As discussed in my previous post, using Oracle BPM to consume services exposed through Oracle Service Bus is the most common type of integration.  In the diagram below you can see the highlighted path that is taken in this case.  All of the communication is between the BPM execution engine, Service Bus, and the back end web services.

Over the past few years we have seen many of our customers use a combination of Oracle BPM/Aqualogic BPM and Oracle Service Bus/Aqualogic Service Bus.  These two products are very complimentary within a company's SOA environment.  OSB can provide the service aggregation, transformation, and security while OBPM can provide the orchestration of the services that OSB exposes.  This blog post will describe the different use cases for integrating OBPM and OSB and in follow up posts each integration will be covered in more detail.
