Using SOAP to Access a Third-Party Web Service

You want a job to access a third-party web service that uses a SOAP interface.

Create a job that uses a SOAP transformation to access the web service. SOAP (Simple Object Access Protocol) is a simple XML-based protocol to let applications exchange information over HTTP. The SOAP transformation generates SAS SOAP procedure code to access a web service in the context of a job. The procedure invokes a SOAP web service through Java Native Interface (JNI). The procedure provides options for the request XML document (IN), the service endpoint (URL), the SOAP action or operation (SOAPACTION), and the map used to handle the response (OUT).

To use the SOAP transformation, perform the following tasks:

It is assumed that you are familiar with how to use the SOAP interface to access web services. Gather the same information that you need to use the SAS SOAP procedure to read from and write to the desired web service. Example options and values are shown in the next section. For detailed information about the SAS SOAP procedure, see the documentation for that procedure in the Base SAS Procedures Guide.

Perform the following steps. It is assumed that you are familiar with creating SAS Data Integration Studio jobs, as described in Creating Jobs.

The following table shows an example set of options that you can specify in the SOAP transformation. In this example, the web service is available from the National Weather Service in the United States. For the example transaction, a ZIP code is passed to the service in XML format (WeatherGovRequestXML.xml). The service returns the longitude and latitude for that ZIP code in XML format (SOAPSoapActionOutputFile.xml).
