jusque la tout fonctionne correctement !
J'ai voulu isoler le traitement dans URLClassLoader et ai remplacé le new par :
Code:
1
2
|
loader.loadClass("com.test.crystal.ReportEdition").newInstance() |
j'ai aussi supprimer les libs crystal du classpath d'origine et les ai ajouté à mon URLClassLoader.
mais là c'est le drame, je me retrouve avec une exception :?, alors que la seul différence est le classLoader :

- JRCAgent1 received request: closeServerAgent
- JRCAgent1 has cleaned up and closed down the report
Quelqu'un aurait il une explication logique a ce problème ?
Merci d'avance !
