In this tutorial, we will try to write a small hello world program using Hibernate, MySQL and Maven. We will create a Java project using Maven and will then try to add Hibernate on it.Following are the tools and technologies used in this project.Java JDK 5 or above Eclipse IDE 3.2 or above Maven 3.0 or above Hibernate 3.0 or above MySQL 5.0 or above1.

Hibernate was started in 2001 by Gavin King as an alternative to using EJB2-style entity beans. Its mission back then was to simply offer better persistence capabilities than offered by EJB2 by simplifying the complexities and allowing for missing features.Early in 2003, the Hibernate development team began Hibernate2 releases which offered many significant improvements over the first release.JBoss, Inc. (now part of Red Hat) later ...

Convention over configuration has became a buzz word these days. It is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. More and more web frameworks are using this approach and making web development simple. Ruby on rails, DJango, Grails, CakePHP, ...

Working with BLOB / CLOB data types in database is sometime a trivial task. I found particularly when working with Hibernate 3 to store and retrieve BLOB objects we need certain things to be taken care of. Let us see a tutorial where we will using Spring 3 MVC and Hibernate 3 to store and retrieve ...

Let us make a complete end-to-end application using Spring 3.0 MVC as front end technology and Hibernate as backend ORM technology. For this application we will also use Maven for build and dependency management and MySQL as database to persist the data.The application will be a simple Contact Manager app which will allow user to add new contacts. The list of contacts will be ...

While using Maven as build tool in our project, I found it very difficult to create a Dynamic Web Project which supports Maven dependencies and can execute in Eclipse! I have seen lot of people using Maven just as build tool and for local setup uses jar files in some /lib directory. I wanted to remove this dependencies on local /lib for jar files ...
