I use SQL Server with hibernate (JPA). One of my columns is named 'plan' so when I try to retrieve
data from this column it returns error:

javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: could not load an entity: [com.gisdata.katastarcg.model.Parcel#component[cadastralMunicipalityId,cantonId,number,subNumber]{subNumber=0, number=191, cadastralMunicipalityId=8, cantonId=70}]

Part of my code to get this column is:
/* Parcel.java */
@Column(name="plan")
public String getPlan() {
return plan;
}

public void setPlan(String plan) {
this.plan = plan;
}

I know that if I change this code to @Column(name="[plan]") I will get good result. But I also use native query which also has
plan column but if I call it now with changed @Column(name="[plan]") it returns error, but it works with @Column(name="plan"). Error:

Code for native query:

Query query = manager.createNativeQuery("SELECT p.srez, p.ko, p.broj, p.podbroj, p.aktivnost, " +
"p.povrsinaI, p.povrsinaK, p.povrsinaP, " +
"p.osnov, p.zemljiste, p.list, p.skica, p.[plan], p.potes, plp.pl FROM esKatParcela p JOIN esPLParcela plp ON p.srez = plp.srez AND " +
"p.ko = plp.ko AND p.broj = plp.broj AND p.podbroj = plp.podbroj WHERE " +
"plp.srez = :srez AND plp.ko = :ko AND plp.pl = :pl", Parcel.class);
query.setParameter("srez", 70);
query.setParameter("ko", 8);
query.setParameter("pl", 17);

List parcels = query.getResultList();

Does anyone know how to solve this problem? Thing is that I need both and native query and retrieving element through
entity class. So if I write "[plan]" the first part of code works, and native query doesn't, but if write just "plan" the first part doesn't work, but native query
code is working.
