No problems... another Appender choice for Log4J
users is always welcome. ;)

hierarchies, and how?
Chris,
I see a few issues with this solution. I
also thought of this, however.
1. Each worker thread makes
use of other shared objects. Each of these "utility" objects
have their own category. If I were to use your suggestion,
each "utility" object would have to create a thread unique category, which
would cause a proliferation of categories. Instead of having a category per
class, I would now have a category per class per thread.
2. Since the thread ids are
generated at runtime, there would be no way to configure the categories
through a configuration file.
I'm looking forward to the ThreadAppender that
Jim Moore is working on.
Thanks for the feedback.

Wouldn't the easiest way to accomplish this is
create Category and Appender for each new Thread as it enters the pool
(where the name of the category and appender are the unique thread
identifier assigned in the constructor):
Thread t = new
Thread(xxxSomeRunnablexxx,"xxxSome Thread Id");
Category cat =
Category.getInstance("xxxSomeRunnablexxx");
FileAppender appender = new
FileAppender(xxxSomeLayoutxxx,"xxxSome Thread Id"+".log");
cat.addAppender(appender);
And then from within the thread:
Thread t =
Thread.currentThread();
Category cat =
t.getInstance(t.getName());
cat.ERROR(xxx); // or
whatever
That would probably be the easiest way to do
this without making changes to Log4J.

Jim,
No actually not. I had not fully read the
question previously. I don't think log4j is designed for thread based
logging. This had never come up before. Regards, Ceki
