ABAP Communicator Service 
This service is used by the SAP Web AS to start and stop the SAP J2EE Engine, and to send information from the J2EE Engine to the Web AS. It provides properties for connecting to the J2EE Engine, for logging process IDs, and so on.
The ABAP Communicator runs on both server processes and dispatchers.
