Cometd point to point

I am very new to cometd in jav开发者_如何转开发a.

I am interested more about cometd in java but when i googled it i barely find one link which is the cometd link and which is not clear in documentation.

Can some one post an example or a link which has a working example of publish subscribe and point to point?

Have you tried the RESTful Web Services and Comet article?

It has screenshots, step-by-step instructions, etc. The Glassfish Developer's Guide also has a nice article, with a downloadable WAR.
