Alternative to Apache Tribes for Clustering of Axis2 Servers?

Currently i am searching for possible Clustering technologies usable by Apache Axis2开发者_如何学运维 servers. I know that WSO2 Platform uses Apache Tribes for their Servers which are based on Axis2? I want to know if there is an alternative to Apache Tribes for Clustering?

We actually also tried JGroups .. but AFAIK, it did not workout very well.

Are you guys are hitting a problem with Tribes based implementation? Within WSO2 platform, tribes has worked out very well.

We are also looking into the possibility of writing a ZooKeeper based clustering implementation.
