Hello all,

I am developing Report Application Form using Struts.I have set everything right, web.xml,struts-config.xml,struts-validation.xml.But the application is giving problem while displaying the empty item (should output validation errors).

Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

java.lang.IllegalArgumentException: Resources cannot be null.
at org.apache.commons.validator.Validator.(Validator.java:188)
