This question seems to be repeated but i tried all possibilities i could do but not able to resolve this error. please help me i am beginner in Hibernate.

-FirstProject

--->src

  ------>myPackage

       --> Employee.java
       --> StoreData.java

--->Employee.hbl.xml

--->hibernate.cfg.xml

Both xml files are under src folder and here my code goes

package mypackage;

**public class Employee** 
{

    private int id;
    private String FirstName,LastName;

    public int getId()
    {
        return id;
    }

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

    public String getFirstName()
    {
        return FirstName;
    }

    public void setFirstName(String FirstName)
    {
        this.FirstName=FirstName;
    }

    public String getLastName()
    {
        return LastName;
    }

    public void setLastName(String LastName)
    {
        this.LastName=LastName;
    }
}

Employee.hbl.xml

<class name="mypackage.Employee" table="emp1000">  

   <id name="id">  
      <generator class="assigned"></generator>  
   </id>       
   <property name="firstName" column="fname" type="String"></property>  
   <property name="lastName" column="lname" type="String"></property>   

 </class>

<session-factory>  
    <property name="hbm2ddl.auto">update</property>  
    <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>  
    <property name="connection.url">jdbc:oracle:thin:@localhost:1521:xe</property>

</session-factory>  

StoreData.java

package mypackage;

public class StoreData { 

    public static void main(String[] args) {  

        SessionFactory sF = new Configuration().
                configure("/First/src/mypackage/hibernate.cfg.xml").buildSessionFactory();

        Session session=sF.openSession();  
        Transaction t=session.beginTransaction();  
        Employee e1=new Employee();  
        e1.setId(115);  
        e1.setFirstName("Madu");  
        e1.setLastName("biradar");  
        session.persist(e1);
        t.commit();  
        session.close();  
        System.out.println("successfully saved");  
        }  
    }  

Thanks to all who would give any sort of suggestion...
