RE: Logging from a Windows Service

I'll try all of these things, but I do believe that the privileges are OK, 
since something like:

Service.exe /service params

Run from the command prompt logs fine, creating the file in the place I'd 
expect it to be.  I already suspected that it didn't know where to resolve the 
configuration file, so I used an explicit path (C:\\....\\configuration.xml), 
so I don't think that's the issue.  I also leave the logger reference around, 
so I'm actually using the same Logger variable the second time (when it fails) 
as I did when it worked the first time (from the command line).

BTW, I'm using CVS HEAD from about 2/22.

Not enough information to go on really.

Are you using 0.9.7 or CVS HEAD?

Are you using relative paths in your configuration?  They might be 
getting resolved to unexpected paths.

Have you tried using OutputDebugAppender and monitoring the service 
with DebugView 
(http://www.sysinternals.com/ntw2k/freeware/debugview.shtml) or other 
Debug monitor?  That would at least allow you to check that 
configuration works as expected and then progress to figuring out why a 
particular appender isn't working as expected.

log4cxx doesn't do any trickery with privileges, the process has to 
have the rights to create and write to the log file.
