writing to ant's logger from external type

[Loehr, Ruel]

I've written a task which uses a custom data type.   I'd like to be able to 
write log messages from within that type using ANT's logging mechanism.   If I 
use that type independently, I'd like to just write to System.out.

Does anyone know of a way to pass ants logger to an external type such that I 
could do something like this:


If (logger !=null)
            Logger.LogMessage("My message");
Else
            System.out.println("My message");


Thanks!
