Eventually i am getting some or other exception.
Can you please guide me with best suitable solution for the below xml
I have tried using Jaxb Marshaller

Below is the Java Code which i have tried

private Map<String, String> namespaceMap = new HashMap<>();



/**

 * Create mappings.

 */

public DefaultNamespacePrefixMapper() {

    namespaceMap.put("http://www.w3.org/2005/Atom", "");

    namespaceMap.put("http://schemas.microsoft.com/ado/2007/08/dataservices", "d");

    namespaceMap.put("http://schemas.microsoft.com/ado/2007/08/dataservices/metadata", "m");

    namespaceMap.put("http://www.georss.org/georss", "georss");

    namespaceMap.put("http://www.opengis.net/gml", "gml");

}



@Override

public String getPreferredPrefix(String namespaceUri, String suggestion, boolean requirePrefix) {

    return namespaceMap.getOrDefault(namespaceUri, suggestion);



}





DefaultNamespacePrefixMapper defaultNamespacePrefixMapper = new DefaultNamespacePrefixMapper();



    System.out.println("Response is::::"+response);

    JAXBContext jaxbContext =JAXBContext.newInstance(Entry.class);



    Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

    unmarshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", new DefaultNamespacePrefixMapper());

    Object sharePointResponse = unmarshaller.unmarshal(inputStream);
