There was an example of this a couple weeks ago on the mailing list.
The recommended solution then was to set System.out and System.err to
a new PrintStream that you control. Then you read lines from the
PrintStream and log messages using log4j.

Yes. That is what I asked in my original email. Any sample
applications/guidelines, which will not break any of my 3
requirements ?

Maybe you could create an application that will read all the outputs
of your
old application and throw the messages using log4j!

Not exactly. It has got lots and lots of system.out messages.

The application is sending the messages thru log4j ConsoleAppender?!

Just wanted to add that, the application redirects lot of messages
to
stderr also and they also should be logged in the same log file.

OS Linux:
Am using an application which redirects lot of messages to stdout
I do not have access to the source code of this application.
I would like to log4j these messages through RollingFileAppender.
Requirements:
1) The no of lines to be logged are very high and very fast rate.
2) The new logging mechanism should not have any impact on the
performance
of
the application or the system
3) Not even single line of the message should be missed.
Could someone please let me know, what is the best way to achieve
this ?
TIA
