JAX-WS: How to add additional XML namespaces to a SOAP response

I have a webservice autogenerated with JAXWS. This webservice is a simulator for the actual implementation and is used for testing. A response from the actual implementation looks like this:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
        xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        xmlns:nsc:RFIDCommandEnum="http://tempuri.org/nsc:RFIDCommandEnum.xsd"
        xmlns:nsc="http://xxx.com/schema/yyy/ltu-tcs"
        xmlns:nse:DeviceStateEnum="http://tempuri.org/nse:DeviceStateEnum.xsd"
        xmlns:nse="http://xxx.com/schema/yyy"
        xmlns:nsl="http://xxx.com/wsdl/yyy/ltu/tcs"
        xmlns:nst="http://xxx.com/wsdl/yyy/tcs/ltu">
    <SOAP-ENV:Header/>
    <SOAP-ENV:Body>
        <nsl:setDataResponse>
            <result>...</result>
        </nsl:setDataResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The same response by the simulator looks like this:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <ns2:getDataResponse xmlns:ns2="http://xxx.com/wsdl/yyy/ltu/tcs">
            <result>...</result>
       </ns2:getDataResponse>
    </S:Body>
</S:Envelope>

Now I already know that nested namespaces like xmlns:nsc:RFIDCommandEnum will cause problems, so I need to get the simulator deliver these namespaces like the actual implementation does. After some googling, I figured out I should do something like this:

@javax.xml.bind.annotation.XmlSchema(
    namespace = "http://xxx.com/schema/yyy/ltu-tcs",
    xmlns = {
        @javax.xml.bind.annotation.XmlNs(prefix = "nsc:RFIDCommandEnum", namespaceURI = "http://tempuri.org/nsc:RFIDCommandEnum.xsd"),
        @javax.xml.bind.annotation.XmlNs(prefix = "nsc", namespaceURI =  "http://xxx.com/schema/epm/ltu-tcs"),
        @javax.xml.bind.annotation.XmlNs(prefix = "nse:DeviceStateEnum", namespaceURI = "http://tempuri.org/nse:DeviceStateEnum.xsd"),
        @javax.xml.bind.annotation.XmlNs(prefix = "nse", namespaceURI = "http://xxx.com/schema/yyy"),
        @javax.xml.bind.annotation.XmlNs(prefix = "nsl", namespaceURI = "http://xxx.com/wsdl/yyy/ltu/tcs"),
        @javax.xml.bind.annotation.XmlNs(prefix = "nst", namespaceURI = "http://xxx.com/wsdl/yyy/tcs/ltu")
    },
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.xxx.yyy.tcs.simulator;

But it doesn't work. The package com.xxx.yyy.tcs.simulator is where the simulating implementation class of the webservice is located. I figured I probably need to apply these annotations to the autogenerated classes that represent the XML content, but cannot change these, because they are also used in production code and I don't want to pollute that with my namespaces.

So I tried to derive from my StandardResponse class which represents the <result> element:

package com.xxx.yyy.tcs.simulator;

// ...

@WebService(name = "LTU_for_TCS", targetNamespace = "http://xxx.com/wsdl/yyy/ltu/tcs")
public class LTU_for_TCS_Impl implements LTUForTCS {
    // ...

    public static final class NamespacePollutedStandardResponse extends StandardResponse {
        private NamespacePollutedStandardResponse(final Application application,
                                                  final ResultCodeEnum code,
                                                  final String message) {
            super(application, code, message);
        }
    }

    @WebMethod
    @WebResult(name = "result", partName = "result")
    @Override
    public GetLTUDataResponse getData(
            @WebParam(name = "application", partName = "application")
            Application application) {
        logger.info("getData");
        return new NamespacePollutedStandardResponse(getApplicationHeader(),
            ResultCodeEnum.SUCCESS,
            "This is the LTU simulator!");
    }
}

However, this still doesn't change the response I get from the simulator. Now I'm wondering: Can I change the namespace list of StandardResponse at all? Why doesn't it work like this - NamespacePollutedStandardResponse is part of the simulator package, so it should get the namespaces defined in the XmlSchema attribute, shouldn't it? And is there a way to add the namespaces to the root element instead (I only found information how to add it to one of the payload elements)?

You can add namespace to the root element

@XmlRootElement(namespace ="http://mynamespace.com")

I solved the problem by writing a javax.servlet.Filter that adds the additional namespaces to the response. This is not very pretty, but it's a lot easier to create an answer as close as possible to the original this way.
