Configuring a Web Service request in DataStage®

The Web Service stage sends requests, one row at a time to the web service, which are encoded in a SOAP message. If the data required for the request is stored in one row, configure a request that uses the Web Service stage and the appropriate data extraction stage. This task involves importing the operation metadata from the input message table definition as input link properties.

In the simplest case, a web service operation expects a single parameter value as input to an operation, and your input data contains multiple rows with a single value. Each row is processed in a separate request.

For example, you send a city name in a request, and the web service operation returns current temperature. The following diagram illustrates three input rows that supply city values for different requests against the same web service operation.
