java - servlet 3.0 async-supported with jersey -

i'm trying understand under circumstances async-supported tag needed in web.xml async servlet processing jersey. if i'm doing async work, typically set in there. illustrate, have setup simple sevice

@get @produces(mediatype.application_json) public void myservice(@suspended asyncresponse response) { new thread(new runnable() { @override public void run() { response.resume(someresponseobject); } }).start(); }

in case, if don't set async-supported in web.xml, works fine.

is not working asynchronously think or there specific operations need before enabling async-supported required?

the async-supported alternative in web.xml or equivalent servlet annotation @webservlet(... asyncsupported=true) used indicate on servlet level potential long running background work carried out should handled in separate thread 1 handling request. thread handling request not blocked background work, doget() or dopost() method returns , thread can used handle request. task set in queue , handled thread threadpool initiated on application startup.

this has nil bailiwick of jersey asyncresponse handled bailiwick of jersey implementation. bailiwick of jersey rest service not servlet.
