How to unmarshall SOAP response using JAXB if namespace declaration is on SOAP envelope?

Question

JAXB can only unmarshall an XML if the soap envelope has already been removed. However, the SOAP response I\'m trying to unmarshall has its namespace declaration on the soap

Answer 1

You could parse the whole SOAP message using a DOM parser, which would be able to resolve all the namespaces at parse time. Then extract the element you require from the resulting DOM tree and pass that to the unmarshaller.

DomDemo

package forum11465653;

import java.io.File;
import javax.xml.bind.*;
import javax.xml.parsers.*;
import javax.xml.transform.dom.DOMSource;
import org.w3c.dom.*;

public class DomDemo {

    public static void main(String[] args) throws Exception{
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setNamespaceAware(true);
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document d = db.parse(new File("src/forum11465653/input.xml"));
        Node getNumberResponseElt = d.getElementsByTagNameNS("http://example.com/", "getNumberResponse").item(0);

        JAXBContext jc = JAXBContext.newInstance(Response.class);
        Unmarshaller unmarshaller = jc.createUnmarshaller();
        JAXBElement je = unmarshaller.unmarshal(new DOMSource(getNumberResponseElt), Response.class);
        System.out.println(je.getName());
        System.out.println(je.getValue());
    }

}

Output

{http://example.com/}getNumberResponse
