<bean:message tag displays as ???en_US.lbl..

Hello, I'm converting Struts application that is running on WL8.1 to WL 10.1. The application is using bean:message to populate some info on the page. It is working fine in WL 8.1 as well as working fine on my local in WL10.1 but when the app gets deployed to the UNIX box the bean:message tag is not been recognized and the message gets displayed as ???en_US.lbl.PolNo???.. Please help...Thank you

Looks like some resource files aren't being picked up--have you verified correct deployment?

well i thought I triple check it

.... Here is my set up:
in struts-config.xml i have <message-resources parameter="com.thehartford.ild.idw.struts.resources.ApplicationResources" null="false" />
in my jsp i have <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %> as well as <bean:message key="lbl.Bob.PolNo"/>. The interesting thing about it is that I have same set up for other tlds and those are working fine, for example <%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>... Thank you
