No problem. One of the key problems with the success (or lack of success/popularity) or this project is that there are no good examples or templates. I will ensure to include many comprehensive standalone examples on the next release, including asynchronous request/response and websockets. This should make things much easier to understand and will enable users to get started with something that actually works.

Hey thanks a lot for your time.
It's much appreciated.

The current version works with that. This actually has more
to do with understanding threading, its really very easy to
get Simple working on such a scale. If you have past
experience with Servlets it will confuse you. Think of a
Response as a pointer to logic that can create and dispatch
a response.
For example
public class X implements Container {
private Set<Response> responses;
public Set<Response getResponses(){
return responses;
}
public void handle(Request request, Response response) {
responses.add(response);
}
}
Tell me why 200,000 responses can not be added to the
responses set?? Also tell me why 1 thread cant call
X.getResponses and perform some arbitrary logic on it? Then
call Response.close() and send the response to the client at
any arbitrary time?

Do you mean you need
WebSockets to handle 200,000 long polling requests with 8
threads? Does the current version of Simple not do that?
I'm not sure I'm following.

Hi Niall,
can you point me to some code that you might use for
such
long polling requests? Perhaps I'm missing
something,
and doing something in my code I shouldn't be.

I see that
there are exactly 8 servicing threads for requests by
default, in the pool. If I don't use an Executor,
and
I
get 8 requests that are long-running, or blocking,
then
any
other requests that come in must wait to be
serviced.

dont use an Executer, put the Request and Response in
a

asynchronous already...

Thanks
everyone for your responses, but perhaps I
wasn't
very
clear in my original message. I am simply trying to
implement a Container that does not create a new
thread
for
every request that requires an asynchronous
response.
In
the
Asynchronous services example I quoted in the
original
post,
a java.util.concurrent.Executor is used, and that
does
create a new thread for each request. I can't
see
an
obvious way to use a single separate thread and NIO
in
this
case.

That would be cool :)
Simple is integrated into milton.io
(webdav server framework) and while
most people use milton with servlets there are
always
some
using the
simple integration, particularly for embedded
webdav
servers.
And push notifications are coming to webdav where
websockets
will be the
main transport mechanism.
