createData java looks like

package roseindia;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

public class CreateData {


public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub

SessionFactory sessFact = HibernateUtil.getSessionFactory();
Session sess = sessFact.getCurrentSession();
org.hibernate.Transaction tr = sess.beginTransaction();

Student stu = new Student();
stu.setSname("Ganesh");
stu.setSroll(100);
stu.setScourse("B.C.A.");

sess.save(stu);//Save data
tr.commit();
System.out.println("Successfully inserted");
//sess.close();
}

}



student.java looks like


/**
*
*/
package roseindia;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import javax.persistence.Table;;

/**
* @author Rose India
*
*/
@Entity
@Table(name = "student")

public class Student implements Serializable{


@Id
@GeneratedValue

private int id;
public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

@Column(name="sname", nullable=false,length=40)
private String sname;
public String getSname() {
return sname;
}

public void setSname(String sname) {
this.sname = sname;
}

@Column(name="sroll",nullable=false)
private int sroll;
public int getSroll() {
return sroll;
}

public void setSroll(int sroll) {
this.sroll = sroll;
}

@Column(name="scourse",nullable=false,length=10)
private String scourse;
public String getScourse() {
return scourse;
}

public void setScourse(String scourse) {
this.scourse = scourse;
}

}



hibernate.cfg.xml looks like

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

<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">none</property>

<mapping class="roseindia.Student"/>

</session-factory>
</hibernate-configuration>



hibernate util class looks like


package roseindia;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {
//Singleton class
private static final SessionFactory sessionFactory;
static{
try{
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
}catch(Throwable th){
System.err.println("Enitial SessionFactory creation failed"+th);
throw new ExceptionInInitializerError(th);
}
}

public static SessionFactory getSessionFactory(){
return sessionFactory;
}

}


I was able to insert values outside hibernate through regular java program without any issues.

Any links, resources, ideas, sample code highly appreciated. Thanks in advance
