I'm trying to use websockets within my local Glassfish 3.1.2 server installation. I'm using Grizzly 2.2 in my Maven project :
<dependency> <groupId>org.glassfish.grizzly</groupId> <artifactId>grizzly-websockets</artifactId> <version>2.2</version> </dependency> WebSocketsServlet.java
import org.glassfish.grizzly.Grizzly; import java.util.logging.Logger; import org.glassfish.grizzly.websockets.WebSocketEngine; import javax.servlet.ServletConfig; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; public class WebSocketsServlet extends HttpServlet { private static final Logger logger = Grizzly.logger(WebSocketsServlet.class); private final VideoSharingApplication app = new VideoSharingApplication(); ///自定义类，继承自WebSocketApplication @Override public void init(ServletConfig config) throws ServletException { logger.log(Level.SEVERE, "registering"); WebSocketEngine.getEngine().register(config.getServletContext().getContextPath() + "/videosharing", app); } //// void |
register(String name, WebSocketApplication app) Deprecated. |
void |
register(WebSocketApplication app) |
@Override public void destroy() { WebSocketEngine.getEngine().unregister(app); } } VideoSharingWebSocket.java
import java.util.logging.Logger; import org.glassfish.grizzly.websockets.DefaultWebSocket; import org.glassfish.grizzly.websockets.ProtocolHandler; import org.glassfish.grizzly.websockets.WebSocketListener; import org.glassfish.grizzly.Grizzly; public class VideoSharingWebSocket extends DefaultWebSocket { private static final Logger logger = Grizzly.logger(VideoSharingWebSocket.class); public VideoSharingWebSocket(ProtocolHandler handler, WebSocketListener... listeners) { super(handler, listeners); ///} }
VideoSharingApplication.java
import java.util.logging.Level; import java.util.logging.Logger; import org.glassfish.grizzly.Grizzly; import org.glassfish.grizzly.websockets.ProtocolHandler; import org.glassfish.grizzly.websockets.WebSocket; import org.glassfish.grizzly.websockets.WebSocketApplication; import org.glassfish.grizzly.websockets.WebSocketListener; import org.glassfish.grizzly.http.HttpRequestPacket; public class VideoSharingApplication extends WebSocketApplication { private static final Logger logger = Grizzly.logger(VideoSharingApplication.class); @Override public WebSocket createSocket(ProtocolHandler handler, WebSocketListener... listeners) { logger.log(Level.SEVERE, "createSocket"); return new VideoSharingWebSocket(handler, listeners); } @Override public boolean isApplicationRequest(HttpRequestPacket request) { logger.log(Level.SEVERE, "isApplicationRequest"); return "/videosharing".equals(request.getRequestURI()); //Checks application specific criteria to determine if this application can process the Request as a WebSocket connection.检查应用程序特定的标准来确定这个应用程序可以处理该请求作为一个WebSocket连接。 } @Override public void onMessage(WebSocket socket, String data) { logger.log(Level.SEVERE, "onMessage"); for (WebSocket webSocket : getWebSockets()) { if (socket != webSocket) { webSocket.send(data); } } } } I enabled websockets support in Glassfish with this command :
asadmin set configs.config.server-config.network-config.protocols.protocol.http-listener-1.http.websockets-support-enabled=true Client code, app.js :
var network = function () { return { initialize: function() { var url = 'ws://localhost:8080/monApp/videosharing'; var websocket = new WebSocket(url); websocket.name = APP.id; websocket.onopen = function(evt) { alert('onopen'); }; websocket.onerror = function(evt) { alert('onerror'); }; websocket.onmessage = function (evt) { alert('onmessage'); var command = JSON.parse(evt.data); /// if (command.type == "pause") { APP.pauseVideo(); } else if (command.type == "play") { APP.playVideo(); } else if (command.type == "seeked") { APP.seekVideo(command.currentTime); } else { alert("Unknown command " + command); } }; websocket.onclose = function() { alert('onclose'); }; }, send: function(command) { websocket.send(command); } } }; var APP = { id: Math.floor(Math.random() * 10000), network: network(), // Cannot use 'this' here after updating window.onload (see below) initialize: function () { APP.network.initialize(); var video = APP.getVideo(); video.addEventListener('play', function (event) { alert('play'); var command = { type: "play" }; APP.network.send(JSON.stringify(command)); }, false); video.addEventListener('pause', function (event) { alert('pause'); var command = { type: "pause" }; APP.network.send(JSON.stringify(command)); }, false); video.addEventListener('seeked', function (event) { alert('seeked'); var command = { type: "seeked", currentTime: APP.getVideo().currentTime }; APP.network.send(JSON.stringify(command)); }, false); }, getVideo: function () { return document.getElementsByTagName("video")[0]; }, pauseVideo: function () { var video = this.getVideo(); video.pause(); }, playVideo: function () { var video = this.getVideo(); video.play(); }, seekVideo: function (currentTime) { var video = this.getVideo(); video.currentTime = currentTime; } }; window.onload = APP.initialize; I'm testing this in Chrome 18.0.1025.165 in a Mac. At page loading I get this error :
Unexpected response code: 405 In the server logs there is no error and only my "registering" (WebSocketsServlet) log is displayed.
Do you have any suggestion ?
Thank you in advance.
Best regards.

GlassFish 3.1.2 uses Grizzly 1.9.46. Grizzly 2.x is incompatible with that version of GlassFish. You'll need to use the 1.9.46 or later versions of 1.9 with 3.1.2. |

What is GlassFish Server 3.1.2?
GlassFish Server 3.1.2 is the successor of the earlier 3.0.x releases, offering a modular runtime based OSGi now with fully-featured clustering with centralized administration of multiple clusters and high availability of stateful components. Developers also benefit from the simplified programming model and productivity improvements offered by Java EE 6.
This version has hundreds of bug fixes as well as updated versions for many of its sub-components: Jersey 1.11, Grizzly 1.9.46,Weld 1.1.4.Final, EclipseLink 2.3.2, Mojarra (JSF) 2.1.6, Metro 2.2, OSGi Core 4.3.0, JavaDB 10.8.1.2, OpenMQ 4.5.2 and more. It also now offers support for JDK 7 as well as for AIX. Full documentation for this release is available from this page.
GlassFish Server 3.1.2 is the fastest open source application server offering advanced features such as application versioning, application-scoped resources, and great development tool support from NetBeans 7.1.1, Eclipse and other popular IDEs.
After installing and using GlassFish 3.1.2, let us know what you think and, of course, feel free to get involved!
