I am integrating spring and hibernate.

    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"

    </bean>

    <!-- Detect @Transactional Annotation -->
    <tx:annotation-driven transaction-manager="transactionManager" />

</beans>

And here is Books pojo:

@Entity
@Table(name = "books")
public class Books implements Serializable {

    @Id
    @GeneratedValue
    private Integer id;
    @Column(nullable = false)
    private String title;
//other methods
}

But hibernate can't create table with name books in database obs.

database obs is present.
