This topic
provides background information about the SOAP messages that are
sent in Web Service Example 5: Document-Oriented Method with
Complex Type Parameters.
In example 5, the following
client SQL statement is executed:
INVOKE
TRAVELCOMPONENT.GETSCHEDULEDTOURS
WITH
SELECT '<Destination
xmlns="http://MyWebServer/TravelService/TRAVELSERVICE.wsdl">AUSTRALIA</Destination>'
The Web Service component
handles this statement, and composes a SOAP request message. The
information how to compose this message is defined in the
TRAVELSERVICE.wsdl file:
<wsdl:operation
name="GetScheduledTours">
<soap:operation
soapAction="http://MyWebServer/TravelService/TRAVELSERVICE.asp#GetScheduledTours"
style="document"/>
<wsdl:input
name="GetScheduledTours">
<soap:body
use="literal"/>
</wsdl:input>
<wsdl:output
name="GetScheduledToursResponse">
<soap:body
use="literal"/>
</wsdl:output>
</wsdl:operation>
In this code fragment, the
attributes style="document" and use="literal" do NOT result in any
method names or parameter names appearing in the SOAP request
message. This is why in a document-oriented method, all XML
elements must be included in the SQL statement:
<?xml version="1.0"
encoding="UTF-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<Destination
xmlns="http://MyWebServer/TravelService/TRAVELSERVICE.wsdl"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
AUSTRALIA
</Destination>
</soapenv:Body></soapenv:Envelope>
The body of this SOAP request
message includes the XML elements that are included in the SQL
statement.
Next, the following statement
is sent to the Rules Service:
INVOKE
TRAVELSERVICE.GetScheduledTours
WITH
SELECT '... soap message above ...'
request
Then, the Web Service provider
composes a SOAP response:
<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:tns="http://MyWebServer/TravelService/TRAVELSERVICE.wsdl">
<soap:Body>
<tns:Scheduled_Tours
documentName="Scheduled Tours">
<SCHEDTOUR
TOUR_TYPE="ISLAND SUNTANNER" START_DATE="2005-11-01000000"
RETURN_DATE="2005-11-13000000" PRICE="120" MAX_PART="10"
GUIDE="137">
</SCHEDTOUR>
<SCHEDTOUR
TOUR_TYPE="ISLAND SUNTANNER" START_DATE="2005-11-15000000"
RETURN_DATE="2005-11-27000000" PRICE="122" MAX_PART="5"
GUIDE="6">
</SCHEDTOUR>
</tns:Scheduled_Tours>
</soap:Body>
</soap:Envelope>
The body of this SOAP response
message only includes the Scheduled_Tours parameter of the web
service provider method in XML format.
