JAX-WS RESTful Web Service - AJAX client
You have already seen quite a few examples of JAX-WS clients accessing RESTful clients. Marc's blog. I wrote a sample RESTful webservice using latest mustang JDK(b91).
The rest.zip contains sources and run.sh. Once you run run.sh, it shows a URL that can be used from browser.
I tested the example with some browsers like IE, Firefox. IE poses some problems like caching, and doesn't send a default Content-Type with XMLHttpRequest.send(). So I added some extra lines in the index.html to take care of them.
