Abdu Zaki 8 Years Ago Thanks for this great demo. It worked fine. One thing is annoying though is it throws an error from time to time:Nov 17, 2015 1:09:01 PM org.apache.catalina.core.StandardWrapperValve invokeSEVERE: Servlet.service() for servlet [cometd] in context with path [/ems.map.portlet-portlet] threw exception [Servlet execution threw an exception] with root causejava.lang.NoClassDefFoundError: org/eclipse/jetty/server/AbstractHttpConnection at org.eclipse.jetty.websocket.WebSocketFactory.upgrade(WebSocketFactory.java:235).... ANY IDEA HOW TO FIX THIS? THanks Please sign in to reply. Reply as... Cancel
