About building a Web services client
A PowerBuilder application can act as a client consuming a
Web service that is accessed through the Internet. Using SOAP and
WSDL, a collection of functions published remotely as a single entity
can become part of your PowerBuilder application. A Web service
accepts and responds to requests sent by applications or other Web
services.
Invoking Web services through SOAP requires serialization
and deserialization of data types, and the building and parsing
of XML-based SOAP messages. Using objects from an extension file
or dynamic library that installs with PowerBuilder, the Web services
client proxy performs these tasks for you—thereby eliminating
the need to have extensive knowledge of the SOAP specification and
schema, the XML Schema specification, or the WSDL specification
and schema.
