package javax.la persistance ne pas exister malgré Netbeans ajoutant le module Eclipselink

Deux partie de la question:

première partie: JAR est requis? Ne pas javax.persistence-2.0.0.jar les classes, en particulier javax.la persistance.*?

package javax.la persistance ne pas exister malgré Netbeans ajoutant le module Eclipselink

Deuxième partie de la question est, quelle est (potentiellement) de mal avec Netbeans? Jusqu'à hier, il semblait que l'IDE serait automagiquement ajouter des catégories à classpath quand, comme ici, la génération d'un @Entity classe à partir d'une base de données existante. Dans ce cas particulier, Netbeans n'a add JAR.

Cependant, parce qu'ils sont ajoutés à l'extérieur, en projet, il n'y a pas de dossier lib. Malheureusement, je ne suis pas familier encore assez pour vraiment plonger dans build.xml pour voir ce qui se passe, mais à partir du Gestionnaire de Bibliothèque, on dirait qu'ils sont comme ça:

thufir@dur:~$ tree netbeans-7.1.1/java/modules/ext/eclipselink/
netbeans-7.1.1/java/modules/ext/eclipselink/

├── javax.persistence-2.0.jar
└── org.eclipse.persistence.jpa.jpql_1.0.0.jar
0 directories, 4 files
thufir@dur:~$

Il semble tout simplement ne pas rentrer avec mon souvenir que des mesures supplémentaires, le téléchargement selon le BOCAL est manquant, a été requis dans le passé. Pourrait un paramètre dans Netbeans être incorrect ou endommagé?

    La différence semble que le projet de 13 ans a un ./dossier lib, alors que 12 est à l'aide de "externes" POT de l'.

    Peut-être mon Netbeans installation est corrompu, ou d'un mauvais réglage, ou j'ai eu la mauvaise approche pour le projet 12? J'aimerais le faire avec JAR externe, comme un projet de 12, parce que les différentes fonctionnalités, comme le Gestionnaire de Bibliothèque, de mieux fonctionner.
