Invoking OpenEdge SOAP Web Service Operations from ABL

Invoking a Web service operation can be a simple process of returning a value and using it directly, or it can require a more complex treatment. The more complex treatment can include interacting with the SOAP message headers, handling SOAP faults, parsing and building complex parameters, or simply managing the serialized XML of a simple parameter.

This chapter describes how to invoke and manage the data associated with an operation for all of these requirements.
