7 Integration With Mediator Service Components in the Oracle SOA Suite

This chapter describes integration with Mediator service components in the Oracle SOA Suite. It contains the following topics:

The scenarios shown in this chapter require the following prerequisites.

Prerequisites

The following are installation and configuration requirements:

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:

Overview of Mediator Integration

Mediator provides a comprehensive application integration framework. Oracle Application Adapter for SAP R/3 used with Mediator enables you to seamlessly integrate enterprise software, eliminating custom code. Functional modeling, as opposed to custom coding solutions, allows for software reuse and reduces the complexity and management challenges that arise over the software lifecycle. This integration model consists of two components--high-level integration logic and low-level platform services.

Adapter integration with Oracle Mediator is a two-step process:

  1. Design Time: Oracle Application Adapter for SAP R/3 is configured in Application Explorer for services and events, as described in Chapter 4, "Configuring Oracle Application Adapter for SAP R/3". Integration logic is modeled in Mediator.

  2. Runtime: The underlying platform treats this metadata as run-time instructions to enable the communication between participating applications.

Configuring a New Application Server Connection

For more information on how to configure a new Application Server connection in Oracle JDeveloper, see Configuring a New Application Server Connection.

Configuring a Mediator Outbound Process

The following example describes how to configure a Mediator outbound process to your SAP system, using a Mediator project in Oracle JDeveloper.

Samples have been provided for this use case scenario under the etc/sample folder of the Application Adapters installation.

Prerequisites

Before you design a Mediator outbound process, you must generate the respective WSDL file using Application Explorer. For more information, see "Generating WSDL for Request/Response Service".
