Hibernate and Primefaces CRUD Using NetBeans 8.02 and MySQL Database Server

Introduction 

 
This simple application is a Create, Read, Update and Delete application operating on a ‘User’ table in ‘test’ database in MySQL Database Server. It is a Hibernate-Annotation based application.
 
Software Used
  1. JDK8u25
  2. Netbeans 8.02
  3. MySQL 5.*(or XAMPP)
  4. MySQL Connector 5.*
  5. Hibernate 4.3.** and Primefaces 5.0(Bundled with Netbeans)
Steps
  1. Install JDK8 or Jdk7 if not installed
  2. Install Netbeans and associated ApacheTomcat Server
  3. Install MySQL Database server or XAMPP(For easy management of MySQL ) .
After Installing Netbeans click the services tab on the left. Expand Database node. Expand Drivers node. Right click MySQL(Connector/Jdriver) then connect. Put test as the database, as shown below. Put password if you have given your password at the time of installation of MySQL database server. For XAMPP no password is required. Then test connection. If successful click finish button.
 
 
 
Create user table by running the below SQL in ‘test’ database.
  1. CREATE TABLE IF NOT EXISTS `user` (  
  2.     `id` int(10) unsigned NOT NULL auto_increment,  
  3.     `RecordNo` varchar(20) DEFAULT NULL,  
  4.     `Name` varchar(50) DEFAULT NULL,  
  5.     `Age` int(11) DEFAULT NULL,  
  6.     `Sex` varchar(20) DEFAULT NULL,  
  7.     `Dob` date DEFAULT NULL,  
  8.     `Remark` varchar(50) DEFAULT NULL PRIMARY KEY(`id`)  
  9. ) ENGINE = InnoDB AUTO_INCREMENT = 1 DEFAULT CHARSET = utf8;  
Insert these Records below by executing the below insert statement:
  1. INSERT INTO `user` (`id`, `RecordNo`, `Name`, `Age`, `Sex`, `Dob`, `Remark`) VALUES  
  2. (1, '1', 'Raichand', 48, 'Male', '2014-06-16', 'Good Person'),

  8. (10, '10', 'Jyoti Rath', 21, 'Male', '2016-01-26', 'good person'),  
  9. (11, '11', 'Sruti Rath', 21, 'Male', '2016-01-26', 'good person'),  
  10. (13, '13', 'Pradipta Prusty', 34, 'Male', '2016-01-18', 'good person'),  
  11. (14, '14', 'sunita misra', 21, 'Female', '2016-01-27', 'good lady'),  
  12. (15, '15', 'sibananda mitra', 32, 'Male', '2016-01-25', 'good person'),  
  13. (16, '16', 'smita rath', 23, 'Female', '2016-01-20', 'good lady'),  
  14. (17, '17', 'Smita satpathy', 21, 'Female', '2016-01-26', 'good lady'),  
  15. (18, '18', 'N.C Das', 32, 'Male', '2016-01-26', 'Good Person'),

Creating Project UserCRUD_Annotation
 
File->New Project->Categories->Choose JavaWeb->Choose WebApplication->Click Next->Give Project Name UserCRUD_Annotation->Click Next->Click Next->Choose Framework First Hibernate then Java Server Faces->Click Component Tab->Choose Primefaces->Click Finish.
 
 
 
Download mysql- connector-java-bin.jar and add to libraries folder by copying and pasting.
 
Project Structure
 
 
 
Creating Packages and Classes
 
Right click Source Package folder and create four packages: 
  1. com.controller.bean: This would contain JSF Managed Bean Class UsererBean.java.
  2. com.dao: This would contain DAO(Data Access Object) class UsererDao.java.
  3. com.model.pojo: This would contain entity(POJO) class User.java.POJO Stands for Plain Old Java. Objects
  4. com.util: This will contain HibernateUtil.java class.
Default package contains two files hibernate.cfg.xml and hibernate.reveng.xml file:
 
Following Files would be created using Netbeans:
  1. hibernate.cfg,xml File: Automatically generated.
  2. Reverse Engineering File: hibernate.reveng.xml
  3. Entity(POJO) File: User.java(POJO stands for Plain Old Java Objects)
  4. JSF Managed Bean File: UserBean.java
  5. DataAccessObject(DAO) File: UserDao.java
  6. HibernateUtil.java File
  7. Index.xhtml(Automatically generated): Adds new user and displays all users information
  8. Search.xhtml: Search a user then edit or delete it
  9. UserCrud.xhtml: It is an independent file to be run independently by selecting it in TOC and running it by Run(From Menu): Run File
  10. web.xml(Automatically generated)
Add mysql- connector-java-bin.jar to libraries folder by copy and paste if not done.
 
Copy and paste code of the file given below whose code is not generated
 
1. Hibernate.cfg.xml File
 
As XAMPP is used so there is no password in the file only username is given that is root in Hibernate.cfg.xml File.
 
Code
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

  17. </hibernate-configuration>  
2. Creating Reverse Engineering File->hibernate.reveng.xml
 
 
 
Right Click default package in the Source Package->new->choose Hibernate Reverse Engineering Wizard ->click next->choose customer table->Add ->click finish.
 
Code
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd">

  4.     <schema-selection match-catalog="test" />  
  5.     <table-filter match-name="user" />  
  6. </hibernate-reverse-engineering>  
3. Creating Hibernate Entity (pojo) File:-user.java
 
Important: To create this file MySQL database test most be connected through Netbeans.
 
Right click com.model package->new->Hibernate Mappling Files and pojos from database -> Do not select mapping file & select EJB3.0 Pattern -> Click Finish
