WebSockets & Java-WebSocket Library not working

[noblemaster]

Let me just say that SimpleFramework is fantastic :)

In any case, I am having some troubles getting WebSockets to work correctly (using 6.0.1). Although I am able to connect to SimpleFramework's WebSocket communication sometimes fails (succeeds about 30% of the time - JUnit). I am connecting with the Java WebSocket library (https://github.com/TooTallNate/Java-WebSocket). I tried with different protocols to no avail.

It's little bit difficult to find documentation on SimpleFramework's WebSocket, so I am not so sure if I am setting everything up correctly? I was following the spring.xml here (I am doing everything in code): https://github.com/ngallagher/simpleframework/blob/master/simple-demo/simple-demo-chat/etc/spring.xml

Questions:

1. What protocols are you supporting? All?
2. Is there any more documentation on how to set up things in code.
3. Do you have a Java websocket (not JavaScript) library you recommend with SimpleFramework?
4. Edit: also it appears you are only using 2 threads for the chat demo. Is that correct? For about 1000 connections how many threads do you recommend?

Hi,

FYI there is only one protocol, it is the draft standard version 13. In production environments where users have a modern/recent browser this is the only version you will see. Take a look at https://tools.ietf.org/html/rfc6455, I have developed it verbatim from this document alone.

If you think framework does not work, I would need a test case written in Java that can prove your hypothesis. Alternatively, I think perhaps it is best to speak to the developer of the Java WebSocket library, it is much more likely there is a bug here.

Thanks, Niall

Hi,

I confirm it is working like a charm ! You can inspire form the webserver I wrote on top of the lib:
