Ceki,
I found a way to solve my problem without changing the code for SocketServer
or SocketAppender (thank you Seemantini Godbole). I created a generic.lcf
and added some categories and stated one log file per category (see below).
I want to separate logging per session bean type. Aktually per group of
session bean types.
I don't see how NDC could help. It doesn't have any mechanism to create
several log files. It's for adding some extra info to the output. Am I
right?
I dont really understand you when you say "you cannot guarantee that the
code called by the session beans will be in x or respectively y".
In the EJB's I do theese two rows every time i log something:
Category cat = Category.getInstance("EJB1");
cat.info("message");
Then I can be sure that it writes to the right file.
Is this a good way of using log4j? I hope that I have explained
understandably.
Best Regards and thank you for your help.
