What's the meaning of timeout of an asynchronous operation

Hi, I don't understand the meaning of timeout of an asynchronous operation. Servlet 3.0 says The time out applies to the AsyncContext once the container-initiated dispatch during which one of the ServletRequest.startAsync methods was called has returned to the container. But when is the

Re: What's the meaning of timeout of an asynchronous operation

Thanks. So the only way to avoid the invocation of AsyncListener.onTimeout is that we invoke AsyncContext.complete or AsyncContext.dispatch? 2013/5/24 Mark Thomas ma...@apache.org On 24/05/2013 09:05, jie tang wrote: Hi, I don't understand the meaning of timeout of an asynchronous

Re: What's the meaning of timeout of an asynchronous operation

So if I use AsyncContext.start to run a Runnable. When that Runnable does some work but not write to response, will AsyncListener.onTimeout be invoked? 2013/5/24 Mark Thomas ma...@apache.org On 24/05/2013 09:16, jie tang wrote: Thanks. So the only way to avoid the invocation of

Re: What's the meaning of timeout of an asynchronous operation

I changed a little in my code: final AtomicLong writeResponseTime= new AtomicLong(0); final long timeout = 3; final AsyncContext async = req.startAsync(); async.setTimeout(timeout); async.addListener(new AsyncListener(){ @Override
