Back to this; time to get it done. "bstansberry(a)jboss.com" wrote : | To recognize each other the deserialized proxy and the local container need a common piece of info. | | Perhaps including the partitionName is sufficient. Including the partitionName in the container OID/ObjectName won't work, as the ObjectName is created in the EJBContainer c'tor, before any the value of any @Clustered annotation or xml config is available. So, that means the partition name needs to be independently stored in the proxy and the EJBContainer. This means adding a partitionName field to the clustered proxy classes and to EJBContainer, and adding logic to EJBContainer.start() to resolve any @Clustered annotation. I'll add a ClusteredIsLocalInterceptor which tries to match up the proxy with the container, routing the call locally if there's a local bean from the same partition. Any objections to this?
