Problemas com ao acessar os menu Usuario

Olá!

Ref. ao Curso VRaptor e JPA: Pratique Java com um sistema completo... Estou com problemas no acesso de menu para gravar usuário. Ao acessá-lo é apresentado:

...................................

HTTP Status 500 - WELD-001435: Normal scoped bean class br.com.alura.horas.controllers.UsuarioController is not proxyable because it has no no-args constructor - .

type Exception report

message WELD-001435: Normal scoped bean class br.com.alura.horas.controllers.UsuarioController is not proxyable because it has no no-args constructor - .

description The server encountered an internal error that prevented it from fulfilling this request.

...................................

...Então tentei logar na aplicação, mas ao clicar no botão autenticar apareceu a mensagem:

...................................

HTTP Status 500 - javax.persistence.PersistenceException: Unable to locate persistence units

type Exception report

message javax.persistence.PersistenceException: Unable to locate persistence units

description The server encountered an internal error that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: javax.persistence.PersistenceException: Unable to locate persistence units br.com.caelum.vraptor.VRaptor.doFilter(VRaptor.java:122) ...................................

...Então fui ver no banco de dados, e não de fato não existe a tabela de usuários. Não estou conseguindo fazer a aplicação criar a tabela, como é feito nos videos. O que pode ser?

Obs. e já terminei de implementar todo o código mostrado nas aulas.

desde já agradeço toda ajuda!

Opa, o primeiro problema é justamente o que fala na exception, sua classe não tem um construtor sem argumentos. Você precisa deixar um lá, o CDI exige.

Em relação ao segundo, parece que você não colocou o persistence.xml dentro da pasta src/META-INF ou src/main/resources/META-INF, caso esteja usando maven.

Olá!

Para a parte acesso do menu do usuário, coloquei o construtor sem argumentos e deu certo (=D) valeu!!!

Mas para o autenticar ainda não, conferi o caminho do persistence.xml e ele está no caminho que você colocou, Mas ao clicar no botão autencia, continua dizendo que não o encontra. (=X) o que mais pode ser?

Continuo sem conseguir utilizar a aplicação como é mostrado nas video-aulas.

Opa, se o persitence ta lá, sobra a opção de o nome da persistence-unit não ser o mesmo que vc ta usando dentro da aplicação. Confere? Ta usando tudo na mão, ou através de um plugin do vraptor?

Oi Alberto!

estou usando o arquivo na mão, e conferindo havia erros de digitação.... resolveu aquele erro...

mas apareceu outro, dessa vez no EntityManagerProducer, então ajustei ele porque tbm estava com espaçamento pelo TAB e colocando pelo SPACE parece que funcionou, pois a mensagem de erro mudou.

Estou estranhando que está dando erro quando utilizo o botão TAB pra dar o espaçamento, é exigido que o espaçamento seja feito somente com o botão SPACE?

Agora apareceu essa mensagem:

.........................

HTTP Status 500 - java.lang.ExceptionInInitializerError

exception

javax.servlet.ServletException: java.lang.ExceptionInInitializerError br.com.caelum.vraptor.VRaptor.doFilter(VRaptor.java:122) ......................... como eu faço pra corrigir? obs. tem um arquivo persistence.xml em "JPA Content"

Opa, o pior é que vc colocou só parte da exception, aí não da para ajudar muito agora. Copia a stacktrace inteira e cola aqui, ok? Tenta usar também o botão inserir código, para que ele fique formatado. Você pode conferir no campo de texto ao lado se está ficando formatado.

Olá Alberto! Segue a log, Acho que formato certo agora:

Olá Alberto!

na aula 1, no item de Preparando ambiente... estava da forma abaixo:

então alterei para

<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/alura_horas" />

conforme vc falou...e funcionou ! valeu!!! e criou as tabelas certinho!

... ai mudou para um erro de que não encontrava o usuario dentro da tabela... fui e criei ela manualmente um usuario no banco de dados (fiquei bloqueado, porque é feito uma validação/autenticação do cadastro, sendo que ele ainda não tinha sido feito)...

mas agora apareceu mais um erro e não não estou conseguindo resolver:

HTTP Status 500 - java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: usuario is not mapped [select u from usuario u where u.login = :login and u.senha = :senha]

Você fez a query do hibernate apontando para usuario e, como a exception está informando, ele está dizendo que não consegue achar essa classe. O nome da classe não é Usuario? É super importante que vc leia a exception e tente resolver, dessa forma o aprendizado fica mais fixado.
