Hi.
Sorry to jump in, and to top-post, and maybe make an irreverential comment :
But maybe the solution consists simply in renaming that filter, so that it does not give
the mistaken impression that the WebSocket protocol is necessarily being used ?

Hi Mark,

But even I have seen this in few of my exception traces though I never use
websockets.Some where down the line when exception is thrown wsfilter shows
up in traces.I am guessing it should be some kind of exception filter so it
bubbles up for exception types irrespective of protocol.
Let me check my old stack traces and post few snippets of it,but they were
valid exception in my case just that I never had websockets in my app.

We have a Jersey application running on Tomcat 7.0.62. In production,
99.9% of our web service calls run quickly (e.g., 100ms), but there are
about half a dozen web service calls per hour that take an extraordinary
amount of time to complete: 30-120 seconds (not ms).
We do not use WebSockets in our application. However, our profiling tool
clearly shows that Tomcat is invoking the WebSocket protocol on the
slow-running web service calls. In the stack trace below, see this line:
org.apache.tomcat.websocket.server.WsFilter.doFilter (WsFilter.java:46)
That shows nothing of the sort. I suggest you take a look at the code in
question before jumping to invalid conclusions.

How can we track down what is causing Tomcat to use the WebSocket
protocol, given that our application code does not make any references
to WebSocket annotations, etc.? Or is there a configuration option we
can use to cause Tomcat to not use WebSockets?
Thanks much.
