Tomcat refuses to deploy CSS files

Okay I am using Tomcat to deploy my Web-App. The files in /WebContent Directory are-:

chat.html
chat.js
chat.css

and a few .jpg files.

Now when I deploy the application through eclipse all the files are deployed except

chat.css

It is not present in the wtwebapps directory of Tomcat. Why is that ?

Also I can't serve any new files. For example if I put a file called a.js in my WebContent folder it is also not deployed.

What am I doing wrong ?
