   *              - this is default activation policy

   *              - session times out unless called again within timeout period
   *              - runs on thread dedicated to calling client
   *   Singleton  - remote object created in session on first call
   *              - session times out unless called again within timeout period
   *              - runs on one thread so all clients see same instance
