Release 10.1A: OpenEdge Development:
Web Services

Accessing multiple port types simultaneously

If you want to maintain access to two or more port types at the same time (for the same or a different Web service), you must create and bind the Web service to a separate server object handle for each port type that you want to access. Then create and map a separate procedure object handle to each port type.

This example binds two Web services (WeatherService and SailingService) in order to access three port types (TemperaturePortType, WindPortType, and RentalPortType) at the same time:

Accessing multiple port types simultaneously

DEFINE VARIABLE hWebServiceTempPT AS HANDLE. DEFINE VARIABLE hWebServiceWindPT AS HANDLE. DEFINE VARIABLE hWebServiceSchedulePT AS HANDLE. CREATE SERVER hWebServiceTempPT. CREATE SERVER hWebServiceWindPT. CREATE SERVER hWebServiceSchedulePT. hWebServiceTempPT:CONNECT( "-WSDL http://.../WorldWeather.wsdl"                             -Service WeatherService                             -Port TemperaturePort"). hWebServiceWindPT:CONNECT( "-WSDL http://.../WorldWeather.wsdl"                             -Service WeatherService                             -Port WindPort"). hWebServiceSchedulePT:CONNECT( "-WSDL http://.../SailingSchedule.wsdl"                             -Service SailingService                             -Port RentalPort"). DEFINE VARIABLE hTempPT AS HANDLE. DEFINE VARIABLE hWindPT AS HANDLE. DEFINE VARIABLE hRentalPT AS HANDLE. RUN TemperaturePortType SET hTempPT IN hWebServiceTempPT RUN WindPortType SET hWindPT IN hWebServiceWindPT RUN RentalPortType SET hRentalPT IN hWebServiceSchedulePT . . .

Note: The abbreviated URLs for the Web services in this example are completely fictitious, and any resemblance to actual public Web services is coincidental.
