Hi !
I want to find out what is best thing to do when it comes to
Exception Handling?
I have my Application specific AppException I create many
different sub-class of AppExceptions based on different conditions
in my application.
In struts config I am trying to put exception with All Action with
AppException ( My base Application specific Exception )
<action
path="/sectorProcess"
name="sectorForm"
type="web.action.SectorAction"
scope="request"
parameter="dispatch">
<exception
key="SessionExpiredException"
type="web.exception.AppException"
path="/sessionExpired.jsp" />
1. In my DAO/DTO/Business layers should i keep on propagating
exception upto Action class.
In my Action I have put try/catch for generic Exception,
so all known exception including my AppException are caught and logged.
Struts frame work will redirect to AppException related
jsp.
OR
2. When ever exception happens in DAO/DTO/Business layers I
catch it there Make my application specific Exception without
propagating to all the way upto Action class because
Struts frame work would redirect to AppExcpetion jsp based on
struts-config.
Pls. advise !
Thanks.
