### WebLogic service advertisement protocol (WSAP)

Used within WebLogic to bind and unbind objects in the replicated, cluster-wide JNDI tree. WSAP allows WebLogic Servers to dynamically join and leave a cluster; it tracks which services are available in the cluster, and it also mediates conflicts for services offered at the same node in the cluster-wide JNDI tree.
