Requirements for Web Service Jobs

A Web service job is a SAS Data Integration Studio job that is designed to be executed by a Web service client. The process flow for a Web service job has these requirements:
  • The job can receive zero or more inputs from the Web service client that executes the job.
  • The job can send zero or one output to the client that executes the job.
  • Input to the job from the client, and output from the job to the client, must be in XML table format.
  • The XML tables that specify client input or output in the job must be members of a SAS XML library. For details about SAS XML libraries, see the SAS XML LIBNAME Engine: User's Guide.
  • The XML table for a client input can have an XMLMap associated with it through the library. An XMLMap can help the XML LIBNAME engine to read the table. However, the XML table that specifies a client output cannot have an XMLMap associated with it through the library.
  • The XML table for each client input or output in the job must have a unique libref.
  • The XML table for each client input or output in the job must be configured as a Web stream.
The following display illustrates a typical process flow for a Web service job.
Sample Process Flow for a Web Service Job
Sample Process Flow for a Web Service Job
In the sample flow, INTABLE is a metadata object for an input table in XML format. Convert Temp GT is a generated transformation with custom SAS code that processes the input. OUTTABLE is a metadata object for an output table in XML format. The small blue circle that overlays the table icons indicates that the input table and output table are configured as Web streams.
The preceding Web service job is deployed as a stored process. Then the stored process is deployed as a Web service. Users with Web client software access the Web service job, and they are prompted to supply input. The job processes the input and displays the result to the Web client.
