Handling exceptions

[dpgaspar]

Hello,

I would like to handle constraint violations, when the user delete a registry that is referenced by a foreign key.

What is the best way to do this. I would like to use something like "uncaughtException.jspx" but specific to this.

I guess this is very simple, but if anyone can help?

I am looking for something that does not include DAO, and that it's more Spring framework like.

I am trying something like this on webmvc-config.xml:

<bean class="org.springframework.web.servlet.handler.Sim pleMappingExceptionResolver" p:defaultErrorView="uncaughtException">
<property name="exceptionMappings">
<props>
<prop key=".ConstraintViolationException">constraintViol ation</prop>
<prop key=".DataAccessException">dataAccessFailure</prop>
<prop key=".NoSuchRequestHandlingMethodException">resour ceNotFound</prop>
<prop key=".TypeMismatchException">resourceNotFound</prop>
<prop key=".MissingServletRequestParameterException">res ourceNotFound</prop>

</props>
</property>
</bean>


But the exception is not caught !!
