Unmarshalling Error when I try to unmarshall the WebServiceResponse

Question

I have a response from a 3rd party API, that give me an error for unmarshalling the xml response is similar to that:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:webServiceResponse
    xmlns="http://ws.services.company.com"
    xmlns:ns2="http://rest.ws.services.company.com">
    <ns2:result>
        <success>true</success>
        <id>7054986</id>
    </ns2:result>
</ns2:webServiceResponse>

Normally I was testing my Java code with a xml response like that and I get success:

<webServiceResponse xmlns="http://ws.services.company.com">
  <result>
    <success>true</success>
    <id>1</id>
  </result>
</webServiceResponse>

In Java, I have been creating the respective XML Data class with the following xsd files.

Can anyone help regarding this issue?

I think it cant associate the response namespace with ns2 which is associated with the uri start as rest. But I cant to do it on xsd files to associate with ns2 as it gives error all time.

Answer 1

Your target namespace in XSD, and so in your Java generated code is targetNamespace="http://ws.services.company.com" but you receive the webServiceResponse in the http://rest.ws.services.company.com namespace.

That why the unmarshaller complains about not receiving one of the expected elements

Is your XSD created by yourself or send by someone else ? In any case to make it work, you should change the targetNamespace according to the expected one (with the rest prefix in it).
