Dana, Please see the migration -guide (https://tomcat.apache.org/migration-10.html) here is a quote from it "
Apache Tomcat 10 supports the Jakarta Servlet 5.0, Jakarta Server Pages 3.0, Jakarta Expression Language 4.0, JakartaWebSocket 2.0 and Jakarta Authentication 2.0 specifications<https://cwiki.apache.org/confluence/display/TOMCAT/Specifications>. There is a significant breaking change between Tomcat 9.0.x and Tomcat 10.0.x. The Java package used by the specification APIs has changed from javax... to jakarta.... It will be necessary to recompile web applications against the new APIs. Alternatively, users can convert an existing WAR file from Java EE 8 to Jakarta EE 9 using the Apache Tomcat migration tool for Jakarta EE<https://tomcat.apache.org/download-migration.cgi>."
