Scenario: Reusing common application logic in multiple integration solutions

In IBM® WebSphere® Message Broker Version 8.0, you use subflows to group common functionality that you want to use several times within multiple integration solutions. You can create subflows as a .subflow file or as a .msgflow file, although creating a .subflow file is the recommended approach for new developments.

Subflows created as a .msgflow file are maintained for compatibility with earlier versions. You should convert these subflows into .subflow files.

This scenario explains how WebSphere Message Broker Version 8.0 handles subflows created as a .subflow file and as a .msgflow file; provides guidance on how to design a subflow depending on the type; and demonstrates how to convert legacy subflows into WebSphere Message Broker Version 8.0 subflows.

This scenario uses the Error Handler sample provided in WebSphere Message Broker Version 8.0 to explain how to version subflows and how to convert legacy subflows. You can use the Error Handler sample or you can use your own integration solutions.
