This service is used by the SAP Web Application Server to start and stop SAP J2EE Engine 6.20, and to send information from SAP J2EE Engine 6.20 to a SAP Web Application Server. The communication between the SAP Web Application Server dispatcher and SAP J2EE Engine Cluster Manager is established using a local TCP/IP network connection. The SAP Web Application Server dispatcher binds a local port and passes the port number to SAP J2EE Engine ClusterManager using Java System Property. After initialization, the SAP J2EE Engine ClusterManager connects to this local port and the communication channel is established.
