SOAP WS (JAX-WS) with Java implementation : I receive null parameters because of the namespace qualified

Question

I got a SOAP project with JAX-WS and in my WSDL file the attribute elementFormDefault is set to qualified. Because of this, the xml request generated has the namespace (proj:) in front of all the elements :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:proj="http://my-project.com/Project">
   <soapenv:Header/>
   <soapenv:Body>
      <proj:Consultation>
         <proj:Header>
            <proj:WSVersion>value</proj:WSVersion>
            <proj:TimeRequete>value</proj:TimeRequete>
            <proj:IDRequest>value</proj:IDRequest>
         </proj:Header>
         <proj:Element1>value</proj:Element1>
         <proj:Element2>value</proj:Element2>
         <proj:limit>value</proj:limit>
      </proj:Consultation>
   </soapenv:Body>
</soapenv:Envelope>

The problem is that on the server side, all the elements I retrieve are null. But when I remove the namespace tag from the elements (like when the attribute elementFormDefault is set to unqualified) I can access all my elements and it works perfectly. Like this :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:proj="http://my-project.com/Project">
   <soapenv:Header/>
   <soapenv:Body>
      <proj:Consultation>
         <Header>
            <WSVersion>value</proj:WSVersion>
            <TimeRequete>value</proj:TimeRequete>
            <IDRequest>value</proj:IDRequest>
         </Header>
         <Element1>value</proj:Element1>
         <Element2>value</proj:Element2>
         <limit>value</proj:limit>
      </proj:Consultation>
   </soapenv:Body>
</soapenv:Envelope>

Unfortunately, I cannot change the elementFormDefault to unqualified : I can't modify the WSDL file... and all the request generated got the namespace tag "proj:" before the element in the xml request.

I searched and I'm kinda sure that this is a namespace problem with some annotations like in the @WebResult, @WebMethod etc. on the server side but I've tried modifying all this, setting the namespaces, deleting them... It doesn't seem to work.

Here is my WSDL File :

The Java implementation :

package web.service.server.myproject;


@WebService(name = "myProject", targetNamespace = "http://my-project.com/Project")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public class MyProjectServiceImpl implements MyProjectService {

    @Override
    @WebMethod(operationName = "Consultation", action = "http://my-project.com/Project/Consultation")
    @WebResult(name = "ConsultationResponse", targetNamespace = "http://my-project.com/Project", partName = "response")
    public ConsultationResponse consultation(Consultation request)
        throws MyProjectDefaultMessage {

            // some code...

        }

    @Override
    @WebMethod(operationName = "Update", action = "http://my-project.com/Project/Update")
    @WebResult(name = "UpdateResponse", targetNamespace = "http://my-project.com/Project", partName = "response")
    public UpdateResponse update(Update request)
        throws MyProjectDefaultMessage {

            // some code ...

        }
}

And some elements :

package web.service.server.myproject.types;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "header",
    "element1",
    "element2",
    "limit"
})
@XmlRootElement(name = "Consultation")
public class Consultation {

    @XmlElement(name = "Header", required = true)
    protected HeaderRequeteType header;
    @XmlElement(name = "Element1")
    protected String element1;
    @XmlElement(name = "Element2")
    protected String element2;
    protected Integer limit;

    // getters and setters

}

and

package web.service.server.myproject.types;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "EnteteRequeteType", propOrder = {
    "VersionWS",
    "timeRequete",
    "idRequest",
})

public class HeaderRequeteType {

    @XmlElement(name = "WVersionS", required = true)
    protected String versionWS;
    @XmlElement(name = "TimeRequete", required = true)
    @XmlSchemaType(name = "dateTime")
    protected XMLGregorianCalendar timeRequete;
    @XmlElement(name = "IDRequest", required = true)
    protected String idRequest;

    // getters and setters

}

I also tried adding in the @XmlType the namespace but it didn't seem to work

Note :

• I've change the names etc. from the WSDL and the java code so it would be easier to analyse. I also reduced them a lot. If there is some little mistyping mistakes, this is not the problem.
• On the server side, it seems that it recognizes the request as a 'Consultation' or an 'Update' object, but everything inside is null (Header, Element1, Element2 ...)
• If you need more infos, feel free to ask

If someone can help me I would be very grateful, this problem is actually driving me insane. Thanks !

Answer 1

I finally managed to resolve the problem.

I added a

package-info.java

class in my package with all the types of my web service.

@javax.xml.bind.annotation.XmlSchema(namespace = "http://my-project.com/Project", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package web.service.server.myproject.types;

If I understand correctly, this put a package level annotation so my elements are all linked to my namespace.

I hope this will help next people with the same problem :)
