Oracle Application Server Adapters Installation Guide

Configuration Steps

The examples present all the configuration steps necessary for demonstrating service and event integration with SAP. See the following for more information:

  1. Configure SAP for outbound processing. See Appendix A, "Configuring SAP for Inbound and Outbound Processing" for more information.

  2. Create a J2CA configuration, as BPEL PM is only compatible with the J2CA Connector. See "Creating a Configuration for J2CA" for more information.

  3. Configure OracleAS Adapter for SAP for services and events. See Chapter 2, "Configuring OracleAS Adapter for SAP" for more information.

SAP Event Integration

This topic illustrates how OracleAS Adapter for SAP integrates with SAP to receive event data. The procedures describe design time and runtime. The example demonstrates how OracleAS Adapter for SAP integrates with SAP to receive event data. In this example, an SAP event occurs when a customer record is added to an SAP system.

The design time and runtime procedures are outlined in the following sections.

Design Time

Creating a Channel

You must create a separate channel for every inbound J2CA service and select that channel when you generate WSDL for inbound interaction using Application Explorer.


Note:

If more than one inbound service share the same channel, event messages will not be delivered to the right BPEL process.

To create a channel:

  1. Start Application Explorer and connect to a J2CA configuration.

  2. In the left pane, expand the Events node.

  3. Expand the SAP node.

    The Ports and Channels nodes appear in the left pane.

    The Add Channel dialog box is displayed.

    Add Channel dialog box
    Description of the illustration addchanneldialog.gif

    Perform the following steps:

    1. Enter a name for the channel, for example, SAP_Channel.

    2. Enter a brief description (optional).

    3. From the Protocol list, select SAP Channel--App Server.

  5. Click Next.

    The Application Server dialog box is displayed.
