I'm looking to get a handle on best exception handling practices in my app.
Kinda beginner question i guess, sorry.
Im catching the various sql and naming exceptions in the data classes and
logging and throwing a custom exception called ApplicationException which is
blank and provided below. I've read up but an still a little confused on how
exactly to build this exception class to extend the available struts exception
classes that would gracefully map to an error display jsp where i could display
the error to the user. Right now I just get the HTTP status 500 strack trace
on the screen.
Controller snippet that catches the data obj's thrown ApplicationException:
------------------------------------------------------------------------
try {
zRepBeanBn =
MyData.getRepByID(StringUtils.convertToInt(request.getParameter("RepID")));
}catch (ApplicationException zAppEx){
throw zAppEx;
}
------------------------------------------------------------------------
ApplicationException that needs work: How do I extend this?
------------------------------------------------------------------------
public class ApplicationException extends Exception {
public ApplicationException(String message) { }
}
------------------------------------------------------------------------
Thanks
