Hello Sanket,
In the J2EE Engine the RFC functions are implemented by the JCo RFC Provider service, which is used for processing ABAP to Java requests. A feature is provided for receiving calls from the SAP systems – this is done by registering the J2EE Engine as a RFC destination.
The JCo RFC Provider service also provides you the possibility to define particular RFC destinations to use Secure Network Connection (SNC). For more information, see
JCo RFC Provider Service - Administration Manual - SAP Library
If you want to find more help on the JCo RFC Provider service, the best will be to post your questions on the SAP NetWeaver community.
Regards,
Donka Dimitrova
