Christoph Läubrich created WICKET-5033:
------------------------------------------
Summary: Websockets fail
Key: WICKET-5033
URL: https://issues.apache.org/jira/browse/WICKET-5033
Project: Wicket
Issue Type: Bug
Components: wicket-atmosphere
Affects Versions: 6.5.0
Reporter: Christoph Läubrich
Assignee: Emond Papegaaij
I played around with the AtmosphereExample, and got it already working. I just
noticed, that WebSockets requests are marked as "501 Not supported" even that
I'm running on a Jetty 8.
So I added
{code}org.atmosphere.cpr.asyncSupport=org.atmosphere.container.JettyAsyncSupportWithWebSocket{code}
to the init parameter, now the browser is able to open a Websocket connection
{code}[TRACE][qtp29683960-23 ] Destroyed request AtmosphereRequest{
contextPath= servletPath=/atmosphere pathInfo=/home requestURI=/atmosphere/home
requestURL=http://localhost:9999/atmosphere/home destroyable=false} and
response AtmosphereResponse{cookies=[], headers={}, asyncIOWriter=null,
status=200, statusMessage='OK', charSet='UTF-8', contentLength=-1,
contentType='text/html', isCommited=false, locale=null, headerHandled=false,
atmosphereRequest=null, writeStatusAndHeader=true,
delegateToNativeResponse=true, destroyable=true, response=HTTP/1.1 101

It seems for any reason Wicket lost a reference to the page...
