com.sun.enterprise.config.ConfigException: Error refreshing ConfigContext

My controller testcases are passed but still console shows the following exception. As far I researched in google, I get to know that this exception might because of tags not closed in dispatcher servlet xml file. But all the tags in my Dispatcher servlet are closed correctly. Any Idea? Thanks in advance.
