Cluster without multicast

Hi all,

I am installing openfire cluster. I downloaded coherence, but I cannot follow custerining plugin instruction. It says:

Copy coherence.jar, coherence-work.jar and tangosol.jar to [openfire]/build/lib.

But there is no tangosol. There are:

/coherence/lib: ll

coherence-hibernate.jar

coherence.jar

coherence-jpa.jar

coherence-loadbalancer.jar

coherence-mock.jar

coherence-toplink.jar

coherence-transaction.rar

coherence-tx.rar

coherence-web-spi.war

coherence-wlp.jar

coherence-work.jar

commonj.jar

je.jar

webInstaller.jar

What should I copy? I tried copy all coherence*. It starts, but prints warning about network buffers:

Is it normal?

Also, I see it uses multicast. There are some thread how to use unicast - http://community.igniterealtime.org/docs/DOC-1260 . But I am not sure if it is applicable to new coherence. How to create cluster w/o multicast?

Many thanx for help.
