B2B Data Exchange uses JMS to send and receive documents to and from PowerCenter real-time workflows. The documents you send to JMS can be text or binary.

When using a real-time workflow, you must add a JMS source definition to a mapping designed to receive and process Data Exchange documents. If you send documents to B2B Data Exchange after processing, you must also define a JMS target. You create the JMS source and target definitions for Data Exchange mappings in the PowerCenter Designer in the same way you create JMS source and target definitions for other mappings. PowerCenter batch workflows can have a flat file source, or no source at all. For more information, see the

PowerCenter Designer Guide

.

The JMS source and target definitions require additional properties configured to work with B2B Data Exchange. These properties allow B2B Data Exchange to pass parameters from B2B Data Exchange to PowerCenter and from PowerCenter to B2B Data Exchange.

Batch workflows require additional mapping parameters to interact with B2B Data Exchange. These mapping parameters allow B2B Data Exchange to exchange information with PowerCenter. Batch workflows are invoked using the Web Services Hub.
