help???? Missing message for key "index.titl

[nothl]

I don't understand how could this possiblely happened.

here is what i have on my struts-config.xml
   <message-resources 
parameter="org.apache.struts.webapp.example.ApplicationResources"/>
   <message-resources 
parameter="org.apache.struts.webapp.example.AlternateApplicationResources" 
key="alternate">
   </message-resources>
   <message-resources parameter="com.emeta.web.WebResources" key="web">
   </message-resources>   
I am 100% sure that ApplicationResources.properties and other files are 
resited on the right folders. What can possibly goes wrong,
my web app starts find but i can't see why struts couldn't load these 
files, anybody knows why, thanks
