SOA Integration - Implementing the Process Integration Business Pattern

In the scenario shown in the following diagram, the process integration business pattern is implemented using BPEL.

Trigger:

An application places a message in the queue.

Primary flow:

• The message is extracted from the queue through JMS and a corresponding JMS adapter.
  .
• A new instance of the BPEL integration process is started and the message is passed to the instance as input.
  .
• The integration process orchestrates the integration and calls the systems that are to be integrated in the correct order.
  .
• A content-based router in the mediation layer is responsible for ensuring that the correct one of the two systems is called. However, from a process perspective, this is only one stage of the integration.
  .
• In the final step, a “native” integration of an EJB session bean is carried out using an EJB adapter.
