Spring Transaction not rolling back

Question

I have something like this:

@Service
@Transactional
public class ServiceA {

    @Autowired
    SomeDAO1 dao1; 

    @Autowired
    ServiceB serviceB;

    public void methodServiceA() {

        serviceB.someMethodThatRunsInsertIntoDB(); 
        dao1.anotherMethodThatRunsInsertIntoDB(); 

    }

}

@Service
@Transactional
public class ServiceB {

     @Autowired
     Dao2 dao2;

     public void someMethodThatRunsInsertIntoDB() {
          dao2.insertXXX();
     }

}

My problem is: if serviceB.someMethodThatRunsInsertIntoDB() executes sucessfully but dao1.anotherMethodThatRunsInsertIntoDB() throw an exception, the changes made by serviceB are not rolled back. I need to rollback those changes in case an exception occur in dao1.anotherMethodThatRunsInsertIntoDB(). How can I do this?

Transaction configuration in spring-servlet.xml

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
    </property>
</bean>

Is it relevant if one dao uses an EntityManager and the other dao uses JdbcTemplate to interact with DB?

//UPDATE -- EntityManager configuration

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true" />
            <property name="generateDdl" value="true" />
        </bean>
    </property>

Answer 1

you need to pass rollbackFor parameter with type of your checked exception. It seems that spring rollbacks only on unchecked exceptions by default. More details: Spring transaction: rollback on Exception or Throwable
