Spring MVC -- java.lang.ClassCastException

Hopefully this will be the last question from this Spring MVC newbie. When I try to call the front page of my Spring 3.2 MVC web application on Tomcat 7.0, I get an HTTP Error 500 with the following errors in my console. Error in console: ``` SEVERE: Servlet.service() for servlet [jcbulboard] in context with path [/jcbulboard] threw exception [Unable to initialize TldLocationsCache:
