Question

My schema specifies a namespace, but the documents don’t. What’s the simplest way to ignore namespace during JAXB unmarshalling (XML -> object)?

In other words, I have

<foo><bar></bar></foo> 

instead of,

<foo xmlns='http://tempuri.org/'><bar></bar></foo>

I believe you must add the namespace to your xml document, with, for example, the use of a SAX filter.

That means:

• Define a ContentHandler interface with a new class which will intercept SAX events before JAXB can get them.
• Define a XMLReader which will set the content handler

then link the two together:

public static Object unmarshallWithFilter(Unmarshaller unmarshaller, java.io.File source) throws FileNotFoundException, JAXBException  {     FileReader fr = null;     try {         fr = new FileReader(source);         XMLReader reader = new NamespaceFilterXMLReader();         InputSource is = new InputSource(fr);         SAXSource ss = new SAXSource(reader, is);         return unmarshaller.unmarshal(ss);     } catch (SAXException e) {         //not technically a jaxb exception, but close enough         throw new JAXBException(e);     } catch (ParserConfigurationException e) {         //not technically a jaxb exception, but close enough         throw new JAXBException(e);     } finally {         FileUtil.close(fr); //replace with this some safe close method you have     } }
