Spring par l'exemple

**sgamette** · 11/10/2010, 00h12

Dabord merci d'éssayer de m'aider.

J'ai commencé a étudier Spring Jdbc je souhaite faire tourner un exemple
j'utilise Maven donc je vous soumets le Pom et l'erreur provonant de la console ainsi que mon main.
Et pour finir le beans.xml
Derby est bien lancé et configuré et la table vehicule est paramétrée et opérationnel.

Voici l'erreur que j'ai dans la console eclipse

Code :

donc c'est le code d'exemple d'un bouquin il y a quelque chose qui m'échappe.

merci d'avance pour votre aide

Bonjour,
pour commencer tu pourrais faire attention un minimum à ton orthographe et à ta grammaire.

Sinon :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'initialsize' of bean class [org.apache.commons.dbcp.BasicDataSource]: Bean property 'initialsize' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Ne serait-ce pas plutôt "initialSize" ? Et probablement pareil pour maxActive. La configuration doit respecter la casse des noms.
