Release 10.1A: OpenEdge Development:
Web Services

Accessing a port type for a Web service

While the Web service is bound to a server object, you can create and map a procedure object to the port type supported by the binding in order to invoke its Web service operations using this syntax:

Syntax

RUN portTypeName [ SET hPortType ] ON SERVER hWebService .

As a result of executing a RUN statement using this syntax, you can access operations defined by the specified port type (portTypeName) in the Web service mapped to the server object handle, hWebService. You can invoke these operations by executing them as procedures or user-defined functions on the procedure object handle, hPortType, which is now mapped to the port type, portTypeName.

The RUN statement accomplishes this mapping by creating a procedure object for the port type and attaching it to the specified procedure object handle:

Accessing a port type for a Web service

DEFINE VARIABLE hWeatherSrv AS HANDLE. DEFINE VARIABLE hTempPT AS HANDLE. CREATE SERVER hWebService. hWeatherSrv:CONNECT("-WSDL http://.../WorldWeather.wsdl                      -Service WeatherService                      -Port TemperaturePort"). RUN TemperaturePortType SET hTempPT IN hWeatherSrv.

Note: The abbreviated URL for the Web service in this example is completely fictitious, and any resemblance to an actual public Web service is coincidental.

You can now invoke and manage all of the operations in the port type, TemperaturePortType, defined for the Web service, WeatherService. For more information on using procedure handles to invoke Web service operations, see Chapter 10, " Invoking Web Service Operations from the Progress 4GL."
