CGI:Application "error"

neptuneray has asked for the wisdom of the Perl Monks concerning the following question:

I have a CGI:Application running on Apache/mod_perl. Everything works, except when I get any sort of error. The application terminates with a 500 code, and I get the following message:
"Can't locate object method 'error' via package "Template::Exception" at /usr/local/lib .../CGI/Application/Dispatch.pm line 438."

In my Setup sub (where Run Modes are defined), I am setting "$app->error_mode('error')", and then I have my own sub named "error" in that module.

Is it me that is doing something wrong, or is this an internal module error that I have no control over?

Oh, and one more thing ...

In my own error sub, I am trying to use the $app object to call "tt_process" to display my error template.

Possibly I don't have access to the $app object?

In reading the docs, I see that I only get $@ passed.

Does this mean I get to write directly to the client (an otherwise no-no in CGI:Apps)?

Thanks much, Ray

and one more thing ... In my own error sub, if I print the variable that is passed to me ($@, according to the doc), I get "Got error: JCS::Shop=HASH(0x6343538)" where "JCS::Shop is the module where this error happens. I have NO IDEA of what this is telling me! In the example in the doc, they get a nice clean error message, like "Illegal division by zero", etc. Thanks again, Ray	[reply]

`JCS::Shop=HASH(0xDEADBEEF)` and the like happen when you stringify a hash reference blessed into the JCS::Shop package. In this case, you'll probably want to pass $@ to `Dumper` in Data::Dumper to see what's actually stored in the variable. See Basic debugging checklist. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l] [select]

Thanks for the help. I am now reading a proper Perl error message. But that doesn't mean I'm out of the woods! Looks like I've got some tricky bug lurking somewhere in some module ... oh, well ... sometimes I regret having given up the slide trombone for a career in IT ...	[reply]
