If you need to go that route, Example 6-02 of the JAX-RS book
examples[1] has a rather complex MessageBodyReader/Writer example. Note
this example had uncovered a bug that was quickly fixed in CXF 2.3.2
which should be released very shortly[2] -- however most other MBR/MBW
implementations will work in CXF 2.3.1.

3. I checked the example Glenn suggested, however that example does NOT use
"ResponseReader". The method "useSimpleProxy" in "RESTClient.java", creates
a
client proxy from which it retrieves a collection of person objects; it
never
deals with a "Response" object. Did I miss something in the example?
I apologize, the code I mentioned above will be in the *next* release of
the Talend examples, it actually uses brand new functionality put in by
Sergey in CXF 2.3.2. An example of ResponseReader (from the upcoming
Talend samples) is below:
public void useSimpleProxy() {
System.out.println("Using a simple JAX-RS proxy to get all the persons...");
ResponseReader reader = new ResponseReader();
reader.setEntityClass(PersonCollection.class);
String webAppAddress = "http://localhost:"; + port +
"/services/personservice";
PersonService proxy = JAXRSClientFactory.create(webAppAddress,
PersonService.class,
Collections.singletonList(reader));
// getPersons(a, b): a is zero-based start index, b is number of records
// to return (-1 for all)
Response resp = proxy.getPersons(0, -1);
if (resp.getStatus() == 200) {
PersonCollection personColl = (PersonCollection)resp.getEntity();
List<Person> persons = personColl.getList();
for (Iterator<Person> it = persons.iterator(); it.hasNext();) {
Person person = it.next();
System.out.println("ID " + person.getId() + " : " + person.getName() +
", age : "
+ person.getAge());
}
}
}
Again, though, this will unfortunately need to wait until CXF 2.3.2 is out.
HTH,

Thanks.

Subject: Re: How to convert response input stream to java object
ResponseReader is a custom MessageBodyReader<Response> handler which is
registered on the client side, it allows to do a safe type casting, such
as
Response response = webClient.get();
Book book = (Book)Response.getEntity();
It's possibe to write your own custom Response reader with any CXF
version
supporting the client api, but using the ResponseReader makes it
simpler...
Please check the demo Glen linked to.

I think ResponseReader, recently introduced in CXF 2.3.1, is your

If you go to the Talend Service Factory (CXF wrap) Examples[1], under
examples/jaxrs-advanced/client/..../RESTClient.java, method
useSimpleProxy()
has it.
