@OneToMany mapping cannot find the inverse attribute defined in "mappedBy"

I have a RmgtProfileBVOImpl where I define a @OneToMany mapping:

@Proxy(proxyClass = RmgtProfileBVO.class)
@Table(name = "rmgt_t_profile")
public class RmgtProfileBVOImpl extends AbstractBasePropertiesImpl implements RmgtProfileBVO {	

@OneToMany(mappedBy = "profileId",
			targetEntity = RmgtProfileValidationBVOImpl.class, 
			fetch = FetchType.EAGER, 
			cascade = CascadeType.ALL, 
			orphanRemoval = true)
	private java.util.Set<RmgtProfileValidationBVO> profileValidations = new HashSet<>();

I can see an error for profileId with this message:

Can’t find inverse attribute

Problem is: the profileId is declared in the implementation (RmgtProfileValidationBVO), not in the interface. But I need the set in ProfileBVOImpl to be of interface-type .

This is what the RmgtProfileValidationBVOImpl looks like:

@Table(name = "rmgt_t_profile_validation")
@Proxy(proxyClass = RmgtProfileValidationBVO.class)
public class RmgtProfileValidationBVOImpl implements RmgtProfileValidationBVO {

	@Column(name="fk_profile_id", insertable = false, updatable = false)
	public Long profileId;

Is there a solution to this problem? I tried to work with targetEntity attribute but that did not help here.

The mappedBy attribute must refer to an attribute annotated with @ManyToOne that has the type of the owner of the @OneToMany i.e. @Id @NotNull @ManyToOne(fetch = LAZY, targetEntity = RmgtProfileBVOImpl.class) @JoinColumn(name="fk_profile_id") RmgtProfileBVO profile;, and then you use @OneToMany(mappedBy = "profile")
