Designing a domain model for a TODO list application

As I promised in my previous article this one will be about designing a domain model for a TODO list application. Then, We will implement this domain model in Hibernate, make Primefaces user interface, configure MySQL database and deploy this application on JBoss 7.1 AS. The first thing we need to do is to define requirements for our application. Then we will go through designing a database diagram and UML class diagram for application models. To create UML diagrams I am going to use ArgoUML open source modeling tool which runs on Java platform. In order to design a database diagram I am going to use data modeling functionality included in MySQL Workbench.

From Zero to PrimeFaces Hero on JBoss 7.1 with Hibernate, MySQL, Eclipse Indigo and JBoss Tools

From Zero to PrimeFaces Hero is a series of articles, in which I indented to explain how to create a full CRUD webapp in PrimeFaces, Hibernate, MySQL, Eclipse Indigo and JBoss Tools. I will describe the way of building a simple CRUD application, which will be deployed on JBoss 7.1. The full path of builiding an application will be described as follows:

• Configuring IDE. In this case, it will be Eclipse Indigo,


• Designing and implementing data model in Hibernate,


• Synchronizing MySQL scheme with Hibernate Entities,


• Building ManageBeans for business logic and integrating it with data model layer,


• Building JSF interfaces and integrating it with ManageBeans,


• Artifacts deployment on JBoss 7.1 Application Server.

After reading this series you will be able to build a full-featured CRUD JSF application backed by MySQL database with Hibernate mapping. Stay tuned for the next article on this topic.
