jndi connexion de base de données avec jpa et eclipselink

J'essaie de configurer une connexion de base de données en java avec JNDI en combinaison avec eclipseLink/JPA sur Tomcat 5.5. J'ai déjà configuré la ressource JNDI dans web.xml et context.xml.

La connexion db fonctionne avec JNDI sans utiliser JPA et eclipseLink.
Après la configuration de l'persistence.xml pour eclipseLink, je suis l'exception suivante.

Je ne sais pas comment configurer l'persistence.xml il est correct d'utiliser JNDI de la source de données pour la connexion db.

L'exception

Il suffit d'ajouter la classe JPAEclipseLinkSessionCustomizer à votre projet et à le configurer persistence.xml comme indiqué ci-dessous:

<persistence-unit name="yourUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<non-jta-data-source>java:comp/env/jdbc/yourDs</non-jta-data-source>        
<properties>
<property name="eclipselink.session.customizer" value="com.company.yourproject.yourpackage.JPAEclipseLinkSessionCustomizer"/>        
</properties>
</persistence-unit>

Vous avez besoin de cette solution de contournement pour Apache Tomcat.

Lien donné n'est pas de répondre. J'ai trouvé une copie du fichier dans: code.google.com/p/buzzwords/source/browse/trunk/Buzzwords/maven/...

Définir la source de données d'URL "jdbc/myDs"

<non-jta-data-source>jdbc/myDs</non-jta-data-source>

Cela provoque une autre exception: javax.de nommage.NameNotFoundException: Nom jdbc n'est pas lié, dans ce Contexte, au org.apache.de nommage.NamingContext.recherche(NamingContext.java:770) at org.apache.de nommage.NamingContext.recherche(NamingContext.java:140) at org.apache.de nommage.SelectorContext.recherche(SelectorContext.java:121) at javax.de nommage.InitialContext.recherche(InitialContext.java:396) at org.eclipse.la persistance.les sessions.JNDIConnector.connect(JNDIConnector.java:110) at org.eclipse.la persistance.les sessions.JNDIConnector.connect(JNDIConnector.java:94)

J'espère que tu as pu résoudre le problème avec les commentaires ...

J'ai corrigé par l'ajout d'une propriété "javax.la persistance.nonJtaDataSource" avec la même valeur que l'élément non-jta-data-source

Je pense que vous avez besoin de coder une solution de contournement pour le javax.naming.NamingException: This context must be accessed throught a java: URL exception tel que détaillé au http://wiki.eclipse.org/EclipseLink/Examples/JPA/Tomcat_Web_Tutorial#Session_Customizer

Année 2015 actualisation: - je pas sûr que Eclipselink SessionCustomizer est nécessaire. Dans mon test de tous les travaux sans (Tomcat 7.x, Java 7.x, Eclipselink 2.4.x).

Certains anciens matériaux suggèrent problème spécifique avec Tomcat 5/6 et la façon particulière de le résoudre.
