I am using Tomcat 5.5.15 on Window 2000 server. My web app worked well before reinstallation of Window2000. After reinstallation, I set up the same java environment with the same tomcat version. But a problem comes in the deployment of my former well-working app.
In the tomcat log, I got the following message:
2006-2-14 15:57:47 org.apache.catalina.startup.HostConfig deployDescriptor

It is really strange since I didn't change any codes in my web app including web.xml under WEB-INF. It worked well before the reinstallation, but fail to deploy after the reinstallation. What is the possible wrong?
My web.xml is attached. Thanks for any suggestions.
