Configuration of Secure Communication with the WebStart Client 

Secure RMI-P4 is used for communication between the WebStart client and the Integration Repository and the Integration Directory.

To enable secure RMI-P4, create or maintain the following properties in your exchange profile:

●      com.sap.aii.connect.rmi.protocol

This property contains the protocol used for RMI-P4 communication. Possible values are P4 (default) and P4S (secure).

●      com.sap.aii.connect.repository.rmiport.ssl

This property contains the RMI-P4 port number of the Integration Repository server.

●      com.sap.aii.connect.directory.rmiport.ssl

This property contains the RMI-P4 port number of the Integration Directory server.

It is a prerequisite that your Web AS is configured for SSL. More information: Configuring the Use of SSL on the J2EE Engine.

If you are working in a high-availability environment, you must also maintain the following properties:

●      com.sap.aii.connect.repository.mshttpsport

This property contains the HTTPS port number of the Integration Repository message server.

●      com.sap.aii.connect.directory.mshttpsport

This property contains the HTTPS port number of the Integration Directory message server.

It is a prerequisite that the message server of the SCS Instance is configured for SSL. More information: Metadata Exchange Using SSL.

HTTPS is then used for the communication with the message server and secure RMI-P4 is used for the communication with the WebStart client.
