Exercicio não funciona no Wildfly!! Me ajudem.

Oi Thiago, é alguma besteira.

O seu projeto está configurado corretamente e está compilando (nao tem nenhum error na view Problems)

Quando vc sobe o Wildfly aparece algum erro?

abs

Não.A página sobe normalmente. O erro é emitido apenas quando eu clico no botão gravar. Já não sei mais o que fazer.

Tenta uma vez usar @Names em vez de @ManagedBean.

Também, a El correta é action="#{produtoBean.gravar}"

abs

@Names não importou nada. Tentei @Named e também não funcionou. O erro persiste.

segue o web.xml: ?xml version="1.0"?>

Oi Thiago,

vc tem algum JAR no seu projeto web (não deveria)?

abs

Não entendi. Tenho as libs. Você pode disponibilizar esse exemplo funcionado?

Então o Wildfly já tem os libs do jsf, jpa e cdi embutido. Provável que isso esteja dando problemas.

Eu explique isso no 3 modulo sobre JSF e mostro como usar JSF com CDI ou Spring no Tomcat e Wildfly:

https://cursos.alura.com.br/course/jsf-cdi

No curso também tem o download do projeto, mas vc precisa configurar mais coisas no wildfly, por exemplo o datasource.

abs

Thiago, não é melhor fazer o curso com a infra que o instrutor indica, depois de terminar, tentar migrar para o servidor de aplicação? Digo isso porque você pode esfriar e ficar batendo cabeça com coisa de infraestrutura quando podia estar já avançando no curso. É só uma sugestão. Aliás, como Nico disse, em outro módulo ele usa o wildfly. Quem sabe migrar par ao wildfly nesse módulo seria o ponto perfeito.

Oi Thiago,

nao sei exatamente o seu motivo de usar Wildfly, mas vai devagar :) Um servidor de aplicação é algo complexo. No caso dessa aplicação, todas as bibliotecas são fornecidas pelo wildfly mas as configurações dentro da app precisam estar corretas.

Eu aconselho assisti primeiro todos os modulos sobre JSF, e depois o treinamento EJB. Isso vai te dar uma boa base para se dar bem com Wildfly.

abs

Boa tarde Thiago,

Pelo que eu vi você está chamando #{produtoBean.Gravar()} quando o seu método é gravar() em minusculo. Ele falou que não encontrou aquele método em especifico.

Se caso houver a troca do nome e o erro persistir tente desinstalar o wildfly e instalar novamente usando o eclipse. Mas creio que o erro é a chamada do método não existente.

Abraço! :D

Boa tarde Gleidson,

Sim. Eu já realizei essa alteração, mas o erro persiste. Eu já fiz aulas, entretanto quero realizar os exercícios do "zero" e não pegar apenas os.zips das aulas.

Oi Thiago,

vc já configurou o datasource?

abs

Não porquê eu ainda não estou realizando a persistência.

Blz, agora apague todos os seu JARs da pasta WEB-INF/lib, menos o JAR do Primefaces.

Além disso, você deve adicionar o Server Runtime do Wildfly no seu projeto. Isso também deveria resolver o problema porque o @Named não foi encontrado.

Se o projeto compila corretamente, tente subir o Wildfly novamente.
