JSF Hibernate Integration


JSF integration with Hibernate is a piece of cake. The JSF baking/managed beans are POJO's so it is possibe to direcly map the baking beans properties on the data base using hibernate maping.

Code of: hinernate.cnf

Hibernate Mapping File : SignUp.hbm

<!-- <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net /hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="signup.SignUp" optimistic-lock="version" polymorphism="implicit" select-before-update="false" table="SIGNUP"> <id column="UID" name="uid"> <generator class="increment"/> </id> <property column="FIRST_NAME" name="firstName"/> <property column="MIDDLE_NAME" name="middleName"/> <property column="LAST_NAME" name="lastName"/> <property column="USER_NAME" name="userName"/> <property column="USER_PASSWORD" name="password"/> <property column="PRESENT_ADDRESS" name="presentAddress"/> <property column="PERMANENT_ADDRESS" name="permanentAddress"/> <property column="CONTACT_NUMBER" name="contactNumber"/> </class> </hibernate-mapping> -->

Persistance POJO class: SignUp.java

Note : SignUp.java is also used as baking bean for SignUp.jsp view .

The JSF and Hibernate Integration is don in Baking bean's method processSubmit() through SignUpBOimpl Object .

Following is the code for SignUp.java

package signup; /** * * @author Murali */ import bo.SignUpBOimpl; import bo.iSignUpBO; import java.io.Serializable; /** * * @author Murali */ public class SignUp implements Serializable{ private int uid; private String firstName; private String middleName; private String lastName; private String userName; private String password; private String retypedPassword; private String email; private String presentAddress; private String permanentAddress; private String contactNumber; private String loginLink = "/JSF_HibernateIntegration01/faces/LoginForm.jsp"; private String loginLinkText = "Click here to Login"; private String message = ""; ///////// Action Listener////// public String processSubmit() { iSignUpBO signUpBOObject = new SignUpBOimpl(); if (password.equals(retypedPassword)) { signUpBOObject.userSignUp(this); message=""; return "submit"; }else{ message = "Passwords not are matched."; return ""; } } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } public String getLoginLink() { return loginLink; } public void setLoginLink(String loginLink) { this.loginLink = loginLink; } public String getLoginLinkText() { return loginLinkText; } public void setLoginLinkText(String loginLinkText) { this.loginLinkText = loginLinkText; } public void processSignUp() { } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getRetypedPassword() { return retypedPassword; } public void setRetypedPassword(String retypedPassword) { this.retypedPassword = retypedPassword; } public int getUid() { return uid; } public void setUid(int uid) { this.uid = uid; } /** * Get the value of contactNumber * * @return the value of contactNumber */ public String getContactNumber() { return contactNumber; } /** * Set the value of contactNumber * * @param contactNumber new value of contactNumber */ public void setContactNumber(String contactNumber) { this.contactNumber = contactNumber; } /** * Get the value of permanentAddress * * @return the value of permanentAddress */ public String getPermanentAddress() { return permanentAddress; } /** * Set the value of permanentAddress * * @param permanentAddress new value of permanentAddress */ public void setPermanentAddress(String permanentAddress) { this.permanentAddress = permanentAddress; } /** * Get the value of presentAddress * * @return the value of presentAddress */ public String getPresentAddress() { return presentAddress; } /** * Set the value of presentAddress * * @param presentAddress new value of presentAddress */ public void setPresentAddress(String presentAddress) { this.presentAddress = presentAddress; } /** * Get the value of password * * @return the value of password */ public String getPassword() { return password; } /** * Set the value of password * * @param password new value of password */ public void setPassword(String password) { this.password = password; } /** * Get the value of userName * * @return the value of userName */ public String getUserName() { return userName; } /** * Set the value of userName * * @param userName new value of userName */ public void setUserName(String userName) { this.userName = userName; } /** * Get the value of lastName * * @return the value of lastName */ public String getLastName() { return lastName; } /** * Set the value of lastName * * @param lastName new value of lastName */ public void setLastName(String lastName) { this.lastName = lastName; } /** * Get the value of middleName * * @return the value of middleName */ public String getMiddleName() { return middleName; } /** * Set the value of middleName * * @param middleName new value of middleName */ public void setMiddleName(String middleName) { this.middleName = middleName; } /** * Get the value of firstName * * @return the value of firstName */ public String getFirstName() { return firstName; } /** * Set the value of firstName * * @param firstName new value of firstName */ public void setFirstName(String firstName) { this.firstName = firstName; } }

Source Code for Untility Class: HibernateUtil.java

package com.myapp.struts; import org.hibernate.cfg.Configuration; import org.hibernate.SessionFactory; /** * Hibernate Utility class with a convenient method to get * Session Factory object. * * @author Murali */ public class HibernateUtil { private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from standard // (hibernate.cfg.xml) config file. sessionFactory = new Configuration().configure() .buildSessionFactory(); } catch (Throwable ex) { // Log the exception. System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } }

Persistance logic is seperated through DAO pattern .Following is the code for login & SignUp DAO's

Code for LoginDAO.java

Code for SignUpDAO

Login Business Logic is seperated through BO pattern.Following is the code for Logic and SignUp BO's .Interfaces are used to provode the loose coupling

Code for iLoginBO interface

Code for LoginBOimpl this calss implements the iLoginBO interface

Code for iSignUpBO interface

Code for SignBOimpl
