HAJNDI

public class HAJNDI extends Object implements org.jboss.ha.framework.interfaces.HAPartition.HAPartitionStateTransfer, Serializable, org.jnp.interfaces.Naming
This class extends the JNP JNDI implementation. binds and unbinds will be distributed to all members of the cluster that are running HAJNDI. lookups will look for Names in HAJNDI then delegate to the local InitialContext
