Montar o ambiente para utilizar o MySQL

Utilizando a ideia do banco somente como um objeto estava normal, porém a montagem do ambiente para utilizar o MySQL não deu certo. Inseri o servidor Wildfly 16 e ao iniciar o servidor com as configurações propostas na seção, aparece os seguintes erros:

O que falta para poder montar o ambiente para continuar as aulas?

Na versão 8.x do MySql, o nome da classe que implementa java.sql.Driver no MySQL Connector / J foi alterado de com.mysql.jdbc.Driver para com.mysql.cj.jdbc.Driver . O nome da classe antiga foi descontinuado.

O wildfly também tem algumas configurações diferentes do JBoss 7.1 mostrado no curso.

solução

Modifiquei o driver no standalone.xml para:

<driver name="mysql" module="com.mysql">
    <driver-class>com.mysql.cj.jdbc.Driver</driver-class>
    <xa-datasource-class>com.mysql.cj.jdbc.MysqlXADataSource</xa-datasource-class>
</driver>

Após isso, mudei a tag driver no datasource para mysql. Adicionei um módulo no module.xml:

<module name="javax.transaction.api"/>

Dessa forma, deu certo para o driver mysql-connector-java-8.0.16-bin usando wildfly.
