TomEE + EclipseLink:EntityManager de inyección no funciona

Question

Estoy tratando de conseguir este JPA + EJB + Facelets ejemplo se ejecuta en TomEE Perfil Web.Debido a que la muestra utiliza EclipseLink, he descargado EclipseLink y copiado eclipselink/jlib/eclipselink.jar en el TomEE/lib directorio.

Pregunta 1: Es este el único archivo que necesita copiar?

Tengo un número de Entity clases de JSF SessionScoped ManagedBean para servir las peticiones web, un Estado de EJB para manejar solicitudes de base de datos, y uno de los más EJB que carga los datos en la base de datos en start-up.

Los fragmentos de código de la ManagedBean y el Estado de EJB son las siguientes:

@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());
        }
    }
}

Cuando la línea de em.persist(part); en RequestBean intenta ejecutar, me sale el siguiente excepción:

Como no estoy muy familiarizado con la magia que es Java EE no tengo casi ni idea de lo que está mal aquí, pero me encantaría saber cuál es la causa de la primera línea en la traza de la pila, por encima de:

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

Pregunta 2: Por alguna razón la inyección de la Gerente de la Entidad no parece estar funcionando.Alguien tiene alguna idea de por qué?

La integridad, la de abajo es mi persistence.xml, que es en la project/src/main/webapp/classes/META-INF/ directorio:

<?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 Fuente

En caso de que alguien quiera ver la estructura de directorios de código fuente, archivos de configuración, etc.el proyecto, he subido a github aquí.

Answer 1

Actualizado persistence.xml el uso de OpenJPA, de acuerdo a Común PersistenceProvider propiedades:

<?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>

Todavía tengo la siguiente excepción:

Al parecer eso es un error conocido en TomEE 1.0.0 que se ha resuelto en el tronco, así que me descargar el último beta3 instantánea

Ahora todo corre bien.
