1. Re: JBOSS log rotation
jaikiran Nov 21, 2008 5:53 AM (in response to ran_sushmi)The log4j.xml is supported by the Log4j framework. The Log4j manual http://logging.apache.org/log4j/1.2/manual.html will help you get started with this.

ran_sushmi Nov 24, 2008 3:21 AM (in response to ran_sushmi)hi,
thanks, for your answer. This was helpful, but there is this code in our JBOSS application 'log4j.xml' file which is difficult to understand. I am pasting the initial contents of the file off which I am not able to make out much. The contents are:-
-------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

Can, the lines of the code be explained. By the way, is there any way to upload a file on the forum.
I hope, my question is clear.
Please, help in solving the doubt.

By the way, is there any way to upload a file on the forum.
No, the forum does not have that support. -

5. Re: JBOSS log rotation
jaikiran Nov 24, 2008 6:33 AM (in response to ran_sushmi)The log4j configuration file that you posted, creates multiple appenders and then associates the loggers with these appenders. Is there any specific part which you did not understand in that file?

hi,
thanks, for your answer. I guess, the only thing that I could make out clearly were the lines,
--------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------
which say that the contents will not be appended to the server.log file on re-start.
But, against the contents of the file that I posted, it would be very helpful if you could just write comments on the side.
regards.
