Some of us have just given up on Windows entirely…

Not lately. I can’t recall when j2ee.jar was last useful, but I’m pretty sure 
it’s been well over a decade. You most likely need to delete it.

First, look at the Tomcat migration guides: 
https://tomcat.apache.org/migration.html

You’ll need to review each one, starting with the last version of Tomcat you 
were using, up to the one for 10.1. In particular, when Oracle gave control of 
the Java EE spec to Eclipse, the classes were renamed from javax to jakarta for 
legal reasons, so all code using the old class names must be updated to the 
revised ones. This can be done with a migration tool supplied by Tomcat:

https://tomcat.apache.org/download-migration.cgi

or by placing old apps in the webapps-javaee directory rather than webapps and 
letting Tomcat convert them automatically. Look at the documentation for the 
legacyAppBase attribute of the <Host> element:

https://tomcat.apache.org/tomcat-10.1-doc/config/host.html#Common_Attributes
