So here's what I'm getting (my source code is attached) ...


__Telnet__

dador-iMac:~ dador$ telnet 10.0.1.14 8080

15:22:56,825 INFO  [stdout] (default I/O-3) now do something



So the queue is getting the data as it's being piped in (the blanks in the queued data are telnet line feeds). But I have to send a signal to the servlet that all of the data has been sent (I simply close the telnet connection). Then the listener's onAllDataRead() method gets called.

So maybe this is a configuration issue. By the way, it made a difference for me in the telnet session when I specified the Connection as "upgrade" versus "Upgrade".

Just a suggestion, but you may also want to take a look at the non-blocking I/O if you input stream is a long one.

Good luck,

--Jim.

Hi,

I dare to say that my code is correct ;) The problem is that it is NEVER called - this condition (even if it's wrong, however it's not) is never checked. When I remove this line:

out.setWriteListener(new EchoWriteListener(queue, out));

it seems to work. However, I have no writer, so it should be rather called SwallowListener... It's not my goal.

Maybe I should initialize WriteListener from the ReadListener after the first read? Or maybe, when I want to send back the response I should do this directly from the read listener? e.g. https://java.net/projects/tyrus/sources/source-code-repository/content/trunk/containers/servlet/src/main/java/org/glassfish/tyrus/servlet/TyrusHttpUpgradeHandler.java

Thanks,
Przemyslaw

At a first glance, I'd say your while{} block never returns. Is ServletInputStream.isFinished() what you've been looking for, instead of isReady()
