Erro após instalar o driver mysql - Aula 3 , Atividade 7 - Criando o Datasource

Referente ao curso EJB com Jakarta EE: API Rest com o servidor WildFly, no capítulo Persistência com JPA e atividade Criando o Datasource

Após realizar os códigos no prompt de comando para instalar o driver, surgiu a mensagem {"outcome => "success"}. Na vídeo aula, no minuto 7:52 do vídeo Atividade 7 - Criando o Datasource da Aula 3 , o professor digita no navegador: "localhost:8080" e em seguida abre a página do Wildfly. Fiz isso e funcionou. Porém quando eu cliquei no link: Administration Console, a página apresentou o seguinte texto: "Welcome to WildFly Your WildFly Application Server is running. However you have not yet added any users to be able to access the admin console.

To add a new user execute the add-user.bat script within the bin folder of your WildFly installation and enter the requested information.

By default the realm name used by WildFly is "ManagementRealm" this is already selected by default.

After you have added the user follow this link to Try Again."

e o endereço mostrado na barra de endereço do navegador foi: "http://localhost:9990/error/index_win.html".

Estou no aguardo de uma solução para que eu possa continuar o curso.

Grato.

Ivo, bom dia. Você precisa configurar o usuário para acessar a console do servidor. Criamos um tutorial nesta seção aqui: https://cursos.alura.com.br/course/ejb-jakarta-ee-api-rest-wildfly/task/81584 com este passo a passo você conseguirá incluir o seu usuário e prosseguir com as aulas =)

Olá, João. Deu certo. Eu pulei essa etapa pensando que fosse exatamente igual a do vídeo. Desculpe pelo vacilo.

Agora tenho outro problema lá na configuração do Datasource. Fiz todas as etapas acompanhando as suas explicações no vídeo e ao clicar no botão Test Conection apareceu a seguinte mensagem de erro:

17:39:36,941 ERROR [org.jboss.as.controller.management-operation] (External Management Request Threads -- 1) WFLYCTL0013: Operation ("test-connection-in-pool") failed - address: ([ ("subsystem" => "datasources"), ("data-source" => "AgendamentoEmailDS") ]) - failure description: "WFLYJCA0040: failed to invoke operation: WFLYJCA0047: Connection is not valid" 17:39:36,943 INFO [org.jboss.as.controller] (External Management Request Threads -- 1) WFLYCTL0183: Service status report WFLYCTL0186: Services which failed to start: service jboss.deployment.unit."agendamento-email-0.0.1-SNAPSHOT.war".INSTALL: WFLYSRV0153: Failed to process phase INSTALL of deployment "agendamento-email-0.0.1-SNAPSHOT.war"

Eu voltei e refiz tudo novamente, mas continua apresentando o mesmo erro.

Aguardo resposta. Grato.

Olá, Ivo. Bom dia. Quando você sobe sua aplicação, aparece algum erro na console? Ou só esse erro quando você tenta testar a conexão?

por Ivo Leonardo da Silva Costa

Olá, João. Agradeço por retornar.

Esse erro eu copiei do console.

Ivo. Mas o erro ocasiona no momento em que você sobe a aplicação ou só no momento de realizar o teste da conexão?

por Ivo Leonardo da Silva Costa
| 150.5k xp | 49 posts

Ah, sim. Esse erro no momento de realizar o teste de conexão.

Legal. O driver do mysql foi instalado né? Você pode me informar as suas configurações do datasource?

por Ivo Leonardo da Silva Costa

Descupe-me, João. Seria no arquivo standalone-full.xml? Esse:

Ivo, boa noite. Com essas informações do datasource você consegue acessar o seu mysql local sem problemas?

por Ivo Leonardo da Silva Costa
| 150.5k xp | 49 posts

Não entendi a pergunta. O nome do usuário e a senha estão corretos. Acesso com eles. Você se refere a isso?

solução!

Isso. A database que você configurou no datasource é a mesma que você tem no seu mysql? O usuário e senha também né?

por Ivo Leonardo da Silva Costa
| 150.5k xp | 49 posts

Olá, João. A database, usuário e senha são esses mesmos que estão no datasource. Já conferi e estão digitados certo.

Eu marquei sem querer o teu comentário como solucionado.

Você pode me informar em qual diretório está salvo o seu persistence.xml?

por Ivo Leonardo da Silva Costa
| 150.5k xp | 49 posts

Olá João. Não encontrei o persistence.xml. Em qual momento eu deveria tê-lo criado? Repassei os vídeos e não vi nada sobre o persistence.xml.

Ivo, boa tarde. No vídeo "Criando Datasource", a partir dos 11 minutos, nós criamos o arquivo persistence.xml.

por Ivo Leonardo da Silva Costa
| 150.5k xp | 49 posts

Ok. Acabei de conferir. O problema é que o erro está antes da criação do persistence.xml

Esse meu erro aparece no Test Connection lá no minuto 10:19. Agora eu fiz o persistence.xml mas apresenta erro no console após iniciar o servidor.

Aparece o mesmo erro ao iniciar o servidor?

Ivo, boa noite. Importei a sua aplicação aqui e configurei o datasource novamente. Em connection / Connection URL eu inseri: jdbc:mysql://localhost:3306/agendamentoemaildb?useTimezone=true&serverTimezone=UTC

Fiz o teste de conexão e funcionou 100%. Pode testar dessa maneira?

Agradeço pela ajuda e paciência, João. Vou dar uma pausa nesse curso e depois recomeço. Minha paciência chegou no limite. Já reiniciei o projeto umas 3 vezes incluindo a instalação do Wildfly. Quando eu estiver mais tranquilo eu recomeço. Vou estudar outra coisa. Grato.
