Here's what I do ... add the line
use Carp;
to your Module list (checkout the perldocs on it for full details)
Wrap your call in an 'eval {};' block. Example ...
eval
{
System.call (...); # This is the call that you're expecting an
error from
}; ## Don't forget the semi-colon
if ( $@ )
{
$r->print ( "Uh oh. Error found: $@" );
carp ( $@ );
}
The eval acts as an exception handler. There is some discussion on the
mod_perl site for using eval and Carp for exception handling.
Hope the helps.
