I have a web app that has been running fine for many years. I tried

Without changing anything, this app works fine with Tomcat:
9.0.43
8.5.63
8.0.27
But I get the above error with Tomcat 10.0.2 only.
Sure appreciate any help.
Did you read the Migration Guide? Tomcat 10 is built with and requires
the use of all the Jakarta EE package names. javax.servlet is dead. Long
live jakarta.servlet!
http://tomcat.apache.org/migration-10.html#Specification_APIs
You might want to have a look at the migration tool:
https://tomcat.apache.org/download-migration.cgi
Not a huge amount of documentation about it, so you'll have to piece
things together yourself.
Hope that helps,
