Simple Java HTTPS server

I need to set up a really lightweight HTTPS server for a Java application. It's a simulator that's being used in our development labs to simulate the HTTPS connections accepted by a piece of equipment in the wild. Because it's purely a lightweight development tool and isn't used in production in any way at all, I'm quite happy to bypass certifications and as much negotiation as I can.

I'm planning on using the HttpsServer class in Java 6 SE but I'm struggling to get it working. As a test client, I'm using wget from the cygwin command line (wget https://[address]:[port]) but wget reports that it was "Unable to establish SSL connection".

If I run wget with the -d option for debugging it tells me "SSL handshake failed".

I've spent 30 minutes googling this and everything seems to just point back to the fairly useless Java 6 documentation that describes the methods but doesn't actually talk about how to get the darn thing talking or provide any example code at all.

Can anyone nudge me in the right direction?

Solution

What I eventually used was this:

try {
    // Set up the socket address
    InetSocketAddress address = new InetSocketAddress(InetAddress.getLocalHost(), config.getHttpsPort());

    // Initialise the HTTPS server
    HttpsServer httpsServer = HttpsServer.create(address, 0);
    SSLContext sslContext = SSLContext.getInstance("TLS");

    // Initialise the keystore
    char[] password = "simulator".toCharArray();
    KeyStore ks = KeyStore.getInstance("JKS");
    FileInputStream fis = new FileInputStream("lig.keystore");
    ks.load(fis, password);

    // Set up the key manager factory
    KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
    kmf.init(ks, password);

    // Set up the trust manager factory
    TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
    tmf.init(ks);

    // Set up the HTTPS context and parameters
    sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
    httpsServer.setHttpsConfigurator(new HttpsConfigurator(sslContext) {
        public void configure(HttpsParameters params) {
            try {
                // Initialise the SSL context
                SSLContext c = SSLContext.getDefault();
                SSLEngine engine = c.createSSLEngine();
                params.setNeedClientAuth(false);
                params.setCipherSuites(engine.getEnabledCipherSuites());
                params.setProtocols(engine.getEnabledProtocols());

                // Get the default parameters
                SSLParameters defaultSSLParameters = c.getDefaultSSLParameters();
                params.setSSLParameters(defaultSSLParameters);
            } catch (Exception ex) {
                ILogger log = new LoggerFactory().getLogger();
                log.exception(ex);
                log.error("Failed to create HTTPS port");
            }
        }
    });
    LigServer server = new LigServer(httpsServer);
    joinableThreadList.add(server.getJoinableThread());
} catch (Exception exception) {
    log.exception(exception);
    log.error("Failed to create HTTPS server on port " + config.getHttpsPort() + " of localhost");
}

To generate a keystore:

$ keytool -genkeypair -keyalg RSA -alias self_signed -keypass simulator \
  -keystore lig.keystore -storepass simulator
