webService调用几种方法

    //第一种方法           RPCServiceClient client = new RPCServiceClient();             Options options = client.getOptions();             String url = "http://......./conf/xcloudwebs.wsdl";  //wsdl地址           EndpointReference end = new EndpointReference(url);             options.setTo(end);                        HashMap contMap = new HashMap();contMap.put("key", "10bdaef151f30ba3eba5cfdf04edeaf3");//帐号contMap.put("secret", "d671b6c0b850564f4dbda5c12d683c20");//密码JSONArray json = JSONArray.fromObject(contMap);                       Object[] obj = new Object[]{ json.toString()};//参数           Class[] classes = new Class[] { String.class }; //类型           QName qname = new QName("urn:xcloudwebs", "xcloudwebs-api");//命名空间和方法名           System.out.println(qname.toString());           String result = (String) client.invokeBlocking(qname, obj,classes)[0];            System.out.println(result);              //第二种方法           ServiceClient sc = new ServiceClient();           Options opts = new Options();            String url = "http://......./conf/xcloudwebs.wsdl";  //wsdl地址           EndpointReference end = new EndpointReference(url);           opts.setTo(end);           opts.setAction("xcloudwebs-api");           sc.setOptions(opts);                       OMFactory fac = OMAbstractFactory.getOMFactory();             OMNamespace omNs = fac.createOMNamespace("urn:xcloudwebs", "");             OMElement method = fac.createOMElement("xcloudwebs-api",omNs);             OMElement value = fac.createOMElement("params",omNs);                      HashMap contMap = new HashMap();contMap.put("key", "10bdaef151f30ba3eba5cfdf04edeaf3");//帐号contMap.put("secret", "d671b6c0b850564f4dbda5c12d683c20");//密码JSONArray json = JSONArray.fromObject(contMap);            value.setText(json.toString());           method.addChild(value);            OMElement res = sc.sendReceive(method);           res.getFirstElement().getText();             System.out.println(res.getFirstElement().getText());
