Advantages and Disadvantages
Apache HttpClient is a more complete solution and is better designed than
java.net.HttpURLConnection . Although you have to download it separately from the
JDK, I highly recommend you take a look at it. It has none of the disadvantages of Ht-
tpURLConnection , except that it is not JAX-RS-aware. Many JAX-RS implementations, in-
cluding RESTEasy, allow you to use Apache HttpClient as the underlying HTTP client en-
gine, so you can get the best of both worlds.
RESTEasy Client Proxies
The RESTEasy Client Proxy Framework is a different way of writing RESTful Java clients.
The idea of the framework is to reuse the JAX-RS annotations on the client side. When you
