Which SharingReference I need to add at a portal service for these packages

Hello,

I have written a portal service, not at the Dynpro, environment which uses these imports:

com.sap.tc.webdynpro.progmodel.api.IWDNode;

com.sap.tc.webdynpro.progmodel.api.IWDNodeElement;

com.sap.tc.webdynpro.services.sal.url.api.IWDCachedWebResource;

com.sap.tc.webdynpro.services.sal.url.api.WDURLException;

com.sap.tc.webdynpro.services.sal.url.api.WDWebResource;

com.sap.tc.webdynpro.services.sal.url.api.WDWebResourceType;

Which SharingReference do I need to add in order for this to be recognized from the service?
