (0.0.0) from ours (2.5.0). Packet is discarded Environment : Tomcat 5.5.20, Multicast Starting Catalina with the following option to avoid the "Problem creating sockets" : -Djava.net.preferIPv4Stack=true What I am trying to do is, use JBC for distributing cache over the Tomcats cluster established with multicasting. The steps followed were : 1. modified ip address & port for the UDP/mcastaddr and port in replSync-service.xml 2. commented off transaction manager tag in the xml, as we dont have the requirement for Transactional Caching 3. created a client that would enable/initialize the JBC caching : CacheFactory factory = DefaultCacheFactory.getInstance(); cache = factory.createCache(<url of the replSync- service.xml>); Whats happening is : 1. JGroups seems to be doing whats required as I see the following in the log : INFO: JGroups version: 2.5.0 ------------------------------------------------------- GMS: address is a.b.c.d:32838 2. And further the following is logged : INFO: viewAccepted(): [a.b.c.d:32838|0] [a.b.c.d:32838] Nov 2, 2007 6:00:06 AM org.jboss.cache.CacheImpl internalStart INFO: CacheImpl local address is a.b.c.d:32838 Nov 2, 2007 6:00:06 AM org.jboss.cache.CacheImpl internalStart INFO: JBoss Cache version: JBossCache 'Habanero' 2.0.0.GA[ $Id: Version.java,v 1.35 2007/08/01 16:52:13 msurtani Exp $] Nov 2, 2007 6:00:07 AM org.apache.catalina.cluster.mcast.McastServiceImpl$ReceiverThread run WARNING: Error receiving mcast package.

Packet is discarded 3. Is the observed error ignorable ? 4. I have not started the other node in the cluster as there are hundreds of lines appearing in the log with Packet discarded message. Have I done enough, or missing something obvious as the documents do direct us to do just the above. Best Regards, Jigyaasa_Jbosscache This email is confidential.
