HTTP is the primary communication protocol that is used for exchanging data with the SLD. This applies to communication routes between the following:
· Web-based UI and the SLD server (see Configuring the Use of SSL on the SAP J2EE Engine)
· Clients that use the Java API for SLD and the SLD server
· J2EE data suppliers and the SLD bridge
· SLD bridge that distributes system data and the remote SLD server
To secure these communication routes, we recommend that you use HTTPS.
To supply data to the SLD that originates from a system other than a J2EE or ABAP system, the executable sldreg is used. The sldreg sends data in XML format using a predefined DTD. For this purpose it uses an HTTP connection, as shown in the figure below:
For example TREX, SAPOSCOL, etc. generate such an XML and register themselves at SLD via sldreg.
For more information on sldreg, see SAP Note 733476.
