How to unmarshall SOAP response using JAXB if namespace declaration is on SOAP envelope?
You can use a StAX parser to parse the SOAP message and then advance the XMLStreamReader
to the getNumberResponse
element and use the unmarshal method that takes a class parameter. A StAX parser is included in Java SE 6, but you will need to download one for Java SE 5. Woodstox is a popular StAX parser.
Response
package forum11465653;public class Response { private long number; public long getNumber() { return number; } public void setNumber(long number) { this.number = number; }}
Demo
An XMLStreamReader
has a NamespaceContext
. The NamespaceContext
knows all the active namespace declarations for the current level. Your JAXB (JSR-222) implementation will be able to leverage this to get the necessary information.
package forum11465653;import java.io.FileReader;import javax.xml.bind.*;import javax.xml.stream.*;public class Demo { public static void main(String[] args) throws Exception{ XMLInputFactory xif = XMLInputFactory.newFactory(); XMLStreamReader xsr = xif.createXMLStreamReader(new FileReader("src/forum11465653/input.xml")); xsr.nextTag(); // Advance to Envelope tag xsr.nextTag(); // Advance to Body tag xsr.nextTag(); // Advance to getNumberResponse tag System.out.println(xsr.getNamespaceContext().getNamespaceURI("ns")); JAXBContext jc = JAXBContext.newInstance(Response.class); Unmarshaller unmarshaller = jc.createUnmarshaller(); JAXBElement<Response> je = unmarshaller.unmarshal(xsr, Response.class); System.out.println(je.getName()); System.out.println(je.getValue()); }}

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.
