Bonjour,

Je suis en train d'apprendre le framework Hibernate sous Eclipse.

J'ai téléchargé Hibernate Tools, j'ai placé les features sous eclipse/features et les plugins sous eclipse/plugins

J'ai créé un projet et j'ai essayé de créer le fichier hibernate.cfg.xml mais ça m'affiche ceci

Could not open the editor: An unexpected exception was thrown.

Quelqu'un saurait-il m'expliquer d'où cela peut-il venir ?

Merci d'avance pour votre aide.

Bonjour,

Utilise l'installation via le Eclipse Marketplace.
Menu Help > Eclipse Marketplace... (en supposant que tu utilises Eclipse Helios) et en faisant une recherche avec "Hibernate" tu devrais tomber dessus.

Tu as aussi le plugin JBoss Tools (plus bas dans le résultat de la recherche).

[faty_br]

J'ai procédé comme vous m'avez dit et il m'a dit que "hibernate tools are already installed" et aussi jboss tools are already installed.

Enfin il m'a affiché ceci:

Your original request has been modified.
"Hibernate Tools" is already installed, so an update will be performed instead.
"JBoss Portlet" is already installed, so an update will be performed instead.
"JBoss Drools Core" is already installed, so an update will be performed instead.
"JMX Console" is already installed, so an update will be performed instead.
"Hibernate Tools" is already installed, so an update will be performed instead.
"JBoss Drools Guvnor" is already installed, so an update will be performed instead.
"JBossAS Tools" is already installed, so an update will be performed instead.
"Project Examples" is already installed, so an update will be performed instead.
"FreeMarker IDE" is already installed, so an update will be performed instead.
"Smooks Tools" is already installed, so an update will be performed instead.
"JBoss WebServices Tools" is already installed, so an update will be performed instead.
"JBoss Archives Tools" is already installed, so an update will be performed instead.
"JBoss Drools Task" is already installed, so an update will be performed instead.

La solution la plus rapide est sans doute de réinstaller Eclipse (bundle JEE) et de remettre le plugin Hibernate via le Marketplace...
