Create soap client

// Web Service  

String url = "http://red.cse.yorku.ca:4413/axis/YYZ.jws";

// 1. Create a SOAP message

SOAPMessage msg = MessageFactory.newInstance().createMessage();

// 2. get header

MimeHeaders header =  msg.getMimeHeaders();

header.addHeader("SOAPAction", "");

// 3. get soap part

SOAPPart soap = msg.getSOAPPart();

// 4. get soap envelop

SOAPEnvelope envelop = soap.getEnvelope();

// 5. get soap body

SOAPBody body = envelop.getBody();

// 6. add body element

body.addChildElement("getName").addChildElement("itemNumber").addTextNode("2002H123");

// 7. open soap connection

SOAPConnection sc = SOAPConnectionFactory.newInstance().createConnection();

// 8. send soap request

SOAPMessage soapResponse = sc.call(msg, new URL(url));

// 9. close soap connection

sc.close();

System.out.println("SOAP Request ");

// 10. retrieve the response node

// 11. print out the Node text
