Hi,
I'm trying to use wicketstuff-push in my project. I'm always getting a
ClassCastException in the wicketstuff-push sources, which I can't explain:
java.lang.ClassCastException:
org.mortbay.cometd.continuation.ContinuationBayeux cannot be cast to
org.cometd.Bayeux
at
org.wicketstuff.push.cometd.CometdService.initBayeux(CometdService.java:172)
at
org.wicketstuff.push.cometd.CometdService.getBayeux(CometdService.java:161)
at
org.wicketstuff.push.cometd.CometdService.publish(CometdService.java:155)
at org.xtoto.ui.comment.CommentPanel$3.onSubmit(CommentPanel.java:140)
My code is very similar to the example:
final ChannelEvent event = new ChannelEvent("chat");
event.addData("message", comment.getMessage());
getChannelService().publish(event); // -> Line 140 in CommentPanel
I'm using the trunk of wicketstuff. The org.wicketstuff.push code
compiled perfectly.
I tried different library versions - which didn't help.
Currently I'm using
cometd-api-1.1.1
cometd-client-6.1.22
cometd-server-6.1.22
jetty-6.1.22
wicket-1.4.7
When I change the code in push a little bit, from
_bayeux = (Bayeux) _application
.getServletContext()
.getAttribute(Bayeux.ATTRIBUTE); // -> line 172 in CometdService
to
ContinuationBayeux b = (ContinuationBayeux)_application
.getServletContext()
.getAttribute(Bayeux.ATTRIBUTE);
_bayeux = b;
I get a IncompatibleClassChangeError later in line:
serviceClient = _bayeux.newClient(BAYEUX_CLIENT_PREFIX);
Very strange...
Has anyone had this problem before? Any ideas?
Regards
Ingo
