In this section, we're going to take a look at how you can traverse REST resources using hypermedia (with links and URIs). We'll see how to use JSON-P to construct hypermedia enabled JSON structures. We'll use the @Context and UriInfo objects to construct resource URIs programmatically. We will also have a look at how to set link headers with URIs on the HTTP response.

Navigate to our book resource. In here, we have the method to serve a specific book. First up, we'll obtain the book and then we can construct...
