Chapter 8. Integration using WebSphere Business Integration Adapters 205
In conjunction with the Business Object Designer, the ODA can allow batch
business object creation and special filtering, providing for an easier
development path to integrate to the underlying EIS.
8.3 Adapter-based integration building block
The WebSphere Business Integration Adapter integration building block involves
the adapter exposed as a service in the Business Process Container of
WebSphere Business Integration Server Foundation. Then a request processing
call is exposed as a service to the Stock Analysis business process.
8.3.1 Scenario problem statement
The buy shares scenario requires stock information, which is stored in an
external EIS. The EIS has the information that is required. The WebSphere
Business Integration Adapter for JDBC provides for the retrieval of this
information from the database of the EIS.
8.3.2 System architecture
The WebSphere Business Integration Adapter for JDBC resides on the machine
where the database repository is located. The system analysis business
processes makes a request for stock information through the system process.
The context information that is passed within the request allows the system
process to route the message to the appropriate provider. The stock analysis
business process and the system process are both running in WebSphere
Business Integration Server Foundation on a separate machine and making calls
on the adapter through its exposed service process.
See Chapter 3, “Scenario overview and design” on page 65 for the system
design view.
8.3.3 Components of the building block
The components of the adapter integration building block include:
???? WebSphere Business Integration Adapter Framework
???? The BPEL process, which wraps the adapter service
???? The adapter service, which exposes the adapters stock retrieval operation
???? The business object, which is used to represent the stock data
???? The critical business process, which uses this service.
