上一篇说了SOAP消息的创建，那么创建好了的SOAP消息要怎么发送给服务端呢？
public class SoapTest {private String wsdlUri = "http://localhost:9999/ns?wsdl";private String ns = "http://lenve.server/";@Testpublic void test3() {try {// 1.创建服务ServiceURL url = new URL(wsdlUri);QName sname = new QName(ns, "MyServerImplService");Service service = Service.create(url, sname);// 2.创建DispatchDispatch<SOAPMessage> dispatch = service.createDispatch(new QName(ns,"MyServerImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);//3.创建SOAPMessageSOAPMessage msg = MessageFactory.newInstance().createMessage();SOAPBody body = msg.getSOAPPart().getEnvelope().getBody();//4.创建QName来指定消息中传递的数据QName ename = new QName(ns,"add","ns");SOAPBodyElement ele = body.addBodyElement(ename);ele.addChildElement("a").setValue("3");ele.addChildElement("b").setValue("6");//5.通过Dispatch传递消息，同时收到响应消息SOAPMessage response = dispatch.invoke(msg);response.writeTo(System.out);Document doc = response.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();String str = doc.getElementsByTagName("addResult").item(0).getTextContent();System.out.println();System.out.println(str);} catch (SOAPException | IOException e) {e.printStackTrace();}}
}客户端输出：
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><S:Body><ns2:addResponse xmlns:ns2="http://lenve.server/"><addResult>9</addResult></ns2:addResponse></S:Body></S:Envelope>

成功调用了服务端程序。代码中先定义了两个变量，第一个是地址，这个不用多解释，第二个是命名空间，这是从地址所表示的页面中得到的。
