Não consigo inicializar a aplicação loja. Pelo apt-get apenas consegui instalar o tomcat9, e a versão do mysql não pedia a senha inicial. Alterei a senha do root através do comando dentro do mysql, criei o banco de dados projeto_jpa, criei o arquivo setenv.sh conforme orientado e ainda assim não é feita a conexão.
Abaixo alguns trechos do log de erro:
