Mas não consigo encontrar o erro,pois fiz o .xml do spring:

A classe de fábrica de repositórios já tem o bean:

package sca.domain.repositorio;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class RepositorioFabrica {

	private static String rootContextDirectoryClassPath = "resources/ctx";
	private static String startupContextPath = rootContextDirectoryClassPath
			+ "/sca-springConfig.xml";
	private static ApplicationContext ctx = new FileSystemXmlApplicationContext(
			startupContextPath);


	public static SalaRepositorio getSalaRepositorio(){
		return (SalaRepositorio) ctx
			.getBean("salaRepositorio");
	}
	
}

E a classe de repositório está feita:

package sca.domain.repositorio;

import java.util.List;

import sca.domain.Sala;
import sca.infra.dao.DAOException;
import sca.infra.dao.SalaDAO;

public class SalaRepositorio {

	private SalaDAO salaDAO;

	public void setSalaDao(SalaDAO salaDAO) {
		this.salaDAO = salaDAO;
	}

	public void incluir(Sala sala) throws RepositorioException {
		try {
			salaDAO.incluir(sala);
		} catch (DAOException e) {
			throw new RepositorioException(e.getMessage(), e);//"Erro na inclusão da sala"
		}
	}

	public void excluir(Sala sala) throws RepositorioException {
		try {
			salaDAO.excluir(sala);
		} 
		catch (DAOException e) {
			throw new RepositorioException("Erro na exclusão da Sala", e);
		}
	}
	
	public List<Sala> obterTodasSalas()throws RepositorioException{
		try{
			return salaDAO.obterTodasSalas();
		}catch (DAOException e) {
			throw new RepositorioException("Erro na recuperação das Salas", e);
		}
	}

}

A classe que conecta com o banco também está feita:

package sca.infra.dao;

import java.util.List;

import sca.domain.Sala;


public class SalaDAOJpa implements SalaDAO{

	private GenericDAOJPA<Sala> genericDAO = new GenericDAOJPA<Sala>();

	public void atualizar(Sala sala) throws DAOException {
		genericDAO.alterar(sala);
	}

	@Override
	public void excluir(Sala sala) throws DAOException {
		genericDAO.excluir(Sala.class, sala.getId());
	}

	@Override
	public void incluir(Sala sala) throws DAOException {
		genericDAO.incluir(sala);
	}
	
	@Override
	public List<Sala> obterTodasSalas()throws DAOException{
		return genericDAO.obterTodos(Sala.class);
	}
}

e a interface também:

package sca.infra.dao;

import java.util.List;

import sca.domain.Sala;

public interface SalaDAO {

	void excluir(Sala sala) throws DAOException;

	void incluir(Sala sala) throws DAOException;

	List<Sala> obterTodasSalas() throws DAOException;

}

Estou desesperado, pois meu tempo já é curto e não posso perdê-lo com isso.

tentou colocaro o bean salaDAO no contexto do spring?

public static ...{ return (SalaDAO) ctx.getBean("salaDAO"); }

Na verdade, a classe RepositorioFabrica é assim:

package sca.domain.repositorio;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class RepositorioFabrica {

	private static String rootContextDirectoryClassPath = "resources/ctx";
	private static String startupContextPath = rootContextDirectoryClassPath
			+ "/sca-springConfig.xml";
	private static ApplicationContext ctx = new FileSystemXmlApplicationContext(
			startupContextPath);

	public static ProfessorRepositorio getProfessorRepositorio() {
		return (ProfessorRepositorio) ctx.getBean("professorRepositorio");
	}

	public static DisciplinaRepositorio getDisciplinaRepositorio() {
		return (DisciplinaRepositorio) ctx.getBean("disciplinaRepositorio");
	}

	public static GradeDisponibilidadeRepositorio getGradeDisponibilidadeRepositorio() {
		return (GradeDisponibilidadeRepositorio) ctx
				.getBean("gradeDisponibilidadeRepositorio");
	}

	public static TitulacaoRepositorio getTitulacaoRepositorio() {
		return (TitulacaoRepositorio) ctx
				.getBean("titulacaoRepositorio");
	}

	public static AlunoRepositorio getAlunoRepositorio() {
		return (AlunoRepositorio) ctx.getBean("alunoRepositorio");
	}

	public static TurmaRepositorio getTurmaRepositorio() {
		return (TurmaRepositorio) ctx.getBean("turmaRepositorio");
	}

	public static InscricaoRepositorio getInscricaoRepositorio() {
		return (InscricaoRepositorio) ctx.getBean("inscricaoRepositorio");
	}

	public static ItemDisponibilidadeRepositorio getItemDisponibilidadeRepositorio() {
		return (ItemDisponibilidadeRepositorio) ctx
				.getBean("itemDisponibilidadeRepositorio");
	}
	
	public static SemestresCursadosRepositorio getSemestresCursadosRepositorio(){
		return (SemestresCursadosRepositorio) ctx
			.getBean("semestresCursadosRepositorio");
	}
	
	public static SemestreLetivoRepositorio getSemetreLetivoRepositorio(){
		return (SemestreLetivoRepositorio) ctx
			.getBean("semetreLetivoRepositorio");
	}

	public static SalaRepositorio getSalaRepositorio(){
		return (SalaRepositorio) ctx
			.getBean("salaRepositorio");
	}
	
}

Onde todos os repositórios funcionam perfeitamente, o problema é com a salaRepositorio, que acabei de adicionar.

O problema é o seguinte.

Na sua classe Java está assim:

..
private SalaDAO salaDAO;  
   
     public void setSalaDao(SalaDAO salaDAO) {  
         this.salaDAO = salaDAO;  
     }

Nesse caso ele vai injetar a propriedade salaDao e nao salaDAO…é só alterar no xml do spring para:

..
     <bean id="salaRepositorio" class="sca.domain.repositorio.SalaRepositorio">  
         <property name="salaDao">  
             <ref local="salaDAO"/>  
         </property>  
     </bean>  
..

Ou mudar seu metodo set para
public void setSalaDAO…

Meu Deus!!! Que coisa horrível!! Eu num sabia que até os métodos teriam que ter case sensitive com jpa.
Muitíssimo obrigado, Luciano.
