Use the Workflow Manager to create a web service workflow. To create a web service workflow, enable the Web Service option for the workflow and then configure the web service properties.

When you create a session in a web service workflow, the session is called a web service session. You can include the following types of mappings in a web service session:

A web service session uses a Web Services Provider reader and writer. If a web service mapping contains a web service source and target, the session uses the Web Services Provider reader and writer by default. If a web service mapping contains a flat file or XML source or target, you must change the reader and writer type to the Web Services Provider reader or writer.

When a web service session contains XML or flat file sources or targets, the client application sends a request to the Web Services Hub as a MIME attachment to the SOAP message. To send or receive attachments, a client application must be created using a toolkit that supports MIME attachments.

When the Web Services Hub receives a SOAP message request to run a web service workflow, it passes the request to the Integration Service. After the Integration Service runs the web service request, it passes the response to the Web Services Hub. The Web Services Hub generates a SOAP message response and passes it back to the web service client.

You can set up multiple partitions in a session that contains web service source and target definitions. The Integration Service creates a connection to the Web Services Hub based on the number of sources, targets, and partitions in the session.
