Deployment with Warning: it has hard reference to resource com.sap.portal.u

Hi experts,

In my Web Dynpro i use IUserMappingService such as

IWDClientUser wdUser = WDClientUser.getCurrentUser();

IUser user = wdUser.getSAPUser();

IUserMappingService iums = (IUserMappingService) PortalRun-time.getRuntimeResources().getService(IUserMappingService.KEY);

IUserMappingData iumd = iums.getMappingData ("GI3CLNT001", user);

Map map = new HashMap ();

try {

iumd.enrich (map);

userid = (String)map.get( "user" );

}

catch (NoLogonDataAvailableException nldae) {

}

I added the following sharing references to my WD project:

PORTAL:sap.com/com.sap.portal.usermapping

When I deply my WD project. I get the following Warning

Result

=> deployed with warning : file:/C:/DOKUME_{1/g526466/LOKALE}1/Temp/temp31253GisaGeburtstagsListe.ear
