Hibernate JSF integration

Hibernate JSF integration

                         Hello Friends,today i am going to demonstrate you how hibernate orm framework can be integrated with JavaServerFaces.well for sake of simplicity i am not using annotation based configuration.i am pasting my code as given below.i am going to use traditional Student class for demonstrating the concept :

ManagedBean

package org.managedbean;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.SessionScoped;
import org.dao.StudentDAO;


@ManagedBean(name="student")
@SessionScoped
public class StudentBean
{

        private int id;
        private String name;
        private String college;
        @ManagedProperty(value="#{studentDAO}")
        private StudentDAO dao;
       
       
        public StudentDAO getDao() {
            return dao;
        }
        public void setDao(StudentDAO dao) {
            this.dao = dao;
        }
        public StudentBean() {
            // TODO Auto-generated constructor stub
           
        }
        public StudentBean(int id,String name,String college)
        {
            this.id=id;
            this.name=name;
            this.college=college;
           
        }
       
        public int getId() {
            return id;
        }
        public void setId(int id) {
            this.id = id;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getCollege() {
            return college;
        }
        public void setCollege(String college) {
            this.college = college;
        }
       
        public void insert()
        {
            getDao().insert(this);

        }
       
}
 
DAO LAYER:
package org.managedbean;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.SessionScoped;
import org.dao.StudentDAO;

@ManagedBean(name="student")
@SessionScoped
public class StudentBean
{

        private int id;
        private String name;
        private String college;
        @ManagedProperty(value="#{studentDAO}")
        private StudentDAO dao;
      
      
        public StudentDAO getDao() {
            return dao;
        }
        public void setDao(StudentDAO dao) {
            this.dao = dao;
        }
        public StudentBean() {
            // TODO Auto-generated constructor stub
          
        }
        public StudentBean(int id,String name,String college)
        {
            this.id=id;
            this.name=name;
            this.college=college;
          
        }
      
        public int getId() {
            return id;
        }
        public void setId(int id) {
            this.id = id;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getCollege() {
            return college;
        }
        public void setCollege(String college) {
            this.college = college;
        }
      
        public void insert()
        {
            getDao().insert(this);

        }
     
}

Util class:( for creating session factory)
package org.util;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

@ManagedBean
@SessionScoped
public class HibernateUtil
{
   
    private static final SessionFactory sessionfactory=buildSessionFactory();

    public static SessionFactory buildSessionFactory()
    {   
       
        try {
            return new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }
    public static SessionFactory getSessionfactory() {
        return sessionfactory;
       
    }
  }

i hope you will get my point.for any query related to this topic ping me on pathak.nisarg@yahoo.com
thanks for reading  this post,in the next post i am going to demonstrate  how we can reverse engineer on hibernate ORM.
