The code below leads to the following error:
Caused by: org.hibernate.QueryException: illegal attempt to dereference collection [ho0_.id.Mo] with element property reference [value]



Is it possible to use JQL to process dynamic queries for OnToMany mappings? First class is



@Entity
@Table(name = "ho")
public class Ho

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;

@Column(name="str")
private String str;

@OneToMany(mappedBy = "ho",
targetEntity=Mo.class))
private List<Mo> mo;


// ...constructors, getters and setters




Second Class is



@Entity
@Table(name = "mo")
public class Mo

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;

@ManyToOne
@JoinColumn(name="ho_id")
private Ho ho;

@Column(name="value")
private String value;

// ..constructors, getters and setters



And my service implementation class is



 @Transactional
public RfpODto listRfpOByPage(Pageable pageable)

String query = "SELECT h from Ho h " +
"where h.str = :s " +
"and h.mo.value = :v";

Query q = em.createQuery(query,RfpO.class)
.setParameter("s", "str3")
.setParameter("v", "val3");

List<Object> Hos = q.getResultList();
...



Any help will be appreciated !!
