log4j.xml

[Amir Iqbal]

Hi,
can anyone please tell me (in details) about how to configure the log4j so that it logs
the requests of diffrent users in diffrent .txt files (file name should be same as that of username
eg john.txt maria.txt etc)
i have heard something about NDC(Nested Diagnostics Context) But unfortunately i am unable
to find complete step by step tutorial(example) to use NDC.

so please help me out

All kinds of solutions and suggestions are appreciated
Regards
Amir Iqbal
