Help with a SOAP message

Question

Wondering if it's possible to send a byte array in a SOAP message?
This is what I originally have, but now I need to send an additional variable that's a byte array.
//create connection
      SOAPConnectionFactory soapConnFact = SOAPConnectionFactory.newInstance();
      SOAPConnection connection = soapConnFact.createConnection();
      //create message
      MessageFactory msgFact = MessageFactory.newInstance();
      SOAPMessage msg = msgFact.createMessage();
      //add SOAP action to header
      MimeHeaders headers = msg.getMimeHeaders();
      headers.addHeader("SOAPAction", "url");
      //create objects for message parts
      SOAPPart soapPart = msg.getSOAPPart();
      SOAPEnvelope envelope = soapPart.getEnvelope();
      SOAPBody body = envelope.getBody();
      //populate body and create main element and namespace
      SOAPElement bodyElement = body.addChildElement(envelope.createName("Name", "Name", "http://tempuri.org/"));
      //add content
      bodyElement.addChildElement("username").addTextNode(_user);
      bodyElement.addChildElement("password").addTextNode(_password);
      bodyElement.addChildElement("xmlStr").addTextNode(_xml);
      //save message
      msg.saveChanges();

The whole point of the Base64 encoding was so that you would have a string. So your question about whether you can now send a byte array indicates a serious degree of incomprehension. Could you please review the entire thread before posting again?
And yes, XML is a text format. You are using XML are you not? Therefore you need text data.
