Spring 3.0.3 + @Component + @Autowired - NoSuchBeanDefinitionException

Aloha galera. Tenho um projeto que hoje usa Spring 3.0.3.

Meus DAOs são @Components e são injetados para dentro dos Services com @Autowired. Os DAOS estão em uma aplicação Core, que é uma dependência da minha aplicação principal.

Anteriormente, foi uma aplicação comum, criada como um novo projeto no Eclipse, mas agora deixamos todas elas gerenciadas pelo Maven.

O problema começou a ocorrer justamente depois de a deixarmos gerenciadas pelo Maven. O seguinte erro começou a ocorrer:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ativacaoWSImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private br.com.sistema.service.AtivacaoService br.com.sistema.ws.AtivacaoWSImpl.service; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ativacaoServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: protected br.com.sistema.dao.AgenciaDAO br.com.sistema.service.AtivacaoIoCRepository.agenciaDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [br.com.sistema.dao.AgenciaDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Um fato curioso é que o erro só ocorre quando executo de dentro do Eclipse. Quando eu empacoto o Sistema e subo o Tomcat, o mesmo funciona corretamente. O que posso estar fazendo de errado ????

Segue as classes...

AtivacaoWSImpl.java

@WebService(endpointInterface = "br.com.sistema.ws.AtivacaoWS")
@Component
public class AtivacaoWSImpl implements AtivacaoWS {

	private static final Logger LOGGER = Logger.getLogger(AtivacaoWSImpl.class);

	Properties props = new MonitorUtil().getPropertiesConfig();

	@Resource
	WebServiceContext wsContext;

	@Autowired
	@Qualifier(value = "AtivServImpl")
	private AtivacaoService service;

AtivacaoServiceImpl.java

@Service
@Qualifier(value="AtivServImpl")
public class AtivacaoServiceImpl  extends AtivacaoIoCRepository implements AtivacaoService{

e em AtivacaoIoCRepository.java

@Component
public abstract class AtivacaoIoCRepository {
	
	@Autowired
	protected AgenciaDAO agenciaDao;

AgenciaDAO.java

package br.com.sistema.dao;

@Component
public class AgenciaDAO extends GenericDAOImpl<Agencia>{

}

No applicationContext.xml o pacote de injeção está definido da seguinte forma:

<context:component-scan   base-package="br.com.sistema" />

Realmente algum detalhe está escapando e a única coisa que me passou pela mente foi o fato de anteriormente a estrutura de pacotes estar diretamente em src/ e agora em src/main/java (devido ao maven), mas pensei que isso seria transparente.

Se alguém puder dar uma luz sobre o problema e sua solução...

PS: Coloquei somente as partes essenciais das classes, pois o Sistema não é meu.
