Yes, problem I mentioned in my first post was caused by no async support in web.xml. I added this line: <async-supported>true</async-supported> And everything worked well, almost... Now ContinuationProvider.getContinuation() return null after resuming the request (not always, but in ~95% of cases). Of course - I can store Continuation objects in some HashMap, and then everything seems to be ok at the first glance, but it's not the best solution, i think. No more information in logs, except those about NullPointerException.
That is of course not good. It's impossible for us to provide some feedback though without seeing some info or test project. Can you please temporarily try to downgrade to Tomcat 6 and see if that makes a diff ? It could be that the Servlet3 continuations are not very well 'wrapped' in CXF for ex, so if you could experiment with Tomcat 6 then it may help narrowing the problem
