HTTP Status 500 – Internal Server Error | Java e JPA: Otimizações com JPA2 e Hibernate

Olá, estou tendo problema ao acessar a parte de edição dos produtos, sempre que clico em editar me vem um erro, estou usando o mysql 8.0:

GRAVE: Servlet.service() for servlet [dispatcher] in context with path [/projeto-jpa-2] threw exception [org.apache.jasper.JasperException: java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.views.produto.form_jsp] with root cause

GRAVE: Servlet.service() for servlet [jsp] threw exception
java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.views.produto.form_jsp
