Bonjour,

j'essaie tant bien que mal de réaliser le tuto sur Tapestry Spring et JPA : http://loic-frering.developpez.com/t...ring-tapestry/.

Je rencontre une erreur lors de l'accès à l'écran de gestion des utilisateurs :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
No service implements the interface test.sample.skillbrowser.services.UserManager.

Voici le code (ou plutot les annotations) de mon service UserManagerImpl

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2

4
 
@Service("userManager")
@Transactional(propagation = Propagation.REQUIRED, readOnly = true)
public class UserManagerImpl implements UserManager {

Y'a quelque chose qui cloche docteur?

[supermanu]

Visiblement tu n'utilises pas le même nom de package que dans le tuto : test.sample.skillbrowser au lieu de net.ilabs.skillbrowser.

Ce n'est pas grave, sauf que tu dois modifier le fichier de configuration applicationContextJpa.xml.
Et remplacer

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
<context:component-scan base-package="net.ilabs.skillbrowser" />

par

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
<context:component-scan base-package="test.sample.skillbrowser" />

Comme ça Spring va regarder dans ton package et instancier les bean qui comporte des annotations, dont UserManagerImpl.

[bumbo500]

Merci supermanu, mais non mon fichier applicationContextJpa.xml est correct. J'ai bien renommé le package du tuto mais j'ai vérifié et j'ai également fait la modif dans ce fichier.
Voici l'erreur obtenue:

[aymen83]

bonjour, d'après le log il y a une classe qui n'est pas correctement configurée.
il ne la trouve pas.

[bumbo500]

Ok merci.

Mais l'erreur de configuration vient-elle des annotations ou du code java ou des fichiers de configuraton? J'ai revérifié plusieurs fois et vraiment je ne comprends pas!
