Define the location of the files in the SAP Web Dispatcher and the AS Java:
configure the wdisp/J2EE/group_info_location and wdisp/J2EE/url_map_location parameters in SAP Web Dispatcher's profile.
configure the GroupInfoLocation and UrlMapLocation in the HTTP Provider service in AS Java.
Open the SAP NetWeaver Administrator.
Open the HTTP Provider service running on server process.
Add the corresponding URLs as values of the GroupInfoLocation and UrlMapLocation properties.
Save the settings of the properties.
