Creating a database login screen using Primefaces and Hibernate

In this tutorial I will be creating a simple JSF login screen based on a database table. The final result will be a login form in which the user enters his username/password and it will redirect him to the home page or will show him a message indicating an invalid username/password or if his status is inactive.

In order to complete this tutorial you will need to complete those two tutorials, note that you will need to create both projects in the same workspace.

• Setup a primefaces dynamic web project.
• Setup a Hibernate JPA project.

Additional steps that you will need to do are:

1. Copy all the jar files found inside D:\workspaces\hibernate_lib to your primefaces web-inf/lib directory.
2. Right click your dynamic web project and select deployment assembly, click on Add ->Project, click on next and then select JPAProject, click on finish, and then in your web deployment assembly screen click on OK.

After setting up our projects, we'll start by creating our business logic related classes and jsf pages.

1. I will start by creating an enum with all the statuses of a login attempt, the enum looks like the following:
   
2.  Then I will add a new Transient property to the BhUser class to hold the login status of the user
   
3. Next I will create a UserDao interface and a UserDaoImpl class with one function called login which will take in a username and password and will return a BhUser object which will hold the login status within
   
   UserDao.java
   
   UserDaoImpl.java
   
4. Create a request scoped managed bean called Login.java
   
5. Create two xhtml pages, one for the login form and the other for your homepage
   
   WebContent/common/login.xhtml
   
   WebContent/common/home.xhtml
   

And the final result should be as follows

Offcourse you will need to have at least a single record in bh_user table to be able to test the application
