Only one method is executed for a single request. So it is impossible to execute two methods (or more) in single request;
JAX-RS runtime decides which one method should be executed according to request header values sent to to the server.
JAX-RS runtime tries to match:
http method (GET,POST, ...) with proper annotation (@GET, @POST,...);
request path ('/api/something') with the proper @Path annotation;
http content-type header (link) with proper @Consumes annotation;
http accept header with propper @Produces annotation;
So (for example) @Produces annotation does not denote that annotated method produces something. It denotes that method will be executed when matching accept header will be contained in request.
