             Summary: Allow to specify subprotocol when using camel-vertx-websocket component
                 Key: CAMEL-15716
                 URL: https://issues.apache.org/jira/browse/CAMEL-15716
             Project: Camel
          Issue Type: Improvement
          Components: camel-vertx
    Affects Versions: 3.5.0
            Reporter: ncasaux


Hello,

I would like to use the component *camel-vertx-websocket* to do some Stomp over Websocket with an existing Websocket server (ActiveMQ in my use case).

However, netty logs keep saying this:

 
{code:java}
Caused by:
io.netty.handler.codec.http.websocketx.WebSocketHandshakeException:
Invalid subprotocol. Actual: stomp. Expected one of: null
{code}
I would like to pass a value for the subprotocol (like v12.stomp), but I don't know if it's possible.

However, I can see in the netty class 

 
{code:java}
io.netty.handler.codec.http.websocketx.WebSocketClientHandshaker{code}
 

that there are constructors that can take a subprotocol as a parameter:

 
{code:java}
/**
 * Base constructor
 *
 * @param uri
 * URL for web socket communications. e.g "ws://myhost.com/mypath". Subsequent web socket frames will be
 * sent to this URL.
 * @param version
 * Version of web socket specification to use to connect to the server
 * @param subprotocol
 * Sub protocol request sent to the server.
 * @param customHeaders
 * Map of custom headers to add to the client request
 * @param maxFramePayloadLength
 * Maximum length of a frame's payload
 */
protected WebSocketClientHandshaker(URI uri, WebSocketVersion version, String subprotocol,
 HttpHeaders customHeaders, int maxFramePayloadLength) {
 this(uri, version, subprotocol, customHeaders, maxFramePayloadLength, DEFAULT_FORCE_CLOSE_TIMEOUT_MILLIS);
}{code}
 

That would be great if we could pass this subprotocol to netty, to do some Stomp over Websocket :)
