Hallo Leute,

ich bin ein Newbie in Sachen Java und Hibernate bzw. MysqlDB.

Ich habe bisher meinen JBoss AS7 via standalone.xml konfiguriert:

[CODE]       <subsystem xmlns="urn:jboss:domain:datasources:1.0">

            <datasources>

                <datasource jta="true" jndi-name="java:jboss/datasources/rbowDB" pool-name="rbowDB" enabled="true" use-java-context="true" use-ccm="true">

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

                    <driver>mysql-connector-java-5.1.26-bin.jar</driver>

                    <pool>

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

                        <prefill>true</prefill>

                        <use-strict-min>false</use-strict-min>

                        <flush-strategy>FailingConnectionOnly</flush-strategy>

                    </pool>

                    <security>

                        <user-name>dbuser</user-name>

                        <password>dbuser1</password>

                    </security>

                </datasource>

                <drivers>

                    <driver name="mysql-connector-java-5.1.26-bin.jar" module="com.mysql">

                        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>

                    </driver>

                </drivers>

            </datasources>[/CODE]

Desweiteren habe ich dann in meinem Eclipse-Projekt die persistence.xml wie folgt konfiguriert:

[CODE]<?xml version="1.0" encoding="UTF-8"?>

<!-- Hier wird die zum JBoss zugehörige Datenbank angesprochen JBoss-Konfiguration der DB im Verzeichnis /standalone/configuration/standalone.xml -->

<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="primary">

      <jta-data-source>java:jboss/datasources/rbow.rbowwebappDS</jta-data-source>

      <properties>

         <!-- Properties for Hibernate -->

         <property name="hibernate.hbm2ddl.auto" value="create-drop" />

         <property name="hibernate.show_sql" value="false" />

      </properties>

   </persistence-unit>

</persistence>[/CODE]

und jetzt würde ich gerne innerhalb eines Unittest mal eine Entität persisiteren um die Konfiguration zu testen.

[CODE]package end2end;

import javax.persistence.EntityManager;

import javax.persistence.EntityManagerFactory;

import javax.persistence.Persistence;

import org.junit.Test;

import model.Aktion;

import model.Konto;

public class TestPersistence {

    private Aktion aktion = new Aktion();

    @Test

    public void testPersist() {

       

        String persistenceUnitName = "primary";

        EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory(persistenceUnitName);

       

        EntityManager entityManager = entityManagerFactory.createEntityManager();

        entityManager.getTransaction().begin();

        fillAktion(aktion);

        entityManager.persist( aktion);

        entityManager.getTransaction().commit();

        entityManager.close();

    }

   

    private void fillAktion(Aktion aktion) {

        aktion.setId(1l);

        aktion.setKonto(new Konto("Max Mustermann", "Bank", "1234", "100200300"));

        aktion.setName("Max Mustermann");

    }

}[/CODE]

Was genau ist denn jetzt für den Unit-Test der String persistenceUnitName zu nehmen?

Mache ich das so richtig, oder muss ich was anders tun?

Die Fehlermeldung die ich bekomme ist jedenfalls:

[CODE]javax.persistence.PersistenceException: No Persistence provider for EntityManager named primary
