RE: Announcement: Just4log, a performance-oriented postprocessor
for Log4j
Lucas,
We can certainly add a reference on the log4j pages (though Ceki might have
to do it since I do not have the Anakia tool set up on my machine right
now). You might also want to announce this tool on the log4j-user email
list.
Also, something else that has been bandied about as a neat feature is the
ability to instrument the code with debug statements to mark when a method
is entered/exited. For a future version, you might want to look into adding
this as well.
thanks,
-Mark

Hi,
I like very much AspectJ... It is great new way of developping. But then
not every project can do aspect oriented-developpment. Some because they
have legacy code to maintain, other because they have a boss who has decided aspect-oriented developpment is too new to be used right now.
( This kind of decision can be quite political.)
Now I think I can easily implement this feature in a simple-to-use Ant task, so I'll probably do so soon, before every one has migrated to AspectJ.
Cheers,
Lucas

A tool that is more appropriately shaped for that particular job is
probably AspectJ <http://www.aspectj.org>.

Hi Mark,
Just4log now does the requested feature in R0_4.
( Just released)
( entered and exited log statments)
Cheers,
