Who called a CFC

Question

is there a way to find out who invoked a CFC? I would like to
check and log who the calling .CFM or .CFC file is from within the
CFC being invoked. Sort of like back in the Custom Tag days, I need
to know which templated called me. I am looking at the
GetMetaData() and GetPageContext() functions but nothing stands out
yet as how to do what I need to do.
Thanks All for the Posts below,
This is a pretty tough one, and I wish I could diagram it to
help explain.
cfc1
cfc2
cfc55
In any of these CFC's, we have code wraped in try/catch
statements. When an exception is thrown, the catch statements kick
in. in the catch blocks, I invoke a cfc called myErrorCFC.cfc..
err = createObject("component", "myError");
From there inside of the catch block I am invoking a method
(see below) which performs legancy handling/logging.
err.parseException(cfcatch.Message);
What I now need to do is extend that method to log who thrown
the exception. Yes the simple way is to pass the name of the cfc or
cfm page as an argument, but changing the code which invokes the
err cfc is out of my control. So I am left with trying to solve
this the hard way.
So far this is where I am at (in my "myErrorCFC.cfc", invoked
from within the catch blocks) which is not currently working:
tmp = getPageContext().getException();
This does not work but it may clearify the approach I am
taking. Does anyone have any good ideas on how to return the error
object from the JRun/jsp/java side of things. "getPageContext()"
returns a "coldfusion.runtime.NeoPageContext" object. The end
result I am trying to achieve is simply (ha ha) to find out which
cfc or cfm page that the exception was thrown and having access to
any additional info would be benificial as well.
Any help will be appriciated greatly.
Thank you,
Erik

Thx for your response, passing an argument would idealy be
the simplest approach but in the context of the problem it would
not be posible. I am working with a VERY large application and to
do so would mean modifying hundreds of lines of code where the CFC
I'm invoking is called from throughout the system. With large
legancy systems as you know, it's always exceptable to make
sweeping changes through sensitive code. If I end up not being able
to find a method in which to find who invoked the CFC I am
modifying I will just have to live with the fact. Idealy I want to
be able to track and log who it was that initiated the CFC. That
can come from a number of model cfm files or cfc's.
