Jetty ServerのセッションがNullです

セッションを見ているサーブレットでhello world Jettyプロジェクト（Jetty 9.3.6.v20151106を使用）を実装しようとしています。しかし、私のコードが実行されると、私はセッションを見たり、クッキーを保存することができません。私はthis stackoverflowの質問でトラブルシューティングを支援し、シンプルなBaseServletを実装することをお勧めしましたが、BaseServletを実行するたびに「セッションなし」を出力します。私はいくつかの設定が欠けていますか？ここでJetty ServerのセッションがNullです

は私のHelloWorld.javaクラスである：ここで

import org.eclipse.jetty.server.session.SessionHandler; 
import org.eclipse.jetty.servlet.ServletContextHandler; 
import org.eclipse.jetty.servlet.ServletHandler; 
import org.eclipse.jetty.servlet.ServletHolder; 

public class HelloWorld { 

public static void main(String[] args) throws Exception { 
    //Create the server 
    Server server = new Server(); 

    // Configure for Http 
    HttpConfiguration http_config = new HttpConfiguration(); 
    http_config.setSecureScheme("https"); 
    http_config.setSecurePort(8443); 
    http_config.setOutputBufferSize(32768); 

    ServerConnector http = new ServerConnector(server, 
      new HttpConnectionFactory(http_config)); 
    int http_port = 12043; 
    http.setPort(http_port); 
    http.setIdleTimeout(30000); 
    server.addConnector(http); 

    //Add ServletContextHandler 
    ServletContextHandler servletContextHandler = new ServletContextHandler(
      ServletContextHandler.SESSIONS); 
    servletContextHandler.setContextPath("/"); 

    SessionManager sessionManager = new HashSessionManager(); 
    sessionManager.setMaxInactiveInterval(60 * 15); //session time out of 15 minutes 
    HashSessionIdManager idManager = new HashSessionIdManager(); 
    sessionManager.getSessionCookieConfig().setName("JSESSIONID_" + Integer.toString(http_port)); 
    sessionManager.setSessionIdManager(idManager); 
    server.setSessionIdManager(idManager); 
    SessionHandler sessionHandler = new SessionHandler(sessionManager); 
    servletContextHandler.setSessionHandler(sessionHandler); 
    server.setHandler(servletContextHandler); 

    //Add BaseServlet 
    ServletHolder holder = new ServletHolder(new BaseServlet()); 
    servletContextHandler.addServlet(holder, "/*"); 

    //Start the server 
    server.start(); 
    System.out.println("SERVER DUMP AFTER START" + server.dump()); 

    // The use of server.join() the will make the current thread join and 
    // wait until the server is done executing. 
    // See http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#join() 
    server.join(); 
    } 
}

メーリングリスト桟橋ユーザの人々と話をした後、私はなるために自分のコードを変更：

出力され

public static void main(String[] args) throws Exception { 
// Create the server 
Server server = new Server(12043); 

// Add ServletContextHandler 
ServletContextHandler servletContextHandler = new ServletContextHandler(
ServletContextHandler.SESSIONS); 
servletContextHandler.setContextPath("/"); 

server.setHandler(servletContextHandler); 

// Add BaseServlet 
ServletHolder holder = new ServletHolder(new BaseServlet()); 
servletContextHandler.addServlet(holder, "/*"); 

// Start the server 
server.start(); 
System.out.println("SERVER DUMP AFTER START" + server.dump()); 

server.join(); 

}

：要求=リクエスト（GET // localhostを：12043 /）968bbe8 応答@ = HTTP/1.1 200 日：木、2016年6月2日夜01時00分04秒GMT = falseを何のセッションを作成していない

呼び出しrequest.getSession（false）はセッションを作成しないため、期待されています。以前に作成されている場合のみ返します。
