How to get SOAPAction from the WSDL using Java

I am using javax.wsdl package for parsing the wsdl file.

I am not sure how to get the SOAPAction of an operation from the wsdl file.

I am able to get the javax.wsdl.Operation object using the WSDLFactory. But I find no way to get the SOAPAction of that operation.

Anybody has idea on how to get it?

Thanks, Maviswa

You need to get the ExtensibilityElement that corresponds to the SOAPOperation and extract the SOAPAction from there.

Let's take a simple WSDL as example, from the TempConvert Web Service, and extract the SOAP action from its CelsiusToFahrenheit operation; I'm going after this part:

<wsdl:binding name="TempConvertSoap" type="tns:TempConvertSoap">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="FahrenheitToCelsius">
      <soap:operation soapAction="http://tempuri.org/FahrenheitToCelsius" style="document"/>
      <wsdl:input>
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output>
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
    <wsdl:operation name="CelsiusToFahrenheit">
      <soap:operation soapAction="http://tempuri.org/CelsiusToFahrenheit" style="document"/>
      <wsdl:input>
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output>
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>

The following code prints the value of the SOAP action for the CelsiusToFahrenheit operation:

WSDLFactory factory = WSDLFactory.newInstance();
WSDLReader reader = factory.newWSDLReader();
Definition definition = reader.readWSDL("http://www.w3schools.com/webservices/tempconvert.asmx?wsdl");
Binding binding = definition.getBinding(new QName("http://tempuri.org/", "TempConvertSoap"));
BindingOperation operation = binding.getBindingOperation("CelsiusToFahrenheit", null, null); 
List extensions = operation.getExtensibilityElements();
if (extensions != null) {
    for (int i = 0; i < extensions.size(); i++) {
        ExtensibilityElement extElement = (ExtensibilityElement) extensions.get(i); 

        // ....

        if (extElement instanceof SOAPOperation) {
            SOAPOperation soapOp = (SOAPOperation) extElement;
            System.out.println(soapOp.getSoapActionURI());
        }

        // ....
    }
}

The output is this:

http://tempuri.org/CelsiusToFahrenheit
