Hi Eric
First of all, I must confess that im pretty new to all this webservice
stuff. I found a blog about restful web services that describes howto
interact with them:
http://blog.jonudell.net/2007/05/24/restful-web-services/
But you want a kind of client interface for that aswell?

Sergey,
I must admit my question was badly asked. Actually I am wondering how
I could use restful web-services if clients only get an XML
representation of the Object they request ?
I am not using SOAP, nor any WSDL description.
I expected to be able to get a kind of "stub" object on client side
(may be thanks to a sort of "unmarshalling" of this XML I get from the
server)
The CXF Jaxrs demo piece of code I have shown in my previous mail only
shows how to display an XML representation of Customer with Id 123
which is fine. But in my case, I would like to manipulate an actual
Customer stub instance, so that I can call methods on it and do
interesting things with what the server has sent to me.
I might be confused because so far I was using Hessian
(http://hessian.caucho.com/) where their binary protocol allow a web
service client to get an actual instance of the object they request.
I might be totally wrong about Restful web services, and I realize
that it may totally absurd to have the same behaviour with REST as
what I had with Hessian.
My question is more general :
How do Clients of Restful webservices get a concrete use of the XML
content they receive from the server ?
(I guess people just don't print out this XML on console :) but I
suppose they have to parse it/ unmarshall it in some way ?)
PS :I don't know about WADL , so please excuse my ignorance.
Thanks for helping anyway ;)
Eric

Hi
I'm wondering, are you actually asking for a code generation be done on a
client side with the help of a description language like WSDL 2.0 or WADL ?

Subject: JAXB Unmarshalling
I am going on playing with the restful_jaxrs sample demo
In the Client.java there are these lines
...
URL url = new URL("http://localhost:9000/customerservice/customers/123";);
InputStream in = url.openStream();
System.out.println(getStringFromInputStream(in));
....
What if I did not want to display the XML content (ie the XML
representation of customer whose Id is 123)
But rather I would like to get the actual instance of Customer with id is 123
Is there some Unmarshalling method to do that , something like
...
URL url = new URL("http://localhost:9000/customerservice/customers/123";);
InputStream in = url.openStream();
// Hypothetic code
Customer customer = (Customer) getObjectFromInputStream(in);
...
How would I implement this
Object getObjectFromInputStream(InputStream in)
method ?
I guess I would have to get a JaxbContext before I can get an Unmarshaller ?
Thanks for your help
Eric
