I believe JAX-RS 2 comes with a client API.

Commonly used implementations like Jersey and RESTEasy also comes
with client API's.

But I think a lot of developers just use plain Apache HttpClient
and whatever JSON or XML library they need to handle the data.

REST services are not like WS-* SOAP services.

Excellent. I will look into Jersey and RESTEasy as well. I have been using Apache HttpClient which works well I am just curious if there are additional API's used that provide additional features specific for REST.

There are so little you need to do RESTful style. HTTP, 4 methods,
headers, URL and body.

The data handling depends a lot on whether you use XML or JSON or CSV or
whatever format.

The response payload is even simpler than XML, JSON, CSV. Basically just returns a 0 or 1. With the HTTP Client there is sometime some additional whitespace parsing required. I believe the the minimal effort required to parse the response, the better.

https://authrequest.com/auth/auth?method=authenticate&organization=a&username=a&password=a
1 if failed and 0 if successful

I think this is in the true spirit of REST. If it can be done simple,
then no need to make it complex.

I have used CXF <http://cxf.apache.org/> in the past and can recommend it.

Please, before you look any further, check out Retrofit.

http://square.github.io/retrofit/

In short, an example to access the GitHub REST API:

public interface GitHubService {
  @GET("/users/{user}/repos")
  List<Repo> listRepos(@Path("user") String user);
}

RestAdapter restAdapter = new RestAdapter.Builder()
    .setEndpoint("https://api.github.com")
    .build();

GitHubService service = restAdapter.create(GitHubService.class);

List<Repo> repos = service.listRepos("octocat");

There, done. That's literally all you need.

Liebe Gruesse,
		Joerg
