Websocket on tomcat 7.0.50 not working
I am trying to implement a websocket on tomcat 7.0.50 using annotated
endpoints as specified in Java Websocket API (1.0)- JSR 356. Following are
the brief steps how I have coded it 1) Write a websocket endpoint using
@ServerEndpoint annotation 2) implement @onOpen and @onMessage methods 3)
open a websocket using javascript on google chrome.
Please find code corresponding to above steps in order
1) STEP 1 & 2 - writing websocket server endpoint:
package com.jkweb.websocket;
import java.io.IOException;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.websocket.EndpointConfig;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.PathParam;
import javax.websocket.server.ServerEndpoint;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@ServerEndpoint(value="/websocket/fileuploadtracker")
@OnOpen public void open(Session session,EndpointConfig config) {
......}@OnMessagepublic void onMessage(Session session, String msg) {
try {
session.getBasicRemote().sendText(msg);
} catch (IOException e) {
logger.error(e.getMessage());
}}
public static void sendMessage(String uniqueTocken,String msg){
try {
Session wsSession = socketConnectionMap.get(uniqueTocken);
wsSession.getBasicRemote().sendText(msg);
} catch (IOException e) {
logger.error(e.getMessage());
}}
}
2) STEP 3 - opening websocket using javascript api in chrome:
wsurl = "ws://localhost:8080/jkweb/websocket/fileuploadtracker",
ws;
ws = new WebSocket(wsurl);
ws.onopen = function()
{
// Web Socket is connected, send data using send()
ws.send("Sending first Message");
alert("Message is sent...");
};
ws.onmessage = function (evt)
{
var received_msg = evt.data;
alert("Message is received...");
};
ws.onclose = function(evt)
{
// websocket is closed.
alert("Connection is closed..."+evt.code + ":"+evt.reason );
};
I am using following versions of softwares : 1) Tomcat - 7.0.50 2) Java -
1.7.45 3) Servlet - 3.0 4) Have included following Maven dependency 5)
Chrome - 32.0.1700.107m
<dependency>
<groupId>javax.websocket</groupId>
<artifactId>javax.websocket-api</artifactId>
<version>1.0</version>
<scope>provided</scope></dependency>
However I am getting following error and connection is closed with 1066
error code in chrome's console:
WebSocket connection to
'ws://localhost:8080/jkweb/websocket/fileuploadtracker' failed: Error
during WebSocket handshake: Unexpected response code: 404
Is there any configuration I am missing out on. I tried to search a lot but
couldn't find anything. Please I need this to be solved ASAP.
Thanks,
Shailesh

Hey guys,
I have solved it. Problem was very specific to my installation.
I had the websocket api .jar being installed in my app's WEB-INF/lib
directory as well.
Not sure why it was breaking it. can you put some light on the root cause
of this behaviour and why it doesn't work when you gave websocket-api.jar
in application's WEB-INF/lib along with tomcat's lib?
If possible you can answer the similar question I have posted on
stackoverflow.com as well.
Thanks,
Shailesh

Another Update:
I downloaded 8.0.3 as well and started it without eclipse and deployed the
app but still the same result. How to check if tomcat is creating the
server endpoints for my websocket?
I don't understand what I am doing wrong?
Guys,
need your help ASAP.
Thanks,
Shailesh.

Can you check the context root of the deployed application? Is it "jkweb"?

Re: Websocket on tomcat 7.0.50 not working

just an update :
this is what i get in tomcat access logs :
127.0.0.1 - - [18/Feb/2014:16:42:45 +0530] "GET
/jkweb/websocket/fileuploadtracker HTTP/1.1" 404 1017
is this correct ??

Also I using Struts 2. but my Struts2 servlet only handles urls with
pattern : *.action
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
Also I have configured Spring security but logs show that it is filtering
the request properly.

I have currently deployed it through Eclipse Juno. However I am *not * using
Eclipse's instance. My webapp gets deployed in my tomcat and not Eclipse's
one.
Please let me know any additional information you need. Or please let me
know how to go debugging it like checking if Websocket Server endpoints are
actully mounted to accept the connections or not and other diagnostics?
Thanks,
Shailesh.

I don't see anything immediately wrong.

How have you deployed your web application?
