The Client Definition File (CDF) contains all of the information needed by the SOAPAMCP process to map an IPM to a Web service request and map the Web service response back to an IPM. You use the WSDL2CDF utility to generate a CDF file from the Web Services Description Language (WSDL) file that describes the Web service you want to access.

It is common for Web services to use arbitrary-length strings and unbounded arrays in their type definitions. Since your application will use interprocess messages (which have a finite size) to access Web services, you must set specific limits on the sizes of these items. This may require some minor editing of the CDF that was generated by WSDL2CDF.

This section explains the Client Definition File creation and editing process.
