Connecting AS Java Systems to the SLD 
Each Web AS Java system has a built-in mechanism for reporting data to the central SLD (see Architecture Overview of the SLD Data Suppliers). In addition, other applications that run on the Web AS Java system can find out where the central SLD is located and use this information to connect. Bear in mind that in special cases, for example, for testing or development, the destination SLD to which other application data is reported may be different from the one to which J2EE data is reported.
Note
You must configure the SLD target even if the central SLD is running on the local J2EE Engine.
