TeamCity .war doesn't start

I cannot start the war file for TeamCity-1.0.
I am using Windows XP and Tomcat 5.5.17 as a windows service.
The error I get is

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

I have searched already on the forum and someone else has mentioned adding
-Dteamcity_logs=C:\Program Files\Apache Software Foundation\Tomcat 5.5\logs
to the start up of the service, but this has made no difference. Can someone advise me what to do?
