Required tasks in the Web Service stage in DataStage®

The following diagram illustrates the minimum tasks that are required to set up a Web Service stage.

Required steps to set up a Web Service stage

Selecting a web service operation in DataStage

A Web Service stage calls a single operation. To select the operation, you use the Web Service stage, which you access through the Stage tab properties section.

For more information about selecting a web service operation, see Setting up Stage Properties.

Configuring a Web Service response in DataStage

A web service returns a SOAP message that the Web Service stage can decode into columns of one output row by using XPath expressions.

The returned SOAP message is decoded into five values.

To configure this option, you create output link properties with parameters and namespace data that comes from the WSDL definition of the web service operation.

As alternatives to decoding the response into a single row, you can:

  • Decode the SOAP message into multiple rows by using the Hierarchical Data stage as a linked stage.
  • Convert the content to another XML format by using the Hierarchical Data stage as a linked stage.
  • Use the SOAP message without modification in a linked stage.
  • Transformation data by using the appropriate stages.
