So, I'm now on 5.04 and I re-read the documentation about ioc to be
sure I didn't do a mistake when I declared my service.
The module is final and follow the naming convention:
package papo.ioc.services;
public final class UserModule {
public UserService build() {
return new UserServiceImpl();
}
}
And I declared it in the MANIFEST.MF under webroot/META-INF :
Manifest-Version: 1.0
Tapestry-Module-Classes: papo.ioc.services.UserModule
The service interface seems ok:
package papo.ioc.services;
import papo.exception.PapoException;
import papo.model.User;
public interface UserService {
public User getAuthenticatedUser(String login, String password)
throws PapoException;
}
The implementation looks normal:
package papo.ioc.services;
import org.apache.log4j.Logger;
import papo.dao.UserDao;
import papo.exception.PapoException;
import papo.model.User;
public class UserServiceImpl implements UserService {
/** Obtain a suitable logger */
private static Logger logger =
Logger.getLogger(UserServiceImpl.class.getName());
public User getAuthenticatedUser(String login, String password)
throws PapoException {
UserDao dao = new UserDao();
User user = null;
try {
user = dao.searchUser(login, password);
}
catch (PapoException pe) {
logger.error("The authentication has failed !!", pe);
throw new PapoException("The authentication has failed !!");
}
return user;
}
}
and the I use it in my Start page:
@Inject
@Service("UserService")
private UserService _userService;
String onSuccess() {
String success = "Home";
String failure = "Start";
try {
_user = _userService.getAuthenticatedUser(_login.getLogin(),
_login.getPassword());
}
catch (PapoException pe) {
_message = "La procedure d'identification a rencontré un probleme !!";
return failure;
}
return success;
}
But I still have the error :
java.lang.ClassNotFoundException
caught an exception while obtaining a class file for papo.pages.Start
exception
java.lang.RuntimeException: Error obtaining injected value for field
papo.pages.Start._userService: No service implements the interface
papo.ioc.services.UserService.
What can I try now?

I was using the 5.03. I just changed for the 5.04 then I tried your proposition
:
"No service implements the interface papo.ioc.services.UserService."
But my implementation, UserServiceImpl is in the same package than its
interface UserService and implements it.
The module UserModule that contains the buildUserService method and return the
UserService is also in this package...
What did I miss??
