Can not initialize the default wsdl from classpath:wsdl

I'm following an example to understand how SOAP works. I have generated code from wsdl using Apache cxf and I can log SOAP web service request e response. Apparently all works fine. I have just a problem to set a relative path. I've followed this solution How to avoid the need to specify the WSDL location in a CXF or JAX-WS generated webservice client?, but there isn't way to solve the log error on console.

The error message on console:

jun 03, 2021 2:17:38 PM io.codejournal.maven.wsdl2java.NumberConversion <clinit>
INFO: Can not initialize the default wsdl from classpath:wsdl/dataaccess-numberconversion.wsdl

this is my pom.xml:

My service class:

@WebServiceClient(name = "NumberConversion",
                  wsdlLocation = "classpath:wsdl/dataaccess-numberconversion.wsdl",
                  targetNamespace = "http://www.dataaccess.com/webservicesserver/")
public class NumberConversion extends Service {

    public final static URL WSDL_LOCATION;

    public final static QName SERVICE = new QName("http://www.dataaccess.com/webservicesserver/", "NumberConversion");
    public final static QName NumberConversionSoap = new QName("http://www.dataaccess.com/webservicesserver/", "NumberConversionSoap");
    public final static QName NumberConversionSoap12 = new QName("http://www.dataaccess.com/webservicesserver/", "NumberConversionSoap12");
    static {
        URL url = NumberConversion.class.getClassLoader().getResource("wsdl/dataaccess-numberconversion.wsdl");
        if (url == null) {
            java.util.logging.Logger.getLogger(NumberConversion.class.getName())
                .log(java.util.logging.Level.INFO,
                     "Can not initialize the default wsdl from {0}", "classpath:wsdl/dataaccess-numberconversion.wsdl");
        }
        WSDL_LOCATION = url;
    }

    public NumberConversion(URL wsdlLocation) {
        super(wsdlLocation, SERVICE);
    }

    public NumberConversion(URL wsdlLocation, QName serviceName) {
        super(wsdlLocation, serviceName);
    }

        super(WSDL_LOCATION, SERVICE);

    public NumberConversion(WebServiceFeature ... features) {
        super(WSDL_LOCATION, SERVICE, features);
    }

    public NumberConversion(URL wsdlLocation, WebServiceFeature ... features) {
        super(wsdlLocation, SERVICE, features);
    }

    public NumberConversion(URL wsdlLocation, QName serviceName, WebServiceFeature ... features) {
        super(wsdlLocation, serviceName, features);
    }
   
    /**
     *
     * @return
     *     returns NumberConversionSoapType
     */
    @WebEndpoint(name = "NumberConversionSoap")

    }

     * @return
     *     returns NumberConversionSoapType
     */
    @WebEndpoint(name = "NumberConversionSoap")
    public NumberConversionSoapType getNumberConversionSoap(WebServiceFeature... features) {
        return super.getPort(NumberConversionSoap, NumberConversionSoapType.class, features);
    }


    /**

     */
    @WebEndpoint(name = "NumberConversionSoap12")
    public NumberConversionSoapType getNumberConversionSoap12() {
        return super.getPort(NumberConversionSoap12, NumberConversionSoapType.class);
    }

    /**
     *
     * @param features
     *     A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.

    public NumberConversionSoapType getNumberConversionSoap12(WebServiceFeature... features) {
        return super.getPort(NumberConversionSoap12, NumberConversionSoapType.class, features);
    }

}

When I run this code URL url = NumberConversion.class.getClassLoader().getResource("wsdl/dataaccess-numberconversion.wsdl"); , I'll get a null value back. It is the wrong path that NumberConversion.class.getClassLoader() calls, because this class is in another package.

Any idea how to set in the right way?

Solution

  • There is a mismatch in your <wsdlOption>, between the <wsdl> and <wsdlLocation> values.

    <wsdl>${basedir}/src/main/resources/dataaccess-numberconversion.wsdl</wsdl>
<wsdlLocation>classpath:wsdl/dataaccess-numberconversion.wsdl</wsdlLocation>

    The first line says the file is in the root of the classpath but in your second line you say it's on a subpath called wsdl. Both cannot be true.

    So change your code to either:

    <wsdl>${basedir}/src/main/resources/wsdl/dataaccess-numberconversion.wsdl</wsdl>
<wsdlLocation>classpath:wsdl/dataaccess-numberconversion.wsdl</wsdlLocation>

    or to:

    <wsdl>${basedir}/src/main/resources/dataaccess-numberconversion.wsdl</wsdl>
<wsdlLocation>classpath:dataaccess-numberconversion.wsdl</wsdlLocation>

    What's after /src/main/resources/ and classpath: must match.

    Whatever variant you choose make sure that:
