Hi,
The SessionLog uses SLF4J which is a logging facade for various logging
APIs (similar to Commons Logging). You probably have slf4j-nop.jar in
your class path, right? In that case nothing will be logged. If you
replace it with slf4j-simple.jar log messages with level INFO and higher
will be logged to the console. If you want to use log4j you should use
either slf4j-log4j12.jar or slf4j-log4j13.jar and then you just set up
log4j as usual.
You will find all these jars through the SLF4J home page as well as the
manual: http://www.slf4j.org

Thanks Niklas. You are such wonderful. It works perfectly now.

Add something like that before you do anything else in main() and it

As another option, I place the log4j.properties file in the src directory in
Eclipse so that it gets loaded into the classpath. But of course either way
works...

FYI, I have tried replacing slf4j-log4j12-1.3.1.jar with
slf4j-simple.jar and
Logging works. :) Thanks.
However, it would very great if you can guide me on what is the error I
encounter when using the log4j as mentioned in previous mail.

Hi Niklas,
I actually included slf4j-log4j12-1.3.1.jar and log4j-1.3alpha-8.jar
in
my classpath.
I have also included a log4j.properties file ( see below ). When I run
it, it does
not produce any log messages. Do I need to add any code or bindings in
my
ClientSessionHandler?
======== log4j.properties file ========
log4j.rootLogger=debug, stdout, R
