java cxf webservices 动态调用sap的一个服务地址，地址是带用户名和密码的权限。

String url = "http://xxx?sap-client=100";//地址为一个sap的服务，带有用户名和密码权限。
    JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory
            .newInstance();

    //此处应该增加什么代码以便通过用户名密码权限，现在没设置回报401访问不通过

    Client client = factory.createClient(url);




    try {

        QName opName = new QName("sdfdf", "sayHello");
        Object[] obj = client.invoke(opName, d);
        System.out.println("resp:" + obj[0]);

    } catch (Exception e) {
        e.printStackTrace();
