Hi Martijn. Thanks for the quick response.
Are you saying that the dao and the service should have the InjectorHolder code, rather than the @Repository and @Service tags?

@SpringBean only works with Components. For all other uses you should either call InjectorHolder.getInjector().inject(this) in your constructor or use Salve.

I have created a new small project to try to figure out how to use the SpringBean, Service, and Repository annotations with Wicket, Spring, Hibernate, Maven and Eclipse. However, I am getting an error with a user DAO that I have created. I have a service that is using the dao tagged as @Service, I have the DAO in the service tagged with @SpringBean, and the DAO code itself is tagged with @Repository. The service that is using the DAO is getting found correctly. When I have the InjectorHolder code in the dao constructor, I get an error that says 'InjectorHolder has not been assigned an injector' When I comment out the InjectorHolder line in the dao constructor, the DAO is null, and getUserDAO throws an exception. Since I am not certain that I can attach files, I will insert the relevant code and exceptions into this email. Any pointers you can give would be greatly appreciated. Thanks very very much, Bruce.
