Grizzly with TLS - Handshaking issue

问题:

I'm currently trying to secure my Grizzly HTTP-Server with SSL (which should be quite easy according to tutorials and examples) - server side only. So first I've downloaded the UnlimitedJCEPolicy from Orcale in order to be able to support strong TLS algorithms. Then I've created a new keystore file with the keytool and the following command:

keytool -keyalg rsa -keysize 2048 -genkey -keystore .\keystore_server.jks -alias server -dname "..."

Finally I set up my Server with the following Java code:

    //Create Http Server
    HttpServer server = new HttpServer();

    //Configure and register listener
    NetworkListener adminListener = new NetworkListener("admin", "localhost", 19241);

    SSLContextConfigurator configurator = new SSLContextConfigurator();
    URL url = configurator.getClass().getResource("/keystore_server.jks");
    if(url == null) throw new Error("Could not get Keystore!");
    configurator.setKeyStoreFile(url.getFile());
    configurator.setKeyStorePass("store");
    configurator.setKeyPass("key");
    configurator.setSecurityProtocol("TLS");


    SSLContext context = configurator.createSSLContext();
    SSLEngineConfigurator engineConfigurator = new SSLEngineConfigurator(context);
    engineConfigurator.setWantClientAuth(false);
    engineConfigurator.setClientMode(true);
    engineConfigurator.setNeedClientAuth(false);


    adminListener.setSSLEngineConfig(engineConfigurator);
    adminListener.setSecure(true);

    server.addListener(adminListener);

    Endpoint endpoint = new Endpoint();

    EndpointApplication application = new EndpointApplication(endpoint);

    HttpHandler httpHandler = RuntimeDelegate.getInstance().createEndpoint(application, HttpHandler.class);
    server.getServerConfiguration().addHttpHandler(httpHandler, "/test");

    server.start();

Thanks to Warren, I resolved the first issue not explicitly specifying HTTPS as the protocol to use. However, there is now another problem. Here is the log:

Is anybody familiar with this type of error?

回答1:

I've had this exact same problem, when using -Djavax.net.debug=all command line parameter I found this log line:

Grizzly(2) SelectorRunner, fatal error: 80: problem unwrapping net record

Based on the comments by alexey I changed the code to:

engineConfigurator.setClientMode(false);
engineConfigurator.setNeedClientAuth(false);

After this change, the fatal error dissapears and I am able to access the application.wadl over https with a browser.

I've lost quite a bit of time searching for a solution, it would be nice if Grizzly reported this problem in a more readable, understandable way.
