Thanx for your answer Glen.

I tried to develop, based on one of the samples, a small REST web service.  It 
works.  But there is a small thing I can't understand: It's the parameter 
mapping in the REST uri.

I have a method in my service interface declared in a way that it expects an 
employee id:

@Get 
@HttpResource(location="/employees/{id}") 
Employee getEmployee(long id);

BTW, this doesn't work.  I can't understand why.  Maybe I don't get what CXF is 
doing with the ID in the uri.  It's throwing me this exception when I try to 
access the URL:

http://localhost:8080/cfx-web/services/employeeService/employees/33

Thanx for your time.

JS.

Chapter 10 in Mark Hansen's SOA book covers AJAX -> WS in general (if not 
precisely the way you wish to do this).  That sample chapter is available as a 
free download here:
http://www.theserverside.com/tt/articles/article.tss?l=AjaxJavaWebServices_Chapter

You may need some of the Chapter 9 code to understand Chapter 10--all source 
code is available at http://soabook.com

AFAIK JSR 311 will be implemented in CXF, and it is a relatively high priority, 
but it is not there yet.

HTH,
