 Registering a DestinationLocate this document in the navigation structure

Use

The J2EE Engine provides the function to be called from the Web AS. This is done by registering the server as an RFC-destination. This registration is done using the JCo RFC Provider service, which processes the calls from the Web AS.

To parse the function-calls from the Web AS correctly, the SAP JCo (Java Connector) needs a repository, which must be created in the JCo RFC Provider along with the new destination.

Procedure
  1. In the J2EE Engine Visual Administrator, choose Server → Services → JCo RFC Provider → Runtime.
  2. Use the RFC destination pane to specify the destinations parameters:
    1. Choose the Program ID field and enter the program ID of the JCO server which is configured at the gateway service.
    2. In the Gateway host field, specify the host of the gateway, through which the requests are passed.
    3. In the Gateway service field, enter the gateway service that will receive requests for handling JCO functions.
    4. Choose the Number of processes (1 to 20) field and specify the number of JCO Servers simultaneously running with the same Program ID.
  3. Use the Repository pane to define a repository parameters:
    1. In the Application server host field, specify the host of the SAP Web AS for the repository.
    2. In the System number field, enter the system number for the client connection to the repository.
    3. Choose the Client field to specify the client used to connect to the repository.
    4. Choose the Language field and specify the language for the specific connection (for example - En).
    5. Choose the User field and enter the user name for the client connection to the repository.
    6. In the Password field, enter the user password for the client connection to the repository.
  4. Select the Local bundle indicator, if you want the bundle to run only on the current cluster element.
  5. Add the destination as a bundle.

    After the RFC destination is registered along with the defined repository, choose Set in the bottom of the right-hand pane to add it as a new bundle.

    Note

    The bundle program ID must not figure in the list of RFC destinations.

Managing the Available RFC Destinations

  • To change the bundle's properties, select it from the list of available destinations or type its program ID in the corresponding field, change the desired field(s), and choose Set.
  • To remove a bundle, select it and choose Remove.
  • Starting and stopping of a bundle is done using Start or Stop.
  • To import a bundle, use  on the Runtime tab toolbar.
