Create a Stock Quote Web Service

You can create a Stock Quote Web service in Sterling B2B Integrator.

To create a Stock Quote Web service:

Create an input schema that takes a stock symbol as input by placing the following schema in a file named stockQuoteInput.xsd:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema elementFormDefault="qualified" targetNamespace=
 "http://www.webservice.stockquotein"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="GetQuote">
    <xs:complexType>
      <xs:sequence>
        <xs:element minOccurs="0" maxOccurs="1" name="symbol" type="xs:string" />
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

For this input schema, Sterling B2B Integrator expects a SOAP Request similar to the following:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.ditasoap.org/soap/envelope/">
  <soap:Body>
    <GetQuote xmlns=" http://www.webservice.stockquotein">
      <symbol>string</symbol>
    </GetQuote>
  </soap:Body>
</soap:Envelope>

Create an output schema that gives the output as price by placing the following schema in a file named stockQuoteOutput.xsd:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema elementFormDefault="qualified" 
targetNamespace="http://www.webservice.stockquoteout"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="GetQuoteResponse">
    <xs:complexType>
      <xs:sequence>
        <xs:element minOccurs="0" maxOccurs="1" name="GetQuoteResult" type=
         "xs:string" />
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

The SOAP response sent from Sterling B2B Integrator using this output schema looks like the following:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.ditasoap.org/soap/envelope/"> 
  <soap:Body>
    <GetQuoteResponse xmlns="http://www.webservice.stockquoteout"> 
    <GetQuoteResult>string</GetQuoteResult> 
    </GetQuoteResponse>
  </soap:Body>
</soap:Envelope>

From the Administration menu, select Deployment >Schemas and check in these schemas.
Do not modify the target Namespace.
Add the following to namespaces.properties file to create the namespaces for use in the input and output schemas.
```
stockout=http://www.webservice.stockquoteout
stockin=http://www.webservice.stockquotein
```

Create a simple business process such as the following in Sterling B2B Integrator to handle the stock quote service functionality. It must return a price as the response by creating the output XML and assigning it to WebservicesResponseNode.

<process name="StockQuoteBP">
  <sequence name="AssignSequence"> 
	 <assign to="stockout:GetQuoteResult">120.35</assign>
	 <assign to="stockout:GetQuoteResponse" 
   from="//*[namespace-uri()='http://www.webservice.stockquoteout'
   and local-name()='GetQuoteResult']"/>
	 <assign to="WebservicesResponseNode" 
   from="//*[namespace-uri()='http://www.webservice.stockquoteout'
   and local-name()='GetQuoteResponse']"/>
  </sequence>
</process>

Check in the business process into Sterling B2B Integrator as StockQuoteBP.

From the Administration menu, select Deployment > Web Services > Schema Mappings, create a new business process schema mapping.
1. Select StockQuoteBP from the Business Process drop-down list.
2. Select stockQuoteInput.xsd from the Input Schema drop-down list.
3. Select stockQuoteOutput.xsd from the Output Schema drop-down list.
4. Select the check box next to Validate with Input Schema and Validate with Output Schema.
Create a Web service, StockQuoteWebservice, in Sterling B2B Integrator that includes this business process.
- Clear the Use Legacy Settings check box.
- Assign StockQuoteBP as the business process.
- Use default settings in all other pages.

Generate the WSDL for the Web service as shown in the following example:

Check in the WSDL and enable it for business processes.
Export the WSDL to a location accessible to the consumer, or send an XML file.
