Hello i am new to hybernate. . .
i have created a sample project ..

Employee.java

Code:

package com.mycompany.HybernateTry7;

 

import java.io.Serializable;

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

@Entity
@Table(name = "EMPLOYEE")
public class Employee implements Serializable {
   public Employee() {

   }
   @Id
   @Column(name = "id")
   Integer id;

   @Column(name = "name")
   String name;

   public Integer getId() {
      return id;
   }

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

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }

}

HybernateUtil.java

Code:

package com.mycompany.HybernateTry7;

 

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

public class HibernateUtil {
   private static final SessionFactory sessionFactory;
   static {
      try {
         // Create the SessionFactory from hibernate.cfg.xml
         sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
      } catch (Throwable ex) {
         // Make sure you log the exception, as it might be swallowed
         System.err.println("Initial SessionFactory creation failed." + ex);
         throw new ExceptionInInitializerError(ex);
      }
   }

   public static SessionFactory getSessionFactory() {
      return sessionFactory;
   }
}

Example1.java

Code:

package com.mycompany.HybernateTry7;

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

public class Example1 {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        /** Getting the Session Factory and session */
        SessionFactory session = HibernateUtil.getSessionFactory();
        Session sess = session.getCurrentSession();
        /** Starting the Transaction */
        Transaction tx = sess.beginTransaction();
        /** Creating Pojo */
        Employee pojo = new Employee();
        pojo.setId(new Integer(5));
        pojo.setName("XYZ");
        /** Saving POJO */
        sess.save(pojo);
        /** Commiting the changes */
        tx.commit();
        System.out.println("Record Inserted");
        /** Closing Session */
        session.close();
    }
}

Hybernate.cfg.xml

Code:

<?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">
<hibernate-configuration>

        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.current_session_context_class">thread</property>
    </session-factory>
</hibernate-configuration>

i am getting following exception

Add one more line in Hybernate.cfg.xml

Code:

I think you are using Oracle as Database server, Then change the value of "hibernate.dialect" from

Quote:

org.hibernate.dialect.DerbyDialect

Quote:

org.hibernate.dialect.Oracle9Dialect

Do you have a mapping file for javaapplication42.Employee?

I think your AnnotationConfiguration needs to be told where to look for annotated classes, which the mapping in your XML probably should have achieved.

You could try removing that from the XML and doing it programmatically instead by restructuring your HibernateUtil setup slightly, along the lines of:

AnnotationConfiguration config = new AnnotationConfiguration();
config.addClass(javaapplication42.Employee.class);
sessionFactory = config.buildSessionFactory();

I got the same error i simply solved it by adding <mapping resource="com/hiber/annot/Employee.hbm.xml"/> in cfg.xml file
