exception handling under Apache::ASP

[Peter Beardsley <pb...@appropriatesolutions.com>]

Hi,
This might be a more general mod_perl question, and if so let me know, 
but I'm trying to add exception handling to my Apache::ASP code.  
Basically I have a module that encapsulates all my data access, with all 
the UI logic handled in ASP pages.  What I want to do is throw 
exceptions in the data module, and catch them in the ASP pages.  I've 
been using Error::Simple and throwing errors in the data module like so:

    throw Error::Simple( 'My Error');

the calling code in the ASP page looks like so:

    try {
      Data::DataRoutine();
    }
    catch Error::Simple with {
      my $E;
      $Response->Write($E);
    }

But the throw always triggers an Apache error and gets written to the 
Apache log.  I've also tried the module Exception::Class with similar 
results.

Can anybody with experience doing exception handling under Apache::ASP 
tell me what works for them and point me in the right direction?

Thanks,
-Peter.

Well, I'm pretty old fashioned in this regards, but I rely on die() for
my error throwing, and eval {} for my error catching, and just check
for whether $@ exists after the eval {} to see if there was an error.

BTW, sorry for not getting back for so long.  I am been swamped with
work recently.

Regards,

Josh
