Configuring Logon Groups on AS JavaLocate this document in the navigation structure

Context

Use this procedure to define logon groups using SAP NetWeaver Administrator, and then configure the internal protocol between SAP Web Dispatcher and AS Java, so that SAP Web Dispatcher retrieves information about logon groups.

Procedure


  1. Define logon groups using SAP NetWeaver Administrator. For more information, see Logon Group Configuration .

  2. Define the special HTTP URLs that SAP Web Dispatcher uses to send to AS Java to retrieve information about the logon groups.

    Specifying the URL is done using the wdisp/J2EE/group_info_location and wdisp/J2EE/url_map_location parameters in the SAP Web Dispatcher's profile.

    Note

    Make sure the URLs you specify with the two properties above do not start with the /sap/ string. In this case, SAP Web Dispatcher redirects them to AS ABAP rather than to AS Java, which is critical in an ABAP and Java system.

    Note

    Make sure the URLs you specify with the two properties above do not overlap with a URL used to request an application on AS Java. In such case, the URL sent by the SAP Web Dispatcher is handled with priority; therefore, the system does not serve requests to your application correctly.

  3. To make AS Java aware of the special URLs that SAP Web Dispatcher uses for retrieval of logon group information, you must configure the GroupInfoRequest and UrlMapRequest properties of the HTTP Provider service running on server processes:

    1. Open SAP NetWeaver Administrator.

    2. Open the HTTP Provider Service running on server process.

    3. Add the corresponding URLs as values of the GroupInfoRequest and UrlMapRequest properties.

      Recommendation

      We recommend that you use the following value to configure the GroupInfoRequest property:

      /J 2 EE/icr_groups

      We recommend that you use the following value to configure the UrlMapRequest property:

      /J 2 EE/icr_urlprefix

    4. Save the settings of the properties.

      Note

      Be aware that when AS Java receives a request containing this special URL, it returns a response with sensitive information about your cluster setup.
