Im using Hibernate with Annotations.

This is my entity class;
===============

import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;


@Entity
@Table(name="ORDER_OF_SALE")
public class OrderOfSale implements Serializable {

getters and setters goes here.

}


This is my hibernate utilization;
====================

public String hibInsert(Object tblObj) throws Exception{
Session session = null;

AnnotationConfiguration ac = new AnnotationConfiguration();
session = ac.configure().buildSessionFactory().openSession();


if (tblObj != null) {
try {
Transaction beginTransaction = session.beginTransaction();
session.save(tblObj);
beginTransaction.commit();

if (beginTransaction.wasCommitted()) {
return "1210";
//response.sendRedirect("index.jsp");
} else {
return "Operation failed";
}
} catch (HibernateException hbe) {
return "Operation failed " + hbe.toString();
} finally {
session.flush();
session.close();
}
} else {
return "Required fields are not filled";
}
}

;;;;;;;;;;;;;;;;;;;;;

In above function tblObj is saved as POJO. The attribute values want to set to above 'OrderOfSale' class.

Everything is ok, but executing 'session.save(tblObj);' it gives this error message.

'Operation failed org.hibernate.MappingException: Unknown entity: com.aura.data.trn.OrderOfSale'

I think my Entity class has defined well, but i cannot solve this problem.
Please help me.

Thanks,
Dilan Alex

Could you please post Hibernate Configuration( hibernate.cfg.xml) also.

I think that it is because in your OrderOfSale class you are using the JPA (javax.persistence) classes, but in your other code you are accessing the native Hibernate Session etc.

If you use JPA, then you should be using an EntityManager instead.

My understanding is that you have added this entity class in Hibernate Configuration file by using <mapping resource="entity class path"/> element.


As you have annotate the entity class by @Entity, you should map it using <mapping class="full entity class path"> in Hibernate Configuration file.

Thank you all of you for reply. I didn't add mapping for the appropriate class.
That is the reason for this problem.

I added mapping for the 'OrderOfSale' class in 'hibernate.cfg.xml'. And problem solved.
