Java - Hibernate - mappedBy issue

I have a Java class with Hibernate annotations that refers to another POJO:

@Entity
@Table(name = "Patient_Visit_Transaction")
public class PatientVisitTransaction extends Bean {
    @OneToMany(fetch = FetchType.LAZY)
    @JoinColumn(name = "transaction_id")
    List<TransactionNoteDW> notes;
    ....
}

The other class is this:

@Entity
@Table(name = "Transaction_note_dw")
public class TransactionNoteDW extends DateAuditableBean {
    @Id
    @Column(name = "note_seq")
    private long id;

    @Column(name = "transaction_id")
    private String transactionId;
}

I am trying to delete a PatientVisitTransaction and I get an error: mappedBy reference an unknown target entity property: TransactionNoteDW.transaction_id in PatientVisitTransaction.notes.
I guess it is trying to map the notes to transaction_id. How do I specify the correct mapping or am I completely off on my assessment?

I think you might want to map like this:

public class TransactionNoteDW extends DateAuditableBean {
    //....
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "patient_id")
    private PatientVisitTransaction patient;
}
public class PatientVisitTransaction extends Bean {
    //....
    @OneToMany(fetch = FetchType.LAZY, mappedBy = "patient")
    List<TransactionNoteDW> notes;
}
