This chapter contains the following examples:
The scenarios shown in this chapter require the following prerequisites.
Prerequisites
The following are installation and configuration requirements:
OracleAS Adapter for SAP must be deployed to Oracle Application Server.
SAP must be configured for outbound processing. See Appendix A, "Configuring SAP for Inbound and Outbound Processing" for more information.
Oracle BPEL PM Server must be properly configured and running.
Oracle JDeveloper must be properly installed.
|
See Also: Oracle Application Server Adapters Installation Guide |
The examples in this chapter present the configuration steps necessary for demonstrating service and event integration with SAP. Prior to using this material, you must be familiar with the following:
How to create a J2CA configuration, as BPEL PM is only compatible with the J2CA Connector. See "Creating a Configuration for J2CA" for more information.
How to configure OracleAS Adapter for SAP for services and events using Application Explorer. See Chapter 2, "Configuring OracleAS Adapter for SAP" for more information.
|
See Also: Oracle BPEL Process Manager Developer's Guide |
Adapter integration with Oracle BPEL Process Manager is a two-step process:
Design Time: OracleAS Adapter for SAP is configured in Application Explorer for services and events, as described in Chapter 2, "Configuring OracleAS Adapter for SAP". Integration logic is modeled using JDeveloper.
Runtime: After you deploy the BPEL process you designed in JDeveloper, you can test your service configuration or see newly received events in the BPEL Console.
This example demonstrates SAP service integration. It describes design-time, followed by runtime configuration.
Before you design a process for SAP service integration, you must generate its respective WSDL file using Application Explorer.
Generating WSDL for Request/Response Service
Perform the following steps:
Start Application Explorer and connect to a defined SAP target (a J2CA configuration).
See "Defining a Target to SAP" for more information on defining a target and connecting to SAP.
Expand the SAP target to which you are connected.
Expand Remote Function Modules, Financial Accounting, 0002 -- Company Code Business Object, and then select BAPI_COMPANYCODE_GETDETAIL.
The following image shows a connected and expanded target.
Right-click the BAPI_COMPANYCODE_GETDETAIL node.
The following menu is displayed:
Click Create Outbound JCA Service (Request/Response).
The Export WSDL dialog box is displayed.
Click OK.
You can now design a BPEL process in JDeveloper.
