Erro HTTP Status 500 - java.lang.NoSuchMethodError: org.jboss.logging.Logger.debugf(Ljava/lang/String;I)V

Oi Matheus, tudo bem?

Consegue subir seu projeto no dropbox ou github ou algum outro lugar que preferir e me mandar o link para que eu possa verificar?

Abraços!

Opa, tudo bom.

Criei uma conta e um repositório no github, segue o link.

https://github.com/matheusgomide21/Alura-horas

Ainda acostumando com a ferramenta.

Oi Matheus!

eu precisaria do seu projeto de código (pom.xml, arquivos .java...). Com o arquivo .war eu não consigo analisar.

pode subir o código? zipar a pasta do projeto serve também.

Fico aguardando, e qualquer dúvida é só avisar aqui. :-)

Desculpe o leiguismo Lucas, coloquei o arquivo .rar no projeto, só acessar o link.

https://github.com/matheusgomide21/Alura-horas

Oi Matheus,

que isso, sem problemas. e qualquer dúvida, pode sempre perguntar no fórum. ;)

Bem, como você falou, parece ser algum conflito de biblioteca mesmo. No caso a biblioteca jboss-logging.

Além de fazer uma exclusion no weld-core-impl fiz também no weld-servlet-core, que também possui um jar do jboss-logging, com uma versão mais antiga do que a que o hibernate do seu projeto possui.

<dependency>
    <groupId>org.jboss.weld.servlet</groupId>
    <artifactId>weld-servlet-core</artifactId>

Testa e vê se funciona? Fico aguardando.

Abraços!

Tentei excluir as dependências e depois apareceu o seguinte erro:

Vou postar a stacktrace:

Olhando a stacktrace vi isso:

INFO: Tomcat 7+ detected, CDI injection will be available in Servlets and Filters. Injection into Listeners is not supported

Será que atrapalha em alguma coisa?

Oi Matheus, desculpe pela demora.

eu testei aqui e recebi o mesmo erro. voltei pra versão 7 do Tomcat no plugin, e recebi um outro erro, mas dessa vez do Driver do MySQL.

É relacionado a Timezone, mas não faço ideia o por que desse erro. Eu resolvi utilizando uma outra versão do Driver.

Então funcionou. Testei e inseriu um usuário no banco através do form. Então, fiz o seguinte:

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <configuration>
        <path>/</path>
    </configuration>
</plugin>

E no driver do MySQL (só mudou a versão):

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.41</version>
</dependency>

O pom.xml completo aqui:

https://gist.github.com/lucas-felix/913d204734ca40ca6d46d379914a5d00

Testa e avisa no que deu?

Opa, tudo bem cara domingão ninguém é de ferro.

Sinceramente achei que hoje não teria uma resposta por ser feriado, mas enfim...

Fiz o que recomendou, troquei o tomcat e a versão do sql connector e deu erro, vou postar a stacktrace.

Bom dia, Matheus!

eu consegui reproduzir esse erro ao rodar o plugin do tomcat do maven, é assim que você está rodando seu projeto?

Minha sugestão é baixar o Tomcat 7, adicionar no Eclipse e tentar executar o projeto, similar ao que é feito no curso.

Você pode baixar o Tomcat 7 aqui:

https://tomcat.apache.org/download-70.cgi

Pode testar dessa forma? Qualquer dúvida nesse processo é só avisar aqui.

Abraço!

Boa tarde.

Baixei o tomcat, testei da maneira que pediu e deu erro.

Vou postar a stacktrace.

Percebi também que olhando as facets do projeto aparecem 2 avisos:

• implementation of project facet jst.cdi could not be found. Funcionality will be limited -

• implementation of project facet jboss.m2 could not be found. Funcionality will be limited -

Não sei se interfere em alguma coisa, aparentemente sim.

Testando aqui reparei que o erro em si estava no provider. A vídeo aula dizia para usar o seguinte provider:

• org.hibernate.ejb.HibernatePersistence

Então eu lembrei que o provider do curso de hibernate e jpa era esse:

• org.hibernate.jpa.HibernatePersistenceProvider

Troquei, e a aplicação funcionou.

Pode me dizer se há alguma configuração que posso fazer para utilizar o provider do ejb ou se esse mesmo vai servir sem nenhum bug?

Meu persistence ficou assim:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

        <!-- Aqui são listadas todas as entidades -->
        <class>br.com.alura.horas.modelos.Usuario</class>

        </properties>
    </persistence-unit>
</persistence>

Atenciosamente.

Oi Matheus! Bem lembrado, acabei esquecendo de dizer que troquei o provider aqui. :(

Que bom que funcionou!

Pode utilizar este mesmo, deve funcionar sem maiores problemas. Caso aconteça algo, pode abrir um novo tópico, tá bem?

Abraço
