Quarkus: Sending CRUD (POST,GET,UPDATE,DELETE) messages to a Quarkus REST Service from an HTML Page. Given the a simple REST Service in Quarkus for basic CRUD operations (Create, Read, Update, Delete) calling the Read operation is as simple as invoking a GET method from an HTML form. On the other hand, invoking Create, Update and Delete normally implies sending an ID and/or some Data to the service. HTML Forms allow basic GET and POST methods, but no UPDATE and DELETE are offered by them. To solve this situation JQuery AJAX calls are necessary. Let the following simple REST service be our target: package org . acme ; import javax . ws . rs . GET ; import javax . ws . rs . POST ; import javax . ws . rs . PUT ; import javax . ws . rs . Path ; import javax . ws . rs . Produces ; import javax . ws . rs . Consumes ; import javax . ws . rs . DELETE ; import javax . ws . rs . core . MediaType ; @ Path ( "/example/crud" ) public class CRUDResource { @ GET @ Produc

JAVA JPA WITH HIBERNATE AND H2 Tutorial Setting the environment: Download and install H2 Database http://www.h2database.com/html/download.html Create a connection to the database, in my case I am using Netbeans. Creation of a new Database Connection can be done from the Services Tab, Databases node: Have in mind that it is not possible to test the connection before the JDBC URL has been written into. Select the PUBLIC schema when asked. And put a name onto it, I decided to name it as "Hibernate 101 on H2" Download Hibernate http://sourceforge.net/projects/hibernate/files/hibernate3/ JPA with Hibernate: For the shake of portability and standarization we will be using JPA. Natively speaking, Hibernate relies onto a context configuration file -  hibernate.cfg -  and a single or many persistence configuration files  - hibernate.hbm.xml - .  On the other hand JPA configuration is based on just one file:  persistence.xml.  Netbeans offe
