Declaring xsi and xsd namespaces in both SOAP Envelope and Body content

[Vito Meuli]

Hi list!
I'm really desperate after some days spent on a problem.
Maybe someone can advise a way to the solution.

I'm writing a SOAP web service, and the response I should send is required to have the following namespaces declared twice:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

Once in the SOAP Envelope:

<soap:Envelope
  xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

and once in the root element inside the body:

  <soap:Body>
      <OTA_HotelResNotifRS
        xmlns="http://www.opentravel.org/OTA/2003/05"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <Errors>
            <Error Type="1">Found 1 valid reservations with CRS Confirmation Number=52690IC0000172, there should be none.</Error>
         </Errors>
      </OTA_HotelResNotifRS>
   </soap:Body>

I think it's redundant, but the server I'm sending responses to claims to need both.

My attempts to configure the JiBX mapping or to intercept the outgoing response and increment it have all failed.
Any suggestion please?

I'm using Spring WS and JiBX OXM, and I don't understand if the way to go is better configuring JiBX marshaller or better understand and apply the Axiom APIs in the interceptor.

I'll post the same question on the JiBX Users ML.

Cheers,
