Configuring the SLD Client
The SLD service provides every Java application with the option to generate an SLD client for accessing an SLD server. The SLD client is common for all applications that are using it and therefore plays the role of a standard SLD. Changing the data for the SLD client may have an effect on many applications. We recommend that you consider it carefully.
1. To change the default SLD in SAP NetWeaver Administrator, go to Configuration Management → Security Management → Destinations.
2. Change the connect parameters in HTTP Destination “SLD_Client”

Both the sending and the receiving AS Java must be configured for Secure Socket Layer (SSL) connections before you can use HTTPS.
