Grizzly服务器的基本身份验证

我已将此示例应用到我的应用程序中：

I have implemented this example into my application:

https-clientserver-grizzly

这是 Server.java ：

public class Server {

    private static HttpServer webServer;

    public static final URI BASE_URI = getBaseURI();
    public static final String CONTENT = "JERSEY HTTPS EXAMPLE\n";

    private static URI getBaseURI() {
        return UriBuilder.fromUri("https://localhost/").port(getPort(4463)).build();
    }

    private static int getPort(int defaultPort) {
        String port = System.getProperty("jersey.test.port");
        if (null != port) {
            try {
                return Integer.parseInt(port);
            } catch (NumberFormatException e) {
            }
        }
        return defaultPort;
    }

    protected static void startServer() {

        // add Jersey resource servlet
        WebappContext context = new WebappContext("context");
        ServletRegistration registration = 
                context.addServlet("ServletContainer", ServletContainer.class);
        registration.setInitParameter("com.sun.jersey.config.property.packages",
                "com.sun.jersey.samples.https_grizzly.resource;com.sun.jersey.samples.https_grizzly.auth");

        // add security filter (which handles http basic authentication)
        registration.setInitParameter(ResourceConfig.PROPERTY_CONTAINER_REQUEST_FILTERS,
                SecurityFilter.class.getName());

        // Grizzly ssl configuration
        SSLContextConfigurator sslContext = new SSLContextConfigurator();

        // set up security context
        sslContext.setKeyStoreFile("./keystore_server"); // contains server keypair
        sslContext.setKeyStorePass("asdfgh");
        sslContext.setTrustStoreFile("./truststore_server"); // contains client certificate
        sslContext.setTrustStorePass("asdfgh");

        try {

            webServer = GrizzlyServerFactory.createHttpServer(
                    getBaseURI(),
                    null,
                    true,
                    new SSLEngineConfigurator(sslContext).setClientMode(false).setNeedClientAuth(true)
            );

            // start Grizzly embedded server //
            System.out.println("Jersey app started. Try out " + BASE_URI + "\nHit CTRL + C to stop it...");
            context.deploy(webServer);
            webServer.start();

        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }
    }

    protected static void stopServer() {
        webServer.stop();
    }

    public static void main(String[] args) throws InterruptedException, IOException {
        startServer();

        System.in.read();
    }
}

但是我决定只启用基本身份验证（不是SSl）需要验证）

However I decided to enable just Basic Authentication (not SSl authentication needed)

我更改了那部分：

UriBuilder.fromUri("http://localhost/").port(getPort(4463)).build();

我评论了该行的部分：

SSLConfig sslConfig = new SSLConfig();

直到该行：

System.out.println("Jersey app started. Try out " + BASE_URI + "\nHit CTRL + C to stop it...");    

但是我收到了这个错误：

However I get that error:

com.sun.grizzly.DefaultProtocolChain executeProtocolFilter

如何编写代码只需要在grizzly进行基本身份验证吗？

How can I write a code that just needs basic authentication at grizzly?
