Create a Web Services Consumer for the Stock Quote Service

You can create a Web services consumer for the Stock Quote service in Sterling B2B Integrator.

1. Check-in the WSDL.

   For more information, see Check In a WSDL for a Web Service.

2. Create a business process named StockQuoteConsumer.bp:
   1. Create an entry in the GPM pallet corresponding to the checked-in WSDL, which can be used while writing the business process.
   2. Use the following “assign” statements and “DomToDoc” service to create a primary document for the execution of the business process:

      <assign to="stockin:symbol">GISSC</assign>
      <assign to="stockin:GetQuote" 
      from="//*[namespace-uri()='http://www.webservice.stockquotein'
      and local-name()='symbol']"/>
      <assign to="Root"
      from="//*[namespace-uri()='http://www.webservice.stockquotein' and
      local-name()='GetQuote']"/>
      <assign name="Assign" to="." 
      from="DOMToDoc(/ProcessData/Root,&apos;PrimaryDocument&apos;)">
      </assign>

   3. Add the following lines in the namespaces.properties file:

      stockout=http://www.webservice.stockquoteout

      stockin=http://www.webservice.stockquotein

      The complete business process (including the input document) is as follows:

      
      <process name="StockQuoteConsumerBP">
          <sequence>
              <assign to="stockin:symbol">GRGSC</assign>

              <assign to="Root" from="//*[namespace-uri()='http://www.webservice.stockquotein' and local-name()='GetQuote']"/>
              <assign name="Assign" to="." from="DOMToDoc(/ProcessData/Root,&apos;PrimaryDocument&apos;)"></assign>

3. Execute the business process.
   This will be the response in the primary document:
