Configuring log4j with soap & tomcat

[Ram, Kumar]

Hi,
        I am trying to configure log4j with soap & tomcat. I have placed the
log4j.xml file in the webapps directory of my soap installation
C:\soap-2.1\webapps. 
I have tomcat installed in C:\jakarta-tomcat-3.2.1. I finished the
deployment etc. And the
service works fine and gives me actual results. However i keep getting an
error to
check the log4j configuration.

log4j:ERROR No appenders could be found for category
(samples.test.UserCheckSamp
le).
log4j:ERROR Please initialize the log4j system properly.

The following is the contents of my log4j.xml files.
