Exception Handling

[gfalco77]

Hi!

I'm developing a Spring MVC web app following the stack:
@Controller
@Service@Transactional
@Repository

I inserted the org.springframework.dao.annotation.PersistenceExce ptionTranslationPostProcessor in my applicationContext.xml

and in my spring-servlet:

    <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <property name="exceptionMappings">
            <map>
                <entry key="DataAccessException" value="dataAccessFailure"/>
            </map>
        </property>
    </bean>

I found out that if in my controller i call directly the DAO the DataAccessException is caught, while if I use the service it does not.
It can be obvious because it is raised an unchecked exception, but the question is: How to propagate the DataAccessException in order to be caught by the SimpleMappingExceptionResolver?

Should I have to use a try catch(DataAccessException) block in the service? I tried but it's not caught..

Another question: where is it useful insert log? In the DAO or in the service?
What is the best practise?

Thank you in advance

If i insert

<error-page>
        <exception-type>java.lang.Exception</exception-type>
        <location>/WEB-INF/jsp/dataAccessFailure.jsp</location>
    </error-page>

In my web.xml .. it's showed the /web-inf/jsp/dataaccessfailure.jsp outside my tiles ..

Should runtimeexception be propagated to the controller passing via Service layer?
