Boa tarde pessoal! Estou com um problema na minha aplicação desktop. Uso o hibernate e o banco é o mySQL 5.
O erro é o seguinte:
org.hibernate.QueryException: could not resolve property: idCurso of: dominio.Turma [SELECT p FROM dominio.Turma p where p.idCurso = ‘2’]

e mais um monte de linha dando seqüência nisto ai.
Acontece que pelo que analisei está tudo certo:
Turma.java
[code]public class Turma implements java.io.Serializable {
private static final long serialVersionUID = 1L;
private int idTurma;
private Curso curso;
private String nome;
private String turno;
private Set<Matricula> matriculas = new HashSet<Matricula>(0);
private Set<Matricula> matriculas_1 = new HashSet<Matricula>(0);
private Set<Ministra> ministras = new HashSet<Ministra>(0);
private Set<Ministra> ministras_1 = new HashSet<Ministra>(0);
private static final HibernateRepositorio hibernateRepositorio = new HibernateRepositorio();
public Turma() {
}
public Turma(Curso curso, String nome, String turno) {
this.curso = curso;
this.nome = nome;
this.turno = turno;
}
public Turma(Curso curso, String nome, String turno,
Set<Matricula> matriculas, Set<Matricula> matriculas_1,
Set<Ministra> ministras, Set<Ministra> ministras_1) {
this.curso = curso;
this.nome = nome;
this.turno = turno;
this.matriculas = matriculas;
this.matriculas_1 = matriculas_1;
this.ministras = ministras;
this.ministras_1 = ministras_1;
}

Método que está gerando este erro, que se encontra na classe HibernateRepositorio.java
public ArrayList<Object> consultarPor(Object objeto, String atributo, Object campo) throws HibernateException {
ArrayList<Object> listaObjetos = new ArrayList<Object>();
try {
session = HibernateUtil.currentSession();
Query query = session.createQuery("SELECT p FROM " + objeto.getClass().getName() + " p where p." + atributo + " = '" + campo + "'");
for(Iterator it=query.iterate();it.hasNext();){
listaObjetos.add(it.next());
}
} catch (Exception e) {
session.cancelQuery();
e.printStackTrace();
} finally {
HibernateUtil.sessionClose();
}
return listaObjetos;
}Alguém poderia desvendar este mistério? :?
