#30273 — Sending SOAP through sockets

I try to send soap message from client written by me to server also written by me through sockets.

I'll try to paste only important code that should do that (communication between server and client is ok - I can send String object):

    // Client

    /* Soap */
    MessageFactory factory = MessageFactory.newInstance();
	SOAPMessage soapMsg = factory.createMessage();
	SOAPPart part = soapMsg.getSOAPPart();
			 
	SOAPEnvelope envelope = part.getEnvelope();
	SOAPHeader header = envelope.getHeader();
	SOAPBody body = envelope.getBody();
			 
	header.addTextNode("SomeText");
	header.setValue("SomeValue");
			 
	SOAPBodyElement element = body.addBodyElement(envelope.createName("JAVA", "training", "aaa"));
	element.addChildElement("XXX").addTextNode("YYY");
			 
	SOAPBodyElement element1 = body.addBodyElement(envelope.createName("JAVA", "training", "bbb"));
	element1.addChildElement("Spring").addTextNode("TrainingonSpring");
    /* Soap */

    String soapMessage = soapMsg.toString();

    Socket s = new Socket(serverHostname, 10007);
    PrintStream out = new PrintStream(s.getOutputStream(), true);

    out.println(soapMessage);



    // Server
    ServerSocket serverSocket = new ServerSocket(10007);
    Socket socket = serverSocket.accept(); 
    BufferedReader in = new BufferedReader(new InputStreamReader( socket.getInputStream())); 
    String inputLine = in.readLine(); 
    // I've read Soap as a String and I want to change it to SoapMessage

    InputStream is = new ByteArrayInputStream(inputLine.getBytes());
    SOAPMessage soap = MessageFactory.newInstance().createMessage(null, is);

    // I try to print for example Header Value to system output
    System.out.println(soap.getSOAPHeader().getValue().toString());


   ///////////////////

I have a lot of errors. ;(

See if you can find ANY soap application with source.  For example
Amazon AWS, then watch it operate with a packet sniffer and by tracing
the code until you understand generally how SOAP works.
You might also bring your background understanding up to snuff by
reading a text.  See http://mindprod.com/jgloss/soap.html

The first thing that hits me is my understanding is SOAP sits atop
HTTP.  Otherwise it is going to have trouble tunneling through
firewalls without special setup. You are trying to use raw sockets.

I have been having trouble with uploads. That page is out of date.
Hopefully the problem will be fixed some time on wed.
