Thanks Stuart. I need to avoid annotations since this will be configured
dynamically. I was wrong about the version, right now i'm on 2.0.9.Final.
I'm trying to create a websocket proxy. I was able to get the
ReceiveListener registered in Undertow and create a WebSocketClient. I'm
trying to pipe the data from the client through Undertow to the server,
starting with a Text message:
@Override
protected void onText(WebSocketChannel webSocketChannel,
StreamSourceFrameChannel messageChannel)
throws IOException {
PooledByteBuffer b = pool.allocate();
ByteBuffer buffer = b.getBuffer();
while (messageChannel.read(buffer) > 0) {
WebSockets.sendText(buffer, wsClient, null);
}
b.close();
}
The message sent to the downstream websocket server isn't right though (and
the server rejects it). The frame from wireshark just shows a buffer of
"\000\000...". I think I'm close but I don't see an example of how to
do
this. Any suggestions or pointers would be greatly appreciated.
Thanks

The easiest way would probably be to use the JSR-356 API. You
basically
just make an @ServerEndpoint that connects to the remote endpoint, and then
passes messages back and forth. The JSRWebSocketServer gives and example of
how to setup the server endpoint.
