Hi Jim,

Fellow user here.

I am guessing that you need to migrate your application to Java 17+ and make 
all the necessary changes to move from the javax.* to the Jakarta EE jakarta.* 
packages.  This includes all servlet stuff.

Cheers, Jeff

Hi,

I was working on a web application about 2 years ago and I am finally getting 
back to my work on this application. However, when I try to bring up the app as 
a web page in firefox, tomcat is failing with a stack trace which I am 
attaching to this email.

Looking at the stack trace, I see that the class:
     javax.servlet.jsp.tagext.TagLibraryValidator
was not found.

My questions is: Where is the TagLibraryValidator class to be found?
