Salut si tu pouvais, mettre tes fichiers de contexte ça aiderais à voir si tu as vraiment configuré une datasource car c'est ce que dit ton message d'erreur.

context est null tout simplement…
problème de configuration de votre projet : application-context.xml n'est pas dans le class path du test.

**chahrazedd** · 16/07/2011, 01h53

j'ai pas compris qu'est ce que je dois faire alors pouvez vous m'expliquer encore un peu je suis débutante

et j'aime bien en sortir de ce pb qui m'a trop géné merci d'avance

**Khaled.Noordin** · 17/07/2011, 12h24

salut, pour commencer la propriété de source de données elle s'écrit dataSource et pas datasource, c'est ce que dit ta première ligne de trace d'erreur "No property 'datasource' found"

change la ligne 19 par <property name="dataSource" ref="datasource"/>

et la ligne context = new ClassPathXmlApplicationContext("application-context.xml");
est douteuse donc revois bien le chemin que tu donne.
