java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagLibraryValidator

by

I had a similar problem, I am using Tomcat 10. I was getting this error using Apache NetBeans 12.3 IDE.

I added the following libraries:

  1. jakarta.servlet.jsp.jstl-api-2.0.0.jar
  2. jakarta.servlet.jsp.jstl-2.0.0 (1).jar

My code is running fine now.
link to see where I added them
