Perhaps you can use a CXF client api instead ?
try
MyObject object =
WebClient.create(address).accept("application/xml,application/json").get(MyObject.class)
cheers, Sergey
David or Sergey,
I guess back to my original question....except this should be a bit more
clear.
I'm using apache's httpclient in order to process POST and GET requests to
my REST service methods. These POST and GET requests are being executed
from a JSF managed bean in order to retrieve an object and then perform
operations on that object before displaying it in a xhtml page. While using
xml I'm able to return the HttpResponse from the service method and use the
HttpResponse.getBodyAsString() along with JAXB in order to convert the xml
string to an object.
For JSON, what would be the best way to return the JSON string and then
convert that to an object so that I can return that to the consumer of the
service method (JSF managed bean) in order for it to perform operations on
it?

Subject: Re: How to use CXF and JSON
That did work, but it required me to save the json string as a file.
When
opening it in notepad it has the correct object representation. How
can I
display the json string in the browser? Do I have to setup something
prior
to making the request to the service method? Currently, I'm just
executing
a GET request by pasting in a url in IE.
Then don't do that. :)
Use SoapUI, or some other tool that knows JAX-RS. It can even read the
WADL specification and generate the tests for you.
