java.sql.SQLException: ORA-06576: not a valid function or procedure name - spring

Question

When saveDepartment() is invoked, I am getting exception mentioned in the title. After searching for solution for a while I came up with another similar post on stackoverflow which doesn't match the problem scenario I am facing.
Dao class:
#Repository
public class DepartmentDaoImpl implements DepartmentDao {
#Autowired
private SessionFactory sessionFactory;
#Override
#Transactional
public void saveDepartment(Department department) {
Session session = sessionFactory.getCurrentSession();
session.save(department);
}
}
Bean configuration section for hibernate:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="packagesToScan" value="net.therap.domain.tmp"/>
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect"> org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
Any suggestion or solution regarding the problem is appreciated.

Answer 1

ORA-06576 error code and oracle11g tag are suggesting you're using Oracle 11g Database.
Hibernate's Oracle10gDialect is compatible with that version, so you should use following dialect configuration:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="packagesToScan" value="net.therap.domain.tmp"/>
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
