SOAP Binding type does not have impact on the resulting WSDL

Question

I tried the sample code from mkyong site and played around with combination of parameters. I tried changing the javax.jws.soap.SOAPBinding.Use.LITERAL to javax.jws.soap.SOAPBinding.Use.ENCODED for an RPC style service interface.

    package com.mkyong.ws;

    import javax.jws.WebMethod;
    import javax.jws.WebService;
    import javax.jws.soap.SOAPBinding;
    import javax.jws.soap.SOAPBinding.Style;
    import javax.jws.soap.SOAPBinding.Use;
    import javax.jws.soap.SOAPBinding.ParameterStyle;

    //Service Endpoint Interface
    @WebService
    @SOAPBinding(style = Style.RPC, use = Use.ENCODED, parameterStyle = ParameterStyle.WRAPPED)
    public interface HelloWorld{

        @WebMethod String getHelloWorldAsString(String name);

    }

The only change was instead of use = Use.LITERAL now I have use = Use.ENCODED. However the resulting WSDL does not seem to change at all.

The WSDL created in both cases still shows the <soap:body> use property as "literal".

<soap:body use="literal"

Is there a mistake somewhere in my declaration of the interface?

<binding name="HelloWorldImplPortBinding" type="tns:HelloWorld">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"></soap:binding>
    <operation name="getHelloWorldAsString">
        <soap:operation soapAction=""></soap:operation>
        <input>
            <soap:body use="literal" namespace="http://ws.mkyong.com/"></soap:body>
        </input>
        <output>
            <soap:body use="literal" namespace="http://ws.mkyong.com/"></soap:body>
        </output>
    </operation>
</binding>

Is this correct? Should I not be expecting use="Encoded"?

Answer 1

In few of the WS implementation Use.ENCODED is not implemented. This may be one of the reason why use are getting the same WSDL. rpc/encoded wsdls are not supported in JAXWS 2.0. rpc/encoded is also not supported in JAXWS 2.2. Please refer the below link for the same. https://jax-ws.java.net/2.2.1/docs/annotations.html.
