Can you please try latest nightly?

http://dlc.sun.com.edgesuite.net/glassfish/4.0/nightly/glassfish-4.0-b82-03_26_2013.zip

and if it still does not work, can you provide more details about your setup? (os?)

Thanks,
Pavel

Dear Pavel,


I have tried your sample even I do not see much difference to my code. I
tested it on Glassfish 4b81, i.e. the same Glassfish that I had run my
stuff. This version is the latest Glassfish version currently available.
What I did is compiling and deploying the Webapp, opening in Chrome v25,
clicking "Connect" button and then "Send" button.

Here is the output from the server:
<click Connect> Someone connected...

And here from the client:
<click Connect> CONNECTED to
ws://localhost:8080/sample-simplelife/simplelife
<click Send> Error: InvalidStateError: DOM Exception 11


According to Chrome, the Websocket is still pending to be opened, i.e.
receive the response from the server. Yet, the readyState of the Websocket
is 1.

Unfortunately I cannot install a packet sniffer like Wireshark to see if the
server responds anything to the browser.

Hi Bjoern,

can you please try running Tyrus sample? For example this one:

http://java.net/projects/tyrus/sources/source-code-repository/show/trunk/sam
ples/simplelife?rev=549
(includes simple js client)

should do what you want. (you might need to use newer glassfish build, there
was new release of websocket-api in the meantime).

Also, you can use users@... mailing list.

Regards,
Pavel

Good evening,


I am trying html5 websocket technology with Glassfish. I use the
Glassfish 4 b81 with JSR-356 support built-in. Yet, I fail to actually
really open a websocket. In google Chrome, it says that the websocket
connection is pending. When I try to send something from the browser
to the server via the websocket, I will get invalidDOMException with
code 11. Sending something from the server to the client does not
result in any exception (or even log message) but message is never
received at the browser.


Here is my server-side code:

@ServerEndpoint(value="/ws") public class CWSHandler {
        @OnOpen public void open(Session S) {
                System.out.println("### NEW CONNECTION OPENED ###");
        }
        
        @OnMessage public void process(ByteBuffer Data, Session S) {
                System.out.println("### GOT MESSAGE ###");
        }
        
        @OnError public void error(Session S, Throwable Cause) {
                System.out.println("### HAVE ERROR ###");
                if (null != Cause) { Cause.printStackTrace(); }
        }
        
        @OnClose public void close(Session S, CloseReason Reason) {
                System.out.println("### CONNECTION CLOSED ### " +
Reason.getReasonPhrase());
        }
}


And here is the client code:

var commChannel = new WebSocket(wsURI); commChannel.onerror = function
(evt) { console.log("Error: " + evt); }; commChannel.onopen = function
(evt) {
        console.log("Connection opened: " + evt);
        try { commChannel.send("Hello world"); }
        catch (err) { console.log(err); }
};
commChannel.onclose = function (evt) { console.log("Connection closed:
" + evt); };
commChannel.onmessage = function (evt) { console.log("Received message
from websocket: " + evt); };



The output on the server is:

[2013-03-26T20:23:34.949+0100] [glassfish 4.0] [INFO] [] [] [tid:
_ThreadID=30 _ThreadName=Thread-3] [timeMillis: 1364325814949]
[levelValue: 800] [[
    ### NEW CONNECTION OPENED ###]]


The output on the client is:
Connection opened: [object Event]                       line 4
Error: InvalidStateError: DOM Exception 11              line 6



What am I missing?
