问题 I want to start an application which will use ajax push, however the web server should be configured properly and i don't know how to start on server side components. I wanted to start with dojo's cometd and then read some blogs saying that activeMQ is older and flag carrier on ajax push thing, but there was also another blog saying that it is very hard to set-up and get it work. Now i'm confused before giving a start, please tell me my way :) What's the optimum way of configuring an ajax

问题 I am deploying CometD-3.0.1 in jetty-9.2.2. I have my own filters which I want to call for every request. I have specified those filters in the web.xml in particular order. But with WebSocket, containers have to find a way to handle the upgrade request. In Jetty, this is done by a servlet filter that is always added as first filter by a ServletContainerInitializer. So in my case, a upgrade request will never hit my filter, because the WS filter that's in the front of the chain will do the

问题 I'm having a problem with my CometD Application. It looks like its creating multiple instances of the Bayeux Server. My configuration Files look like the following and i'm using Web Sockets as Transport/GigaSpaces to deploy the Application (which uses its own embedded jetty Server). Just wondering if I've misconfigured something in the following setup? WEB.XML: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml

问题 I am developing WinForm desktop application. I am successfully handshaking with CometD server and then sending change requests to the server. I am sure that requests are successfully received and request command is done by the server and finally expecting that there is a State Changed message by the CometD server. However, there is no message received to me onMessage() method. Does anyone know why? Any suggestions? public void getCometDAuthenticationRequest(HttpWebRequest request) { request =

问题 I am working on a Spring-MVC based web-app which uses Cometd for chat purposes. For real-time management of which user is online, we are sending notifications when the user is online. So when window is closed, then notifications don't appear and after 30 seconds it is determined that the user is offline or not reachable. Now the problem happens when user is over multiple browsers. Lets just keep it for 2 now. So, after 10 minutes we are setting user status to 'Away from Keyboard'(AFK). But if

问题 I'm trying to use cometd as a servlet to dropwizard but BayeuxServer doesn't seem to get injected in my service. I'm adding my two servlets as so (note, I'm not using web.xml so I'm defining the params myself): cometdConfig.put("services", MyService.class.getCanonicalName()); System.out.print("OrderService name: " + MyService.class.getCanonicalName()); environment.addServlet(AnnotationCometdServlet.class, "/cometd/*").addInitParams(cometdConfig).setInitOrder(1); environment.addServlet(new

问题 I'm trying to get started with cometd (http://cometd.org/) and jetty 6 or 7, but I seem to be having problems. I've got an ant script that packages my code up into a war with the cometd 1.1.1 binaries and jetty binaries that are appropriate to the version of jetty I deploy the war to (so 7.1.2.v20100523 binaries when I deploy to jetty 7.1.2.v20100523 and 6.1.24 when I deploy to 6.1.24). I first tried getting a setup with version 7.1.2.v20100523, but when I tried to deploy I got a very long

问题 Our application that will act as a client needs to subscribe to an external system that uses cometd to deliver unsolicited notifications to clients. Is there a way to achieve this without cometd libraries (via apache HttpClient for instance)? Java version mismatch is the problem - we use 1.6, but cometd require 1.7 or higher. thanks in advance 回答1: CometD 2.x, albeit not under development anymore, supports back to JDK 5. The underlying protocol (Bayeux) is the same, so I expect a CometD 2.x

问题 I am working on an Android application in which I am trying to initialize a LongPollingTransport as mentioned below. But I am getting an error from Jetty scheduler. I am not calling the Jetty Scheduler class myself. How can I fix this. Any help would be nice. Code : public class ConsoleChatClient { private volatile String nickname = "kernel"; private volatile BayeuxClient client; private final ChatListener chatListener = new ChatListener(); private final MembersListener membersListener = new
