I would appreciate any insights people have on the best way to handle
exceptions. I would really like to keep it simple, and not create a
custom exception handler or whatever if I don't need to.
I ran across ModuleException, mentioned in the Jakarta Struts book by
Cavaness (2nd ed for struts 1.1). This seems like a fairly pain-free
way to throw an exception that is wrapped around an ActionError,
providing for localized error messages.
However, the author warns that using this ties your application to
struts. Is this really a big problem? I don't think I'm going to be
handling exceptions in my business code, only in the controller code.
(The business code may throw them; I don't plan to handle them until
they bubble up to the controller.) (Of course, please let me know if
this is a bad idea.) The controller code is, obviously, already tied to
struts! So I see this warning as a non-problem. Am I missing something?
I plan to use declarative exception handling, hopefully in combination
with ModuleException. At some point, I will end up in a jsp page and
need to print out the contents of the ActionError within the
ModuleException. Does anyone have an example of how to do this?
Thanks again for the list's help!
