Sample implementation script and WSDL document

The following document literal web service returns a stock quotation for a ticker symbol. This limited example returns only a value for the IBM® ticker; all other arguments result in a SOAP fault.

The implementation script is as follows:
// parse the request document
var doc = new XmlDocument(soapMessage);

// get the ticker parameter
var ticker = parseXMLNode("ibm:ticker");

// we only give out ibm quotes around here...
if (ticker == "IBM") {
out.println("<ibm:getStockQuoteResponse
xmlns:ibm=\"http://ibm.com/wpc/test/stockQuote\">");
out.println("<ibm:response>123.45</ibm:response>");
out.println("</ibm:getStockQuoteResponse)");
}
else {
soapFaultMsg.print("Only quotes for IBM are supported");
}

The result of running this script is that IBM Product Master does the following things:
  1. Receives a SOAP request from the Axis SOAP stack.
  2. Validates the request message against the previous schema.
  3. Starts the web service trigger script. The input variables are:
    - operationName = "getStockQuote"- message = "<getStockQuote>
<ticker>IBM</ticker>
</getStockQuote>"
    The trigger script writes the response to the out writer:
    - out = "<getStockQuoteResponse>
<response>83.76</response>
</getStockQuoteResponse>"
  4. Validates the response against the previous schema.
  5. Sends the entire SOAP response back to the client through the Axis SOAP stack.
