I ran into this problem myself, Sre, and happily, I found a solution that
works.
IF you are going to wrap log4j's wrapper Logger class with your own wrapper
class, in this case, your Log4j class, you need to make sure that your
wrapped class calls this form of Logger.log:
--- paste from log4j javadoc ----
public void log(String callerFQCN,
Priority level,
Object message,
Throwable t)
This is the most generic printing method. It is intended to be invoked by
wrapper classes.
Parameters:
callerFQCN - The wrapper class' fully qualified class name.
level - The level of the logging request.
message - The message of the logging request.
t - The throwable of the logging request, may be null.
-- end paste --
Make sure you pass your wrappers class name in the callerFQCN arg, and then
log4j will be smart enough to get the line and filename information to the
appender.
Hope this helps.
