Hum....
I hate people doing that, but I don't think we can do anything for
stopping them publishing such things. Neil is far from professional
pushing such junk emails....I will not waste my time and reply.

Subject: [Jersey] Jersey HTTP Container Contribution

Hi,
I would like to make a contribution to Jersey. I develop a light weight
high performance HTTP container called Simple
(
http://www.simpleframework.org). I have implemented a container and a
factory similar to the container Jersey has provided for Grizzly.
Simple has been hosted on Maven for about a year now and so would fit in
to the Maven build system provided for Jersey. The initial Jersey
container implementation is hosted on my sourceforge.net subversion
repository.
https://simpleweb.svn.sourceforge.net/svnroot/simpleweb/branches/4.1.2/security/src/jersey/
Simple is already integrated with the Restlet JAX-RS project
(
http://www.restlet.org) and has the following features, which I believe
would make it a useful contribution to Jersey.
1) Currently benchamarks at about twice as fast as Grizzly, Jetty, and
AsyncWeb

2) Supports the full set of HTTP capabilities, including integrated
multipart uploads, 100 continue, cookies, sessions, HTTP/1.0, HTTP/1.1,
HTTPS
3) Build around NIO so has very low latencies

http://www.simpleframework.org/performance/grizzly/run2/LatencyApacheBench.png
I plan to provide a full suite of tests for the container, similar to
the Grizzly container tests. Also ill add support for HTTPS.
Is there any specific criteria that needs to be satisfied before a
contribution is made?
Thanks,
Niall
