TomEE + EclipseLink:EntityManager injeção de não trabalhar

StackOverflow https://stackoverflow.com//questions/10693905

Pergunta

Eu estou tentando chegar a este JPA + EJB + Facelets exemplo execução em TomEE Perfil na internet.Porque o exemplo usa EclipseLink, eu baixei EclipseLink e copiado eclipselink/jlib/eclipselink.jar no TomEE/lib diretório.

Questão 1: Este é o único arquivo que eu precisa copiar?

Eu tenho um número de Entity classes, um JSF SessionScoped ManagedBean para servir solicitações da web, um com estado EJB para lidar com solicitações de banco de dados, e mais um EJB que carrega os dados para o banco de dados de start-up.

Snippets de código do ManagedBean e com estado EJB estão abaixo:

@Singleton
@Startup
public class ConfigBean {
    @EJB
    private RequestBean request;

    @PostConstruct
    public void createData() {
        request.createPart("1234-5678-01", 1, "ABC PART", new java.util.Date(),
                "PARTQWERTYUIOPASXDCFVGBHNJMKL", null);    
        // more code here...
    }
}

@Stateful
public class RequestBean {
    private static Logger logger = Logger.getLogger("order.ejb.RequestBean");
    @PersistenceContext
    private EntityManager em;

    public void createPart(String partNumber, int revision, String description,
            java.util.Date revisionDate, String specification,
            Serializable drawing) {
        try {
            Part part = new Part(partNumber, revision, description,
                    revisionDate, specification, drawing);
            em.persist(part); // <--- EXCEPTION THROWN HERE
        } catch (Exception ex) {
            throw new EJBException(ex.getMessage());
        }
    }
}

Quando a linha em.persist(part); em RequestBean tenta executar, eu recebo a seguinte exceção:

Como não estou muito familiarizado com a magia que é Java EE eu quase não têm idéia do que está acontecendo de errado aqui, mas eu adoraria saber o que está causando a primeira linha de rastreamento de pilha, acima:

WARNING: Injection: No such property 'order.ejb.RequestBean/em' in class order.ejb.RequestBean

Questão 2: Por algum motivo injeção de a Entidade gestora não parece estar funcionando.Alguém tem alguma idéia do porquê?

Para completar, abaixo está o meu persistence.xml, o que está no project/src/main/webapp/classes/META-INF/ diretório:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    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">
    <persistence-unit name="order" transaction-type="JTA">
        <jta-data-source>jdbc/__default</jta-data-source>
        <properties>
            <property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
            <property name="eclipselink.ddl-generation.output-mode"
                value="both" />
        </properties>
    </persistence-unit>
</persistence>

Código-Fonte

No caso de alguém quer ver a estrutura de diretório do código-fonte, arquivos de configuração, etc.do projeto, eu já carregou-o para github aqui.

Foi útil?

Solução

Atualizado persistence.xml para usar OpenJPA, de acordo com Comum PersistenceProvider propriedades:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    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">
    <persistence-unit name="order" transaction-type="JTA">
        <jta-data-source>jdbc/__default</jta-data-source>
        <properties>
            <property name="openjpa.jdbc.SynchronizeMappings"
                value="buildSchema(foreignKeys=true,schemaAction='dropDB,add')" />
            <property name="openjpa.jdbc.SchemaFactory" value="native(foreignKeys=true)" />
            <property name="openjpa.jdbc.MappingDefaults"
                value="ForeignKeyDeleteAction=restrict, JoinForeignKeyDeleteAction=restrict" />
            <property name="openjpa.Log" value="DefaultLevel=TRACE,SQL=TRACE" />
        </properties>
    </persistence-unit>
</persistence>

Ainda tenho a seguinte exceção:

Aparentemente, isso é um bug conhecido no TomEE 1.0.0 que foi resolvido no tronco, então eu baixei o mais recente beta3 instantâneo

Agora tudo corre bem.
