If you are in debugger, you can go to "threads" view and there should
be a way to copy a thread's stacktrace in its context menu.

I don’t think this is really Tomcat specific. Maybe start with a JSR-356
tutorial and see if that helps to answer your questions.
http://docs.oracle.com/javaee/7/tutorial/doc/websocket.htm
I also have some examples on Github, if you’re looking for more WebSockets
examples.

I appreciate the help, but I've been through the tutorials. I've been
debugging the code for tomcat 8.05 and this looks like a defect. It finds my
class in ContextConfig.checkHandlesTypes and then passes it to
Introspection.loadClass(), but the class load fails and so the class isn't
added to the list of endpoints. This is the exact thing that happens when I
pull the EchoAnnotation endpoint out of the examples webapp and try it
independently. Can I get someone to verify, please?

All websockets in Tomcat 8 are JSR-356. ("Old-school" were in Tomcat
7, where both them and JSR-356 are available now).
