Consuming our REST service
Connecting to a RESTful web service takes no more work than directly connecting to the
service through an HTTP connection. For this reason, you can use plenty of APIs to ac-
cess your REST services, such as the JDK
URLConnection
class or Jakarta Commons
HttpClient API, since we have a standardized client available in JAX-RS.
If you want to retrieve the list of
Seats
from your REST service, your code should look
like this:
Client restclient = ClientBuilder.newClient();
WebTarget seatResource = restclient.target(APPLICATION_URL
+ "seat");
Collection<SeatDto> seats = seatResource.request().get(new
GenericType<Collection<SeatDto>>() {});
The previous code will simply perform a
GET
action to the REST service that is deployed
as part of the
ticket-agency-ws
web application. RESTEasy (using Jackson) will
transform the JSON objects.
The following standalone sample will get the data from the account and seat resources and
attempt to book all of the available seats:
public class RestServiceTestApplication {
private static final String APPLICATION_URL =
"http://localhost:8080/ticket-agency-ws/rest/";
