SslConnector.java interface has been changed in the newest Jetty 7.3.1.v20110307.
Almost all off the methods have been marked as deprecated without mentioni
Building on your own answer:
Server server = new Server();
// Encrypt the connection using a valid certificate/keystore
SslContextFactory sslContextFactory = new SslContextFactory("path/keystore.jks");
sslContextFactory.setKeyStorePassword("password");
// Create a new SocketConnector at port 443, which is the default port for
// HTTPS web pages (no port number needs to be specified in the browser).
SslSocketConnector sslConnector = new SslSocketConnector(sslContextFactory);
sslConnector.setPort(443);
// Add the SocketConnector to the server
server.setConnectors(new Connector[] {sslConnector});
