<div dir="ltr"><div dir="ltr">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:<div><br></div><div><div>@Override</div><div><span style="white-space:pre"> </span>protected void onText(WebSocketChannel webSocketChannel, StreamSourceFrameChannel messageChannel)</div><div><span style="white-space:pre"> </span>throws IOException {</div><div><span style="white-space:pre"> </span>PooledByteBuffer b = pool.allocate();</div><div><span style="white-space:pre"> </span>ByteBuffer buffer = b.getBuffer();</div><div><span style="white-space:pre"> </span>while (messageChannel.read(buffer) > 0) {</div><div><span style="white-space:pre"> </span>WebSockets.sendText(buffer, wsClient, null);</div><div><span style="white-space:pre"> </span>}</div><div><span style="white-space:pre"> </span></div><div><span style="white-space:pre"> </span>b.close();</div><div><span style="white-space:pre"> </span>}</div><div><br></div><div><br></div><div><div class="gmail-m_-9014391979265479174gmail_signature">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.</div><div class="gmail-m_-9014391979265479174gmail_signature"><br></div><div class="gmail-m_-9014391979265479174gmail_signature">Thanks</div><div class="gmail-m_-9014391979265479174gmail_signature"><br></div><div class="gmail-m_-9014391979265479174gmail_signature"><br></div><div dir="ltr" class="gmail-m_-9014391979265479174gmail_signature"><br></div><div dir="ltr" class="gmail-m_-9014391979265479174gmail_signature">Marc Boorshtein<br><br></div></div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Nov 29, 2018 at 5:07 PM Stuart Douglas <<a href="mailto:sdouglas@redhat.com" target="_blank">sdouglas@redhat.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr">The easiest way would probably be to use the JSR-356 API.
