Care about using the web for real? Wanna write java clients to consume hypermedia links?
Here is how to do it with Restfulie java implementation.

1. Getting started

Suppose you have an uri (entry point) that returns an xml representing an order you have made. The Xml have two hypermedia links to be consumed. If you wanna pay for the order, you have to make an POST request to the link returned or and DELETE request canceling it.

The xml would be as follow:

What we need to do is use Restfulie to make the request, informing the entry point.

  Response response = Restfulie.at("http://caelum.com.br/orders/1").accetp("application/xml").get();
  Order order = response.getResource();
  resource(order).getLink("payment").follow().post(new Card(444));
