SynchBasicHttpParams and ImmutableHttpProcessor missing

[HockeyDave]

The NIO httpcomponents client tutorial (•Basic non-blocking HTTP client) uses 2 classes which are missing from 4.0.1 release.  so.... downloaded 4.1-SNAPSHOT.  Classes are still missing.  
Downloaded the two files (found them w/ a google search).  Added them to my project.

Now ImmutableHttpProcessor is okay, but SyncBasicHttpParams is not good because it extends the class BasicHttpParams which in both the 4.0.1 release and the 4.1-SNAPSHOT is a final class.

can we get this remedied as I would like to try out the NIO implementation to see if that helps the performance of my use case?

Thanks.

I changed the examples page to point at the 4.0.x branch

http://hc.apache.org/httpcomponents-core/examples.html

Ideally one should be using examples shipped with the official release package.

Please note that generally NIO tends to be _significantly_ slower in terms of
raw data throughput compared to the classic I/O unless the number of concurrent
connections exceeds 2500 or even 5000. So, set your expectations right.

Thanks Oleg.  Pertaining to your comment about using examples shipped with the product...  I don't know about most people, but we're a heavy maven shop here so I don't really download products any more.  We just edit our pom file and magically it all works.  :)

If we need tutorials, we generally come back and get them separately.  I do appreciate you guys moving to maven and realize that you're in a transition phase so no worrries.

Best.

Hi Oleg.

Still struggling a bit with the NIO example.  How would one get the Response Entity Output?

            HttpContext context = conn.getContext();
            BasicHttpRequest httpget = new BasicHttpRequest("GET", "/", HttpVersion.HTTP_1_1);
            RequestHandle handle = new RequestHandle(connMgr, conn);
           
            context.setAttribute("request", httpget);
            context.setAttribute("request-handle", handle);
           
            queue.add(handle);            
            conn.requestOutput();
// I assume something should go here to get and process the response data???????

Thanks.
Dave

Dave,

Make sure you have read this tutorial:

http://hc.apache.org/httpcomponents-core/tutorial/html/index.html

Especially this bit:

http://hc.apache.org/httpcomponents-core/tutorial/html/nio.html#d0e1686

Hope this helps

Oleg
