Migrando do Tomcat 7 para o 10

Programação Java
#1

Olá a todos
Tenho aplicações rodando em Tomcat 7 e funcionam sem problemas. Estou me preparando para migrar para o tomcat 10 porque o novo servidor exige e não consigo startar a aplicação mais simples que eu tenho.

Desde já agradeço a ajuda

Este é o console:

A partir da versão 10 do tomcat, o projeto sofreu algumas mudanças devido à migração para o projeto jakarta. Com isso, parece que alguns pacotes tiveram seus nomes alterados. Sem precisar fazer grandes alterações nos seus projetos, vc pode usar a versão 9 do tomcat.

Na página inicial do tomcat tem isso:

Users of Tomcat 10 onwards should be aware that, as a result of the move from Java EE to Jakarta EE as part of the transfer of Java EE to the Eclipse Foundation, the primary package for all implemented APIs has changed from javax.* to jakarta.* .

Obrigado Lucas_Camara, estávamos mesmo na dúvida se íamos direto pro 10 porque fizemos antes testes com o 9 e fomos bem sucedidos.

Essa mudança no tomcat 10 apresenta muitas vantagens em relação ao 9?
