Ci sono così molti tutorial su questo se google "REST CRUD netbeans "esempio http://www.madebyjohann.com/index.php/college/learn-how/57-crud-in-a-restful-api-with-netbeans –
@ bearer bear Ho visitato così tanti siti che hanno progettato Programma Helloword che utilizza RESTful Webservice o che mostrava codice base, cioè generato da IDE ma non operazione CRUD. –
@ring bearer Ho seguito questo link http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/RESTfulWebServices/RESTfulWebservices.htm#t2 che descrive la connessione al database di esempio e il codice di generazione automatica dall'opzione RESTful Webservice dal database da Netbeans –
