Hello... I have 2 classes: one is a threaded class and the other is my
main class. My main class will execute 3 instances of the threaded
class simultaneously. How will I log these 3 threads SEPARATELY? Please
help . . . Thank you . . .

Can you post your code?

The simplest solution would be to have your main class create three
different Log instances and pass them to the three different threaded
instances in their constructors.

Depends on what you mean by separately. With log4j you could also use
a single log instance logging to a single file and distinguish the log
entries by the Thread IDs (e.g. using Nested Diagnostic Contexts).

Hello, Mr. Sebastian. Is it really safe to use Nested Diagnostic
Contexts? I found this article "Think again before adopting the
commons-logging API" in http://www.qos.ch/logging/thinkAgain.jsp ...
Sorry, I'm not familiar.

Well, that article is concerned with using commons logging,
which doesn't support Nested Diagnostic Contexts, which are
a feature of log4j. -- Sebastian
