Problem is fetching XML body from Soap part

[raul8]

Hello,

I want to fetch the rest of the XML stored inside SOAP body, but with the below simple code, I'm not able to:

public class AttributeScanner {
	
	
	protected String getEnvOject(InputStream iStream)
			throws Exception {
		String xml = null;
		// First create the connection
		SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
		SOAPConnection connection = soapConnFactory.createConnection();

		// Next, create the actual message
		MessageFactory messageFactory = MessageFactory.newInstance();

		SOAPMessage message = messageFactory.createMessage();

		// Create objects for the message parts
		SOAPPart soapPart = message.getSOAPPart();
		SOAPEnvelope envelope = soapPart.getEnvelope();
		SOAPBody body = envelope.getBody();
		StreamSource preppedMsgSrc = new StreamSource(iStream);
		soapPart.setContent(preppedMsgSrc);		
		
		message.saveChanges();
		connection.close();		
		return xml;
	}
	
	public static void main(String[] args)throws Exception {
		InputStream iStream = new FileInputStream(new File(
				"./OrderAccepted.xml"));
				
		AttributeScanner scanner = new AttributeScanner();

		scanner.getEnvOject(iStream);

	}
}

Exception:
