How to initialize the log4j system properly?

Question

I tried to run sample examples for hibernate and spring but both the time I got below error.

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). log4j:WARN Please initialize the log4j system properly.

I searched over net and added sample log4j file but still problem exists. Could you please help me to resolve my problem as I am quite new to this.
