16 - WSDL 1.1 PortType Element

The portType element describes a set of abstract operations and the abstract message that is involved in the operation.

The name attribute of the portType element is used for defining a unique name among all the port types that can be defined within the WSDL 1.1 document.

WSDL 1.1 Operation element

The operation element is used for describing a specific operation.

The name attribute of the operation element is used for defining a name for an operation.

The following is an example of the operation element in a WSDL 1.1 file. 

 

<wsdl:portType name = "WSDemoPortType">
    <wsdl:operation name = "helloWorld">
        <wsdl:input message = "ns:helloWorldRequest" wsaw:Action = "urn:helloWorld"/>
        <wsdl:output message = "ns:helloWorldResponse" wsaw:Action = "urn:helloWorldResponse"/>
    </wsdl:operation>
</wsdl:portType>

WSDL 1.1 has four primitive types of operations:

  • One-way: the endpoint receives a message. So the operation only has a single input element.
<wsdl:portType name = "WSDemoPortType">
    <wsdl:operation name = "helloWorld">
        <wsdl:input message = "ns:helloWorldRequest" wsaw:Action = "urn:HelloWorld"/>
    </wsdl:operation>
</wsdl:portType>
  • Request-response: the endpoint receives a message, and sends a correlated message. So the operation has one input element followed by one output element.
<wsdl:portType name = "WSDemoPortType">
    <wsdl:operation name = "helloWorld">
        <wsdl:input message = "ns:helloWorldRequest" wsaw:Action = "urn:helloWorld"/>
        <wsdl:output message = "ns:helloWorldResponse" wsaw:Action = "urn:helloWorldResponse"/>
    </wsdl:operation>
</wsdl:portType>
  • Solicit-response: the endpoint sends a message, and receives a correlated message. So the operation has one output element followed by one input element.
<wsdl:portType name = "WSDemoPortType">
    <wsdl:operation name = "helloWorld">
        <wsdl:output message = "ns:helloWorldResponse" wsaw:Action = "urn:helloWorldResponse"/>
        <wsdl:input message = "ns:helloWorldRequest" wsaw:Action = "urn:helloWorld"/>
    </wsdl:operation>
</wsdl:portType>
  • Notification: the endpoint sends a message. So the operation only has a single output element.
<wsdl:portType name = "WSDemoPortType">
    <wsdl:operation name = "helloWorld">
        <wsdl:output message = "ns:helloWorldResponse" wsaw:Action = "urn:helloWorldResponse"/>
    </wsdl:operation>
</wsdl:portType>
