Hey Chris,

Thanks a lot for the detailed reply. At the moment, I have written a class
that extends AccessLogValve.java.
I deactivated the AccessLogValve from the server.xml and <Valve
className="my.Valve"> element to your <Engine> for this new Extended
Valve.(We wanted it at Engine level.)
Works completely fine!

Thanks for the clarification :) Its just that I had no idea about this
component when I started the internship.
Since I dont have a lot of time, I prefered to get some help on this
list.(Which I got! More than Enough actually)

I thank you and Chuck for that. hats off! honestly.
I just needed to create a simple Valve and see how to deploy it. (Like a
prototype to test what can be possible if we use the Valve component.)It was
pretty easy once I actually understood how to do it. Now I just need to call
an event and mount this "monitored info"

Thanks once again,

S
