1. What exactly version of Tomcat you are using? https://wiki.apache.org/tomcat/FAQ/Linux_Unix#Q5 2. Does you copy of Tomcat has the following libraries in its lib directory? tomcat-websocket.jar websocket-api.jar 3. Loading of what class fails? Your class, or some of its dependencies? What is stacktrace when class loading fails? > I have been through the examples web.xml and cannot find any configuration > for websockets > at all except the listener definition for the old school version of web > sockets. (I'm > assuming this predated JSR-356.) All websockets in Tomcat 8 are JSR-356. ("Old-school" were in Tomcat 7, where both them and JSR-356 are available now).
