Have no clue with LogFactor 5.

Maybe some of Chainsaw's history might help.  Chainsaw previously used  
log4j 1.3 (now abandoned) which had an incompatible serialization  
format for events.  Chainsaw would then see locations from log4j 1.3  
apps, but not from log4j 1.2 apps.  Chainsaw has been migrated back to  
being based on log4j 1.2 + companions which contain backports of log4j  
1.3 features that it used, but it has not been pushed for release (on  
my list after log4cxx and cpptasks) which will now receive location  
from log4j 1.2 and log4cxx apps, but will lose the location from log4j  
1.3 apps.

I'm guessing that your LogFactor 5 might be based on log4j 1.3.

Sorry I can't help more than that.  Can your LogFactor 5 see events  
from a log4j 1.2 app?

Also, are you using the LOG4CXX_INFO et al macros.  If you are just  
doing logger->info("Hello, World"), no location information is  
available and there is no (at least no portable way) to get it from  
the context.
