En utilisant WTP 1.5 et Eclipse 3.2, lors du déploiement de modules EJBs dans JOnAS, il arrive de rencontrer cette erreur dans la console JOnAS :

Comme l’explique à juste titre le message d’erreur, la tâche Ant qui génère les EJBs est lancée par le JRE au lieu du JDK^[1]. Et c’est pourquoi l’outil GenIC ne trouve pas le programme javac.

Le problème peut être résolu en lancant votre serveur d’applications^[2] avec le JDK au lieu du JRE Pour celà, il faut procéder ainsi :

• Vérifier la configuration du JDK dans Eclipse
  • Aller dans Windows -> Preferences… -> Java -> Installed JREs
  • S’il n’y a aucun JDK dans la liste des Installed JRE, en ajouter un soit avec Add… soit avec Search…
• Configurer le serveur d’applications JOnAS avec WTP
  • Aller dans Windows -> Preferences… -> Server -> Installed Runtimes
  • Sélectionner le serveur d’applications utilisé^[3] et cliquer sur Edit…
  • Modifier le JRE en sélectionnant un JDK, puis cliquer sur Finish et enfin sur OK

Pour que la modification soit effective, il faut redémarrer le serveur d’application bien entendu. Maintenant vos petits EJBs peuvent être déployés !

Notes

[1] Il semble que ce soit un bug de Ant !?

[2] Ici JOnAS.

[3] Dans mon cas, c’est JOnAS v4.

En utilisant Ant avec Eclipse, il arrive souvent de rencontrer ce genre d’erreur :

Cette erreur n’est qu’ un problème de path.

En utilisant Ant avec Eclipse, il arrive souvent de rencontrer ce genre d’erreur :

Ces erreurs ne sont que des problèmes de classpath.
