[jboss-user] [Clustering/JBoss] - Re: HA-JNDI Namespace in JMX Console

[bstansberry@jboss.com]

You don't want an EJB to appear in the HA-JNDI namespace.  If it does, something is broken.

Each server binds a proxy for the EJB in JNDI.  The HA-JNDI tree is a replicated namespace; that means if each server bound their proxy in it, at any time only one proxy would be bound -- the one from the last server to do the binding.  That can lead to problems.

If the EJBs are deployed homogenously across the cluster, the cost of having the HA-JNDI service check the HA-JNDI tree, find nothing, and then check the local JNDI tree on the machine handling the lookup is very low.
