Ok now it works, but here's the thing:
I switched to unwrapped mode. This time it's throwing me this:
INFO: URIParameterInterceptor handle message on path [/employees/33] with
content-type [null]
2007-08-17 08:46:25 org.apache.cxf.phase.PhaseInterceptorChain doIntercept
INFO: Interceptor has thrown exception, unwinding now
org.apache.cxf.interceptor.Fault: You can not map a URI parameter to a simple
type when in unwrapped mode!

... (more)
I changed back my service to wrapped mode (just doing what the stack trace told
me!). And then I had the idea to change my method argument to Long (the
wrapper type). It works ...
What is it with primitive types? Is there a problem using them against a REST
service?
Thanx a lot guys!

I think you also need to associate some meta-data with the id parameter in your
method signature since Java doesn't maintain any information about parameter
names. You can do this with the @WebParam annotation, e.g.
@Get
@HttpResource(location="/employees/{id}")
Employee getEmployee(@WebParam(name="id") long id);
I think you also need to annotate your implementation class, not just the
interface.

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.

Hi guys,
I am in the process of validating using web services in
conjonction with an AJAX layer on the front-side. The architecture of this
might look like:
- using CXF to expose REST services
- these services will throw out some JSON (via Jettison)
- the client side will use YUI to access the service layer
I have 2 questions for you all:
1) Has anyone ever tried that (AJAX -> WS) ? I thought it
might decouples a little more the GUI from the back-end.
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
2) Are the annotations used in CXF to build a RESTful WS, in
sync with what is going on in the JCP regarding JAX-RS (JSR 311 I think) ?
AFAIK JSR 311 will be implemented in CXF, and it is a relatively high
priority, but it is not there yet.
HTH,
Glen
