I am using jetty 9 in embedded mode and even though i have given a threadpool of 500 the server still just handle one request at a time.
What am i missing ?
JAVA CODE:
// here i expect all thread name log to print instantaneously but they print one by one
public class Main { public static void main(String[] arg) throws Exception { ExecutorThreadPool executorThreadPool = new ExecutorThreadPool(Executors.newFixedThreadPool(500)); final Server server = new Server(executorThreadPool); final ServerConnector connector0 = new ServerConnector(server); connector0.addBean(executorThreadPool); connector0.setPort(8080); server.setHandler(new HelloHandler()); server.setConnectors(new Connector[] {connector0}); server.setDumpAfterStart(true); server.start(); server.join(); } } class HelloHandler extends AbstractHandler { public void handle(String target,Request baseRequest,HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException { try { System.out.println("Thread Name+" + Thread.currentThread().getName()); Thread.sleep(3000l); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } response.setContentType("text/html;charset=utf-8"); response.setStatus(HttpServletResponse.SC_OK); baseRequest.setHandled(true); response.getWriter().println("<h1>Hello World</h1>"); } } POM.XML
