Errors in named queries Spring 3.x + JPA + Hibernate

Hi

I am getting following error while deploying on Tomcat

org.hibernate.HibernateException: Errors in named queries: findDSByName

I have defined Named query as

@Entity
@Table(name = "DATASTORE")
@NamedQuery(
name = "findDSByName",
query = "FROM Datastore WHERE DSNAME=?")

Complete error stack
