You don't need the MANIFEST.MF.
You do need to name your module correctly, it should be AppModule. The
documention is *very clear* on the naming for that.
Also, you should consider letting Tapestry IoC inject the Log (
org.apache.commons.logging.Log) for your service; cleans up a lot of code
that way.

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?
