ClassNotFoundException for JSP while upgrading to Tomcat 8

[Doug Elder]

I'm upgrading from Tomcat 6 to Tomcat 8. I have a legacy app that works on Tomcat 6 but will not work on Tomcat 8. The error message I'm getting is in red. I'm fairly new and didn't configure this app only enhanced it. There is an index.jsp page in the app.

SEVERE: Servlet.service() for servlet [jsp] in context with path [/forecast] threw exception [java.lang.ClassNotFoundException: org.apache.jsp.login_jsp] with root cause
java.lang.ClassNotFoundException: org.apache.jsp.login_jsp

The exception states that it's not able to load the servlet class which was compiled by the container for the JSP. That's a bit weird. What does your login.jsp look like and what version and vendor of Java runtime are you using to run Tomcat 8?

I'm using jre7 from oracle. My login.jsp doesn't look terribly different than any of my login.jsp pages. My login.jsp looks like this:
