Writing a System Resolving Service 

A portal component that contains a system resolving service is composed of two parts:

·        A java class that implements the following interfaces:

¡        IService: The standard interface for all services

¡        IDynamicSystemService: The interface for a system resolving service. This interface exposes one method, getAlternateSystem(), which returns a string that represents the PCD path to a system defined in the PCD.

·        A portalapp.xml file that defines the following:

¡        The entries in the portal registry to create in order to indicate to the system landscape service for which aliases to invoke this service

¡        The application properties that allow the service to function as a resolving service

¡        The name of the resolving service and the class within the PAR that implements the service

A portal component can contain more than one system resolving service, if the component PAR file contains several java classes that implement the IDynamicSystemService interface.

A system resolving service can resolve more than one alias, if the portalapp.xml file creates several registry entries for the service.
