Release 10.1A: OpenEdge Development:
Web Services

Defining object IDs in WSDL

This is a sample of the types section that might appear in the WSDL for many of the sample Web services in this chapter. (This example is for RPC/Encoded, but similar for all SOAP formats):

WSDL Containing an object ID definition

<types>    <schema elementFormDefault="unqualified"       targetNamespace="urn:OrderSvc:OrderInfo"       xmlns="http://www.w3.org/2001/XMLSchema">       <import namespace="http://schemas.xmlsoap.org/soap/encoding/"/>       <complexType name="OrderInfoID">          <sequence>             <element name="UUID" type="xsd:string"/>          </sequence>       </complexType>       <!-- Temp Table declarations here (if any) -->    </schema>    <!-- Additional Object Schema Declarations (if any) --> </types>

Note: The samples in this chapter are not all available on the Documentation and Samples CD or Progress Documentation Web site.

The WSDL schema definition for each Web service object (except a session-free AppObject) defines the SOAP header element that contains the value of its object ID as a <complexType>. As shown in the example, the name for the SOAP header element is the name of the <complexType>, in this example, "OrderInfoID". The name of the element that contains the value of the object ID is "UUID", defined as an element of type "xsd:string". This definition is the same for the object IDs of all Web service objects, differing only in the name of the object ID element.
