Hi,

I am using stomp over sockjs in my spring application. I have two issues with it.

When I use chrome and send big messages and lot of it, I get

org.springframework.web.socket.sockjs.SockJsTransportFailureException: Failed to

I use tomcat 7.0.53. I suspect that some buffer size is small, so messages are broken...

Is there some way for configuring this

2. Every 10 minutes(if nothing happens) socket closes. Is there some way for disabling this timeout? Or is this done over heartbeats?

Regards,
Marko

You almost certainly want to create your own heartbeat system, besides helping to keep connections alive it will allow you to periodically check for broken connections that sockjs isn't aware of - giving you a more accurate list of connected users.

Get the clients to send in a heart beat every 20 seconds, update your server side array with the time on each beat, and get the server to check the array every 30 seconds for current time less 30 seconds = remove user & connection

The best way to keep connections alive however is to use HTTPS.
I seem to get disconnections every 2-3 minutes if my broadband is losing packets.

Using a heartbeat and auto client re-connection code will make these drops transparent, however you will need to buffer server and client side, report and send buffers on reconnection.

If you don't want to get in to buffering, I recommend a connection layer over sockjs to do it all for you called:

primus

Good luck
