My code is running fine...everything is o.k. But when i check my database .it reflects empty set...my code is written below


[java] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
[java] log4j:WARN Please initialize the log4j system properly.
[java] Inserting Record
[java] Done
[java] Hibernate: insert into CONTACT (FIRSTNAME, LASTNAME, EMAIL, ID) values (?, ?, ?, ?)
BUILD SUCCESSFUL

package hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;



public class FirstExample {

private Session session;

public static void main(String[] args) {
Session session = null;

try{
Configuration configuration = new Configuration();
configuration.setProperty("hibernate.connection.driver_class", com.mysql.jdbc.Driver.class.getName());
configuration.setProperty("hibernate.connection.url",("jdbc:mysql://localhost:3306/hibernatetutorial"));
configuration.setProperty("hibernate.connection.username", "root");
configuration.setProperty("hibernate.connection.password", "test");
configuration.setProperty("hibernate.connection.pool_size", "1");
configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
configuration.addClass(Contact.class);
session = configuration.buildSessionFactory().openSession();

//"C:\\svn\\workspace\\hibernateTutorial\\cfg\\hibernate.cfg.xml"
// This step will read hibernate.cfg.xml and prepare hibernate for use
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
session =sessionFactory.openSession();
//Create new instance of Contact and set values in it by reading them from form object
System.out.println("Inserting Record");
Contact c = new Contact();
c.setId(3);
c.setFirstName("Deepak");
c.setLastName("Kumar");
c.setEmail("deepak_38@yahoo.com");
session.persist(c);
System.out.println("Done");
}catch(Exception e){
e.printStackTrace();
System.out.println(e.getMessage());
}finally{
// Actual contact insertion will happen at this step
session.flush();
session.close();

}

}

}

I think you must commit the transaction before you close the session.

solution of the following error is ..
1. insert autocommit in configration xml file
2. use transaction on hibernateutil.java

Like this:

thanks i did
