well apparently my problem is that my cluster is not working properly. I can see the multicast broadcast messages on my network, however the objects do not seem to be replicating. The only thing I have in my logs is:
INFO: Manager[/testapp], skipping state transfer. No members active in cluster group. This displays after the delta manager starts in the catalina.out file. If anyone has any good ideas on why this is happening for me, I would be willing to try anything at this point. My NIC supports multicast. I have set the distributable element in the web.xml.

I suspect that nothing will be replicated if there is non serializable objects in there.

I have been testing session objects that implement java.io.serializable and I have not yet been able to see these objects when fail over occurs to another instance??

When we switched to clustering I was surprised at how many of my session objects I needed to add serializable to. But it was easy work and quickl done.
