HI I am getting the below error when I try and run some code using HIBERNATE.

INFO: HHH000221: Reading mappings from resource: com.hibernate007.pkg.Employee.class
Exception in thread "main" org.hibernate.MappingNotFoundException: resource: com.hibernate007.pkg.Employee.class not found

Below given all the codes that I have written.

hibernate.cfg.xml

<?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>

<session-factory>

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/hibernatedata</property>

<property name="connection.password">password</property>
<property name="hibernate.show_sql">true</property>
<mapping resource="com.hibernate007.pkg.Employee"/>
</session-factory>

</hibernate-configuration>

POJO class

package com.hibenate007.pkg;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Employee {

private int empid;
private String empname;
@Id
public int getEmpid() {
return empid;
}
public void setEmpid(int empid) {
this.empid = empid;
}
public String getEmpname() {
return empname;
}
public void setEmpname(String empname) {
this.empname = empname;
}


}

SessionFactory Class

package com.hibenate007.pkg;


import org.hibernate.*;
import org.hibernate.cfg.Configuration;
public class MySessionFactory {

static Session getSession(){
Configuration conf = new Configuration();

conf.configure("hibernate.cfg.xml");
@SuppressWarnings("deprecation")
SessionFactory sf = conf.buildSessionFactory();
return sf.openSession();
}

}

And finally the calling class(Client Program)

package com.hibenate007.pkg;


import org.hibernate.Session;


public class ClientProgram {


public static void main(String[] args) {

Session session = MySessionFactory.getSession();
session.beginTransaction();
Employee emp =new Employee();
emp.setEmpid(1);
emp.setEmpname("aneek");
session.save(emp);

session.getTransaction().commit();

session.close();



}

}


I am a newbie to Hibernate.Please help me to solve this I am trying to figure this problem for last 2 days.Even checked in internet also but not accquired any proper steps.

Please help ASAP.

Thanks in advanced. :)

Hi Aneekbanerjee86 and welcome to Hibernate.

The problem is in the following code:

<mapping resource="com.hibernate007.pkg.Employee"/>

It needs to be mapped an "hbm.xml" file that is available in the package you mapped, meaning "com.hibernate007.pkg", and it should use a slash ("/") notation and not a dot (.) notation.
So create an "Employee.hbm.xml" file in the package "com.hibernate007.pkg" and change the mapping to "com/hibernate007/pkg/Employee.hbm.xml".

There is also a nice tutorial in: "http://ejbas-hibernate.blogspot.co.il/", that explains how to use Hibernate in a really neat and detailed step-by-step.

Good luck
