That's all there is to it (for the full JSON grammar description, visit http://www.json.org/).

The second method included in this class is bookPlace, which will be used to invoke the corresponding bookSeat class of our EJB. This method, on the other hand, is bound to the following HTTP POST method:

@POST @Path("/{id}") public Response bookPlace(@PathParam("id") int id)

You might be thinking that this Path expression seems a bit weird, but all it does is map a URI parameter (included in the Path expression) to a method parameter. In short, the parameter that is included in the URL will be passed to the method in the ID variable.

The previous method also returns a JSON-formatted string that is encoded and decoded using Jackson (by default, it is possible to create your own message body providers!), a library that transforms POJOs to JSON (and vice versa).

Before we proceed, we need to extend our sample with a new resource account, which will allow us to check the cash status and optionally reset it:

package com.packtpub.wflydevelopment.chapter7.boundary; @Path("/account") @Produces(MediaType.APPLICATION_JSON) @RequestScoped public class AccountResource { @Inject private TheatreBooker theatreBooker; @GET public AccountDto getAccount() { return AccountDto .fromAccount(theatreBooker.getCurrentAccount()); } @POST public Response renew() { theatreBooker.createCustomer(); return Response .ok(AccountDto.fromAccount(theatreBooker.getCurrentAccount())) .build(); } }
