Connect to R/3 with the connector framework

Dec 11, 2003 at 12:12 PM | 7 Views

Hi,

I am trying to call a RFC function from R/3 using the new connector framework instead of JCO.

However, I'm not quite sure how to create complex data type for the input parameters. I get the parameter structure but I don't know how to create the IRecordSet object to send in the input parameters record.

Any help would be appreciated.

Thank you.

Regards,

Rui Gonçalves

    Check the JCO examples.

    It is the same. Sap CF just offers the connection management.

      Hi,

      Sure...

      public static IConnection getConnection(String sapSystemAlias,

      IPortalComponentRequest componentRequest)

      throws IllegalArgumentException {

      // check if passed attributes are null

      if (componentRequest == null) { throw new IllegalArgumentException(

      "IComponentRequest object can not be null!"); }

      if (sapSystemAlias == null) {

      // use default system alias

      //sapSystemAlias = defaultSAPSystemAlias;

      }

      ILogger logger = PortalLog.getLogger();

      com.sap.security.api.IPrincipal user = componentRequest.getUser();

      Locale locale = componentRequest.getLocale();

      ConnectionProperties properties = new ConnectionProperties(locale, user);

      IConnection connection = null;

      try {

      IConnectorGatewayService connectorGatewayService = (IConnectorGatewayService) PortalRuntime

      .getRuntimeResources().getService(IConnectorService.KEY);

      connection = connectorGatewayService.getConnection(sapSystemAlias,

      properties);

      } catch (Exception e) {

      logger.severe(e, "Exception while creating a connection.");

      }

      return connection;

      }

      It makes also sense to have a central method to close connections...

      public static boolean closeConnection(IConnection connection) {

      boolean succesful = false;

      if (connection != null) {

      try {

      connection.close();

      succesful = true;

      } catch (ResourceException re) {

      PortalLog.getLogger().severe(re,

      "Connection to SAP could not be closed!");

      }

      }

      return succesful;

      }

      and interactions...

      public static boolean closeInteraction(IInteraction interaction) {

      boolean success = false;

      if (interaction != null) {

      try {

      interaction.close(); // close interaction

      success = true;

      } catch (Exception e) {

      String message = "Exception closing interaction.";

      PortalLog.getLogger().severe(e, message);

      }

      }

      return success;

      }

      Regards,

      Kai
