Basically we are using Undertow as shown in the ChatServer example
(https://github.com/undertow-io/undertow/blob/master/examples/src/main/jav...)
i.e. no JSR-356 API. With the small difference that we are sending binary data and we set
a buffer size using the Undertow builder. As Websocket client we are using the
AsyncHttpClient (https://github.com/AsyncHttpClient/async-http-client) which then fails
receiving messages larger than the set buffer size with an exception saying "Max
frame length has been exceeded.". Example code here:

How are you using websockets?
If you are using the JSR-356 API and deploying using WebSocketDeploymentInfo you need to
change the buffer size for outgoing connections in the setBuffers() call:
new WebSocketDeploymentInfo()
.setBuffers(new DefaultByteBufferPool(true, 1024))
Otherwise the buffer size from the Undertow builder should be used. Can you provide an
example of that you are doing?

Hi Stuart,
that's what I'm trying to do, sending large messages that consist of
multiple frames.
By buffer size do you mean this option:
Undertow.builder().setBufferSize(1024)....?
Because this doesn't work for me, the message (larger than 1024 bytes)
is always transferred in one frame.
Maybe you can provide an example how to do this correctly?
Thanks, Dominik

They the maximum size is determined by the buffer size (although this
refers to individual frames, you can still send larger messages using
continuation frames).
