How can I configure Simple Framework to require SSL client authentication? - ssl

Question

I am writing an HTTP server using the Simple Framework and would like to require clients to present a valid certificate signed by my certificate authority in order to establish a connection.
I have the following bare-bones server written. How can I modify this code to require client certificate authentication for all SSL connections?
public static void main(String[] args) throws Exception {
Container container = createContainer();
Server server = new ContainerServer(container);
Connection connection = new SocketConnection(server);
SocketAddress address = new InetSocketAddress(8443);
KeyManagerFactory km = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
KeyStore serverKeystore = KeyStore.getInstance(KeyStore.getDefaultType());
try(InputStream keystoreFile = new FileInputStream(SERVER_KEYSTORE_PATH)) {
serverKeystore.load(keystoreFile, "asdfgh".toCharArray());
}
km.init(serverKeystore, SERVER_KS_PASSWORD.toCharArray());
TrustManagerFactory tm = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
KeyStore caKeystore = KeyStore.getInstance(KeyStore.getDefaultType());
try(InputStream caCertFile = new FileInputStream(CA_CERT_PATH)) {
caKeystore.load(caCertFile, CA_KS_PASSWORD.toCharArray());
}
tm.init(caKeystore);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(km.getKeyManagers(), tm.getTrustManagers(), null);
connection.connect(address, sslContext);
}

Try this
public class MyServer implements org.simpleframework.transport.Server {
private Server delegateServer;
public MyServer(Server delegateServer){
this.delegateServer = delegateServer;
}
public void process(Socket socket){
socket.getEngine().setNeedClientAuth(true);
delegateServer.process(socket);
}
}
