<bean id="transactionManagerCustomer1"

<property name="dataSource" ref="customer1DataSource" />
</bean>

<tx:annotation-driven transaction-manager="transactionManagerCustomer1"
mode="proxy" />


<tx:advice id="txUserDetailsDTO" transaction-manager="transactionManagerCustomer1">
<tx:attributes>
<tx:method name="*" read-only="false" />
</tx:attributes>
</tx:advice>

<aop:config>
<aop:pointcut id="configService"

<aop:advisor advice-ref="txUserDetailsDTO" pointcut-ref="configService" />
</aop:config>

<bean id="userDetailsDao" class="com.kumaran.testing.TestDAO">
<property name="sessionFactory" ref="customer1SessionFactory" />
</bean>

</beans>

But when i tried like this in my DAO
public class TestDAO extends HibernateDaoSupport {
public void getDetails() {
UserDetailsDTO userDetailsDTO = new UserDetailsDTO();

userDetailsDTO.setName("Karthik");
userDetailsDTO.setDescription("Customer4");
getHibernateTemplate().save(userDetailsDTO);

}}
it throws NullPointerException.What i have to change in my code.Thanks in advance.
