CAS 4.0.1 Theme 'theme': No message found

[Vibhatha Abeykoon]

I am using cas server 4.0.1 version and I am getting the following error when I tried to access this url

https://localhost:9443/cas/login

org.springframework.context.ApplicationContextException: Unable to initialize application context.
        org.jasig.cas.web.init.SafeDispatcherServlet.service(SafeDispatcherServlet.java:127)

This is what comes in the browser.

In the tomcat server console the following error message is coming...
