org.hibernate.HibernateException: Errors in named queries

[surendra harikantra]

Im using JPA with hibernate. Im able to insert record into db using JPA.
when im trying retrieve record from DB using NamedQuery, im getting javax.persistence.PersistenceException: [PersistenceUnit: wsrdatabase] Unable to build EntityManagerFactory
Am i missing something? please help me in that.
Entity bean:
@Entity
@Table(name = "employee")
@NamedQueries( {
@NamedQuery(name = "employee.findAll", query = "SELECT e FROM employee e"),
@NamedQuery(name = "employee.byId",
query = "SELECT e FROM employee e WHERE e.employeeNum = :empNum") })

public class Employee
{

@Id
@Column(name = "employeeNum", nullable = false, unique = true)
private String employeeNum;

@Basic
@Column(name = "firstName", nullable = false, unique = false)
private String firstName;
.
..
// class using entity bean
public List<Employee> searchAllEmployee() throws EmployeeException
{
EntityManagerFactory entityManagerFactory = Persistence.
createEntityManagerFactory( Constants.PERSISTENCE_UNIT );
EntityManager entityManager = entityManagerFactory.createEntityManager();
Query findAllQuery = entityManager.createNamedQuery("employee.findAll");
List<Employee> employees = findAllQuery.getResultList();
return employees;
}
//persistence.xml
<persistence-unit name="wsrdatabase">
<provider>org.hibernate.ejb.HibernatePersistence</provider>

try using

@NamedQuery(name = "employee.findAll", query = "SELECT e FROM Employee e"),
