Creating EbXML from a stream

Question

I want to be able to create an EbXMLMessageImpl object from a stream, and I am running into errors.
The following code makes teh EbXMLMessageImpl into a stream, and then I want to put the stream back into an EbXMLMessageImpl. (I am testing what I will have to do if I receive a stream and needed to convert it to a EbXMLMessageImpl object.)
Am I setting the MIME headers correctly? Can the stream represent a multipart/related message?
Here is a small sample of the code:
public static void main(String [] args)
try
EbXMLMessageFactoryImpl factory = new EbXMLMessageFactoryImpl();
// ProviderConnectionFactory factory = ProviderConnectionFactory.newInstance();
// ProviderConnection connection = factory.createConnection();
// MessageFactory fact = connection.createMessageFactory("ebxml");
EbXMLMessageImpl message = (EbXMLMessageImpl)factory.createMessage();
EbXMLMessageImpl ebxmlMsg = message;
ByteArrayInputStream stream = new ByteArrayInputStream("<? xml version='1.0' ?><BEGIN></BEGIN>".getBytes());
message.setAction("dasdf");     ebxmlMsg.setSender(new Party("[email protected]"));
     ebxmlMsg.setReceiver(new Party("edwardbying@[email protected]"));
     Service service = new Service("SupplierOrderProcessing");
     ebxmlMsg.setRefToMessageId("[email protected]");
     ebxmlMsg.setCPAId("http://example.com/cpas/ourcpawithyou.xml");
     ebxmlMsg.setConversationId("20001209-133003-28572");
     ebxmlMsg.setService(service);
     ebxmlMsg.setAction("NewOrder");
     Manifest manifest = new Manifest("manifest", "1.0");
     Reference ref = new Reference("pay01", "cid:pay01",
                    "http://regrep.org/gci/purchaseorder");
     Schema schema = new Schema(
                    "http://regrep.org/gci/purchaseorder.xsd",
                    "1.0");
     ref.setSchema(schema);
     Description desc = new Description("en-us");
     desc.setText("PurchaseOrder for widgets");
     ref.setDescription(desc);
     manifest.addReference(ref);
     ebxmlMsg.setManifest(manifest);
SOAPPart part = message.getSOAPPart();
SOAPEnvelope envelope = part.getEnvelope();
envelope.getHeader().detachNode();
SOAPHeader header = envelope.addHeader();
Name eb_messageHeader = envelope.createName("MessageHeader","eb","http://www.ebxml.org/namespaces/messageHeader");
header.addHeaderElement(eb_messageHeader);
// message.saveChanges();
AttachmentPart attachment = message.createAttachmentPart("<? xml version='1.0' ?><BEGIN></BEGIN>", "text/plain");
attachment.setContentType("text/xml");
message.addAttachmentPart(attachment);
ByteArrayOutputStream out = new ByteArrayOutputStream();
message.writeTo(out);
message.writeTo(System.out);
System.out.println(System.getProperty("user.dir"));
FileOutputStream fileout= new FileOutputStream("file.dat");
message.writeTo(fileout);
fileout.flush();
fileout.close();
ByteArrayInputStream in = new ByteArrayInputStream(out.toByteArray());
MimeHeaders mimeheader = new MimeHeaders();
LineNumberReader reader = new LineNumberReader(new InputStreamReader( new ByteArrayInputStream(out.toByteArray())));
String line = reader.readLine();
System.out.println(line);
String bondary = line.substring(2, line.length());
System.out.println(bondary);
mimeheader.addHeader("Content-type","multipart/related; boundary=\""+bondary + "\"");
EbXMLMessageImpl impl = new EbXMLMessageImpl(mimeheader,in);
}catch(Exception e)
e.printStackTrace();
System.exit(0);

Hi,
I am also facing a problem creating an ebXMLMessageImpl object from a stream.
The thing I am doing differently to read the headers : I create a MimeMessage from the stream and get the headers from there and then populate MimeHeaders object with it.
I then use the MimeHeaders and the input stream to create
a ebXMLMessageImpl object.
Among other exceptions I get during my trial and error, I am getting an exception
Warning: Error occurred using JAXP to load a SAXParser. Will use Aelfred instead
Exception in thread "main" java.lang.ClassCastException: com.sun.xml.messaging.saaj.soap.dom4j.TextImpl at com.sun.xml.messaging.jaxm.ebxml.EbXMLMessageImpl.fillInHeaders(EbXML
MessageImpl.java:137)
at com.sun.xml.messaging.jaxm.ebxml.EbXMLMessageImpl.<init>(EbXMLMessage
Impl.java:117)
If anybody knows a solution to create a ebXML message from an input stream - or know how I can solve this exception - please reply
Thanks,
Anant.
