My code is
      MessageFactory factory = MessageFactory.newInstance();
      SOAPMessage message = factory.createMessage();

      // The message contains a SOAPPart object, so you use
      // the getSOAPPart method of message to retrieve it:
      SOAPPart soapPart = message.getSOAPPart();

      SOAPEnvelope envelope = soapPart.getEnvelope();

      SOAPHeader header = envelope.getHeader();
      SOAPBody body = envelope.getBody();
      header.detachNode();
      Name bodyName = envelope.createName("GetLastTradePrice", "ztrade",
                                          "http://wombat.ztrade.com");
      SOAPBodyElement bodyElement = body.addBodyElement(bodyName);

      Name name = envelope.createName("symbol", "ztrade",
                                      "http://wombat.ztrade.com");
      SOAPElement symbol = bodyElement.addChildElement(name).addTextNode("SUNW");

      URL url = new URL("http://3.209.126.224:5555/GERenaissance");
      System.out.println("i am after the URL 22222 connection");
      System.setProperty("javax.xml.soap.SOAPConnectionFactory",
          "com.sun.xml.messaging.saaj.client.p2p.HttpSOAPConnectionFactory");
      System.setProperty("javax.xml.soap.SOAPConnection",
          "com.sun.xml.messaging.saaj.client.p2p.HttpSOAPConnection");
      System.out.println("after setting the property");
      SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.
          newInstance();
      System.out.println("soapConnectionFactory" + soapConnectionFactory);
      //Now you can use soapConnectionFactory to create a SOAPConnection object.


      HttpSOAPConnection connection =(HttpSOAPConnection) soapConnectionFactory.createConnection();
      System.out.println("connection 1234 fsdgfsdgfg" + connection);
      System.out.println("after making connection ");
      SOAPMessage resp = connection.call(message, url);
      System.out.println("the response is " + resp);
