java调用webservice的.asmx接口的使用步骤

例：接口地址：Http://IP地址/xxx/service/xxx/xxxx.asmx
	方法名：test
	参数类型：string 

String s = clientUtil.test("http://IP地址/xxx/service/xxx/xxxx.asmx", "test","test");

public static String test(String Url, String methodName, String str) throws Exception {
        String ref = null;
        // webService链接地址
        String url = Url;
        //获取域名地址，server定义的
        String soapaction = "http://tempuri.org/";
		
        Service service = new Service();
        try {
            Call call = (Call) service.createCall();
            call.setTargetEndpointAddress(url);
            // 设置要调用哪个方法
            call.setOperationName(new QName(soapaction, methodName));
            // 设置要传递的参数名
           call.addParameter(new QName(soapaction,"str"),org.apache.axis.encoding.XMLType.XSD_STRING,
       javax.xml.rpc.ParameterMode.IN);
            // 提供标准类型 有addParameter就必须有setReturnType
            call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
            call.setUseSOAPAction(true);
            call.setSOAPActionURI(soapaction + methodName);
            // 调用方法并传递参数
			ref = (String) call.invoke(new Object[]{str});
           return ref;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return ref;
    }
