I tried using
new PropertyConfigurator().doConfigure(properties, LogManager
.getLoggerRepository());
But still the configuration is not getting reflected !
Any idea?

Or in other words
I want to do
PropertyConfigurator.reconfigure(Properties prop);
Is there any way to do this ?

Thanks Yair for the reply!
I have used property file only.
The thing is the property file is open and if someone edit it and restart the
java process he would be able to see all the DEBUG logs (which contains some
critical information)
I dont want this to happen so want to change at runtime (in code) the
configuration!

Why not use a regular property file?
Then when you to update the file you can load the changes automatically
using the "PropertyConfigurator.configureAndWatch" mechanism.
