Reading an ebXML message from a JAXMServlet

Question

I have the following servlet in Tomcat 4.1.18, using the contents of java_xml_pack-summer02_01:
public class Consume extends JAXMServlet implements OnewayListener
private ProviderConnectionFactory pcf;
private ProviderConnection pc;
private static final String providerURI = "http://java.sun.com/xml/jaxm/provider";
//private MessageFactory messageFactory;
public void init(ServletConfig servletConfig) throws ServletException
super.init(servletConfig);
try
pcf = ProviderConnectionFactory.newInstance();
pc = pcf.createConnection();
setMessageFactory(new EbXMLMessageFactoryImpl());
catch (Exception e)
e.printStackTrace();
throw new ServletException("Couldn't initialize " + this.getClass().getName() + " servlet: " + e.getMessage());
public void onMessage(SOAPMessage message)
EbXMLMessageImpl ebXML = null;
try
System.out.println("== messagetype=" + message.getClass().getName());
System.out.println("== constructing EbXMLMessage");
ebXML = (EbXMLMessageImpl)message;
System.out.println("== got EbXMLMessage " + ebXML.toString());
catch(Exception e)
System.out.println("== Couldn't create ebXML message from SOAP message: " + e);
if(ebXML!=null)
System.out.println("EbXML: From " + ebXML.getFrom().toString());
System.out.println("EbXML: To " + ebXML.getTo().toString());
System.out.println("EbXML: Sender " + ebXML.getSender().toString());
System.out.println("EbXML: Receiver " + ebXML.getReceiver().toString());
System.out.println("EbXML: CPAId " + ebXML.getCPAId());
System.out.println("EbXML: Conversation " + ebXML.getConversationId());
System.out.println("EbXML: Action " + ebXML.getAction());
System.out.println("EbXML: MessageId " + ebXML.getMessageId());
Manifest manifest = ebXML.getManifest();
Reference[] refs = manifest.getReferences();
for(int i=0; i<refs.length; i++)
System.out.println("EbXML ref " + refs.getId() + ": " + refs[i].getDescription());
...etc
However, after the "ebXML = (EbXMLMessageImpl)message;" line, all of the ebXML.get*() calls return null. If I use "ebXML = new EbXMLMessageImpl(message);", I get the same null results.
I can continue on successfully deal with the SOAPMessage, but how do I correctly interpret the SOAPMessage as an EbXMLMessageImpl?
Thanks.

After investigating this, the problem seems to be that com.sun.xml.messaging.jaxm.ebxml.EbXMLMessageImpl is using the namespace
NS_URI = "http://www.ebxml.org/namespaces/messageHeader";
instead of
NS_URI = "http://www.oasis-open.org/committees/ebxml-msg/schema/msg-header-2_0.xsd";
Subsequently, the same class attempts to parse timeStamp as a long, instead of an ISO8601 string.
