Problem with websocket on Jetty 9.4.12
Hi all
after the migration to karaf 4.2.3 my websocket stops to work.
I have the following error
Caused by: java.lang.ClassNotFoundException:

All works fine with previous version.
Have you some idea?

Hi JB
thank you very much.
The issue is how I was creating the servlet. I was not using the HttpServer.
Now it works fine :-)

Giuseppe

Hi,
Do you have the corresponding import in your bundle ?
Did you take a look on the websocket example:
https://github.com/apache/karaf/tree/master/examples/karaf-websocket-example
?
