Specify whether to advertise RMI objects and EJBs as supporting stateful CSIv2. Stateful CSIv2 is more efficient than stateless, requiring only a single authentication step for each remote principal. Stateless CSIv2 requires per-request authentication. Stateful CSIv2 is not required by J2EE 1.3 and so some ORBs do not support it. Stateful CSIv2 is enabled by default. This property can be changed at the object-level by changing the object's <stateful-authentication> runtime descriptor prope Enabling stateful authentication reduces authentication overhead and improves performance for remote object calls. Example: with stateful enabled, a remote client authenticates once and reuses that authentication token for multiple method invocations.
