Hi! It looks like you have a RequestCycle listener (an anonymous class inside your tw.com.slsinfo.WicketApplication class), which is throwing an exception in its “onEndRequest” implementation.
Since that is your own code, you need to have a look at line 108 in your WicketApplication and figure out why it is throwing an exception 🙂 Met vriendelijke groet, Kind regards, Bas Gooren Op 7 sep 2025, 18:04:30 schreef 黃魚鴞 <front...@gmail.com>: > Dear all > > One i add WebSocketBehavior on page, when i start the web server (Wildfly) > , it showed error message: > > 16:01:43,648 ERROR [stderr] (default task-1) [default task-1] ERROR > org.apache.wicket.request.cycle.RequestCycle - Exception occurred during > onEndRequest > > 16:01:43,648 ERROR [stderr] (default task-1) > java.lang.UnsupportedOperationException > > 16:01:43,648 ERROR [stderr] (default task-1) at > deployment.llm4class-web-0.0.1-SNAPSHOT.war//org.apache.wicket.protocol.ws.api.WebSocketResponse.setHeader(WebSocketResponse.java:185) > > 16:01:43,648 ERROR [stderr] (default task-1) at > deployment.llm4class-web-0.0.1-SNAPSHOT.war//tw.com.slsinfo.WicketApplication$1.onEndRequest(WicketApplication.java:108) > > How do I fix this? > > Shengche > > >
