Tomcat Application throws java.lang.ClassNotFoundException for Jar in WEB-INF/lib

I'm trying to add Boilerpipe to do web scraping with my Tomcat project, but when I do so I tend to run into a problem. I add the jar as well as the necessary resources (nekohtml-1.9.13.jar and xerces-2.9.1.jar) to my Web-INF/lib folder and as an external library in the project structure.

However, every time I try to deploy the application, I get a java.io.ClassNotFoundException while building from Tomcat and I have no idea why. Specifically, Tomcat tells me that access is denied, but I have no idea what that could mean since it is easily accessing other Jars in the same folder.

Here is the full stacktrace of the Tomcat error

I also read somwhere that duplicating Tomcat's existing libaries in the WEB-INF/lib folder is bad, but I am not sure if I did that. Here is what I have in my lib folder:
(most of it was auto-imported by IntelliJ)

javax.annotation.jar
javax.ejb.jar
javax.jms.jar
javax.persistence.jar
javax.resource.jar
javax.servlet.jar
javax.servlet.jsp.jar
javax.servlet.jsp.jstl.jar
javax.transaction.jar
joda-time-2.10.5.jar
jstl-1.2.jar
mysql-connector-java-5.1.48-bin.jar
taglibs-standard-jstlel-1.2.5.jar

Any help would be greatly appreciated.

Thanks.
