Thanks for your answer, but in the doc I found that :
By convention, module builder class names end in Module and are final classes.
And my module is :
package papo.ioc.services;
public final class UserModule {
public UserService build() {
return new UserServiceImpl();
}
}
Do we have to use only AppModule and not our custom Module such mine UserModule?
Ok for the Manifest, it was a try.

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.
This will be
