Thanks.

hi,
my hibernate.cfg.xml is
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">;

<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernate</property>;
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.connection.pool_size">10</property>
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- Mapping files -->
<mapping resource="contact.hbm.xml"/>
</session-factory>
</hibernate-configuration>
my contact.hbm.xml is :
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">;
<hibernate-mapping>
<class name="roseindia.tutorial.hibernate.Contact" table="CONTACT">
<id name="id" type="long" column="ID" >
<generator class="assigned"/>
</id>

<property name="firstName">
<column name="FIRSTNAME" />
</property>
<property name="lastName">
<column name="LASTNAME"/>
</property>
<property name="email">
<column name="EMAIL"/>
</property>
</class>
</hibernate-mapping>
my FirstExample is :
/**

*/
package roseindia.tutorial.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
/**
* @author shabarish

*/
public class FirstExample
{
public static void main(String as[])
{
Session session=null;
try {
//used to read hibernate.cfg.xml file
SessionFactory sessionFactory=new Configuration().configure().buildSessionFactory();
session=sessionFactory.openSession();
System.out.println("inserting records in Contact table");
Contact contactBO = new Contact();
contactBO.setId(5);
contactBO.setFirstName("nissan");
contactBO.setLastName("Bugati");
contactBO.setEmail("nissanB[email protected]");
session.save(contactBO);
System.out.println("After Save");
} catch (Exception e)
{
// TODO: handle exception
System.out.println(e.getMessage());
}finally{
// Actual contact insertion will happen at this step
session.flush();
session.close();

}

}
}
and my contact table is:
CREATE TABLE `contact` (
`ID` int(11) NOT NULL,
`FIRSTNAME` varchar(50) default NULL,
`LASTNAME` varchar(50) default NULL,
`EMAIL` varchar(50) default NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
data is not inserting into DB

Hi,

Just for testing that you are doing everything right and to see that data is being inserted into table,modify the code mentioned in the firstExample as below.
I will later post the actual code issue later.
here i am using transaction interface to make things work for you hope this helps.

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

try{
// This step will read hibernate.cfg.xml
//and prepare hibernate for use
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
session =sessionFactory.openSession();
Transaction tx = session.beginTransaction();

//Create new instance of Contact and set
//values in it by reading them from form object
System.out.println("Inserting Record");
Contact contact = new Contact();
contact.setId(3);
contact.setFirstName("Deepak");
contact.setLastName("Kumar");
contact.setEmail("[email protected]");
session.save(contact);
System.out.println("Done");
tx.commit();

// session.flush();
session.close();
}catch(Exception e){
System.out.println(e.getMessage());
}finally{
// Actual contact insertion will happen at this step


}

}
}
