I suggest you have a look at the Telecom Logging Service. It sounds like
a close fit for your requirements.

1. Web Services error handling

I have created a module that will be accessed via web services.  However I
also want to be able to call if from a standalone program.  I am stuck
thinking about error returns from database calls, which usually have a 'or
die' error processing routine, which is fine for a standalone situation.
When the module is called via web services I want to call a fault routine
rather than the 'or die' routine for standalone access, but I can't quite
figure out how to accomplish this in Perl.


databaseaccess->function (string)
    or die (didn't work);  #standalone situation
if (webservices call) load fault structure and return. #web services
situation, returned to client program

I'm sure I'm not the first to come across this, and I'm sure there is an
elegant way to accomplish it.  Can someone point me in the right direction?
