Hi There,

I am having a problem with my application. When I develop the application
to one of the test server, I got the following error. But I also tested on
three other servers. It worked fine. Any one know what it is wrong? Is the
log4j set up at the tomcat server wrong? and where is it wrong if know?

many thanks
