WOXMLDecoder NullPointerException

To: 
"WO Dev Group" 
Hi Group,

Following code to decode an xml file or xml string is resuting in NPE, could 
you any one please advise what's going wrong here:

WOXMLDecoder xmlDecoder = WOXMLDecoder.decoder();
//InputStream is = 
application().resourceManager().inputStreamForResourceNamed("supra.xml", null, 
null);
//supra.xml has similar xml as shown in xmlString below, but little elaborated.
//System.out.println("is..." + is);
//Object obj = xmlDecoder.decodeRootObject(new NSData(is, 1024));
String xmlString = "123";
StringReader stringReader = new StringReader(xmlString); 
InputSource is = new InputSource(stringReader); 
Object obj = xmlDecoder.decodeRootObject(is);
System.out.println("childe: " + xmlDecoder.valueForKey("childe"));
