I dont think you have a column named "numeroLinea" in your table. I guess, you have a column named NUMERO_LINEA. Looking back at the code that you posted, i guess you will have to move the @Column annotations to the PK class. Something like this:

Entity class (remove the @Column annotation from this class for the Ids):
@Entity
  | @Table(name="APUNTES")
  | @IdClass(ApuntesPK.class)
  | public class Apuntes implements Serializable{
  | 	//Claves
  | 	@Id
  | 	private Integer empresa;
  | 
  | 	@Id
  | 	private Integer numeroAsiento;
  | 
  | 	@Id
  | 	private Integer numeroLinea;
  | 
  | 	private String modificado;
  | 	.......
  | 	others fields and methods get/set
  | 
  | }

The PK class (introduce the @Column annotation on the id columns):

  | public class ApuntesPK implements Serializable {
  | 
  | 	@Column(name="EMPRESA")
  | 	private Integer empresa;
  | 
  | 	@Column(name="NUMERO_ASIENTO")
  | 	private Integer numeroLinea;
  | 
  | 	@Column(name="NUMERO_LINEA")
  | 	private Integer numeroAsiento;
  | 
  | 	//private static final long serialVersionUID = 1L;
  | 
  | 	public ApuntesPK() {
  | 
  | }
