Erro ao inciar projeto.

Opa Dayson, o arquivo persistence.xml está na dentro da pasta src/META-INF ?

Olá, verifiquei e não tinha colocado o nome do datasource, ao colocar apresentou outro erro.

Oi Dayson,

A exception indica que não existe a classe => br.com.caelum.livraria.modelo.Autor. O pacote é esse mesmo?

Sim. só importei o projeto da aula 1 e não consigo colocar ele para rodar.

Olá,

Só importou o projeto no Eclipse, né ?!

Configurou o datasource livrariads no Wildfly ? O nome do datasource no persistence.xml e na configuração do Wildfly devem ser iguais.

Olá, conforme a vídeo aula 3, adicionei as tags e dentro do standlone.xml do jboss AS. criei 2 pastas dentro no servidor Jboss : modules/com/mysql/main e coloquei 2 arquivos dentro desta pasta: module.xml e o jar do mysql.

Olá,

Como disse anteriormente, no standalone.xml, o nome do datasource é "java:/livrariads" mas no persistence.xml o nome do datasource é "livrariads" somente. Devem ser iguais.

Olá está assim meu persistence.xml

<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
        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">

    <persistence-unit name="livrariads">

        <provider>org.hibernate.ejb.HibernatePersistence</provider>

        <!-- acessando um DataSource que é livrariaDS -->
        <jta-data-source>java:/livrariaDS</jta-data-source> 

        <class>br.com.caelum.livraria.modelo.Autor</class>
        <class>br.com.caelum.livraria.modelo.Livro</class>
        <class>br.com.caelum.livraria.modelo.Usuario</class>

        <properties>

            <!-- Configuracoes especificas do Hibernate -->
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="true" />

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

Olá,

O nome do datasource é case-sensitive, faz a distinção de maiúsculas e minúsculas. Assim no standalone.xml o nome do datasource deve ser: "java:/livrariaDS" também.

Opa, obrigado pela ajuda. está assim meu código. creio que está correto.

standlone.xml

<datasource jndi-name="java:/livrariaDS" pool-name="livrariaDS"
                    enabled="true" use-java-context="true">

                    <connection-url>jdbc:mysql://localhost:3306/livraria</connection-url>

                        <max-pool-size>100</max-pool-size>
                        <prefill>true</prefill>
                    </pool>

                    </security>
                </datasource>
<drivers>

                    <!-- Driver Mysql. -->
                    <driver name="com.mysql" module="com.mysql">
                    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                    </driver>
</drivers>
