Re: [eclipselink-users] Distributed Cache Setup 
I haven't setup cache coordination on Tomcat before, but these are the
properties I use for WLS.  If you have no JMS, then you need to use RMI, or
add a JMS server.

            <property name="eclipselink.cache.coordination.protocol"
value="rmi" />
            <property name="eclipselink.cache.coordination.jndi.user"
value="%%server-user%%" />
            <property name="eclipselink.cache.coordination.jndi.password"
value="%%server-pwd%%" />
            <property name="eclipselink.cache.coordination.rmi.url"
value="%%current-server-url%%" />
            <property
name="eclipselink.cache.coordination.rmi.announcement-delay" value="1000" />
            <property
name="eclipselink.cache.coordination.rmi.multicast-group"
value="239.192.0.0" />
            <property
name="eclipselink.cache.coordination.rmi.multicast-group.port" value="3121"
/>
            <property
name="eclipselink.cache.coordination.packet-time-to-live" value="2" />

We should provide an example deployment for cache coordination on the wiki,
please log a documentation bug for this.
