When you configure a web service session, you can configure the session reader and writer. By default, a web service session with web service sources and targets uses a Web Services Provider reader and writer.

If a web service session contains a flat file or XML source or target, you must configure the session to use the Web Services Provider reader or writer. The Web Services Hub sends requests and responses as MIME attachments to the SOAP message.

When you configure the reader for a web service session, you configure terminating conditions, such as idle time and message count.

When you configure the writer for a web service session, you configure caching information that the Integration Service uses to cache target data. You can also configure the output format for the target data.

Use the Workflow Manager to configure a web service session. In the Workflow Designer, edit the session of a web service workflow. To configure the Web Services Provider reader, click the Mapping tab and select a source. To configure the Web Services Provider writer, select a target.
