How to host JSONB over Postgres database with JPA

I am trying to create a REST application using Jersey, Gson, JPA and I would like to put a JSON object in a JSON or JSONB database field in Postgres.

I tried to do something like this: How to use the Postgres JSONB datatype with JPA? but my table will see the type "VARCHAR" instead of "JSONB".

My essence:

@Entity
@Table(name = "votes")

public class Votes {

@Id
@GeneratedValue
private int id;
private int idSocialChoice;

@Convert(converter=JsonConverter.class)
private JsonObject vote;

public Votes() {
}

public JsonObject getVote() {
    return vote;
}

public void setVote(JsonObject vote) {
    this.vote = vote;
}

public int getIdSocialChoice() {
    return idSocialChoice;
}

public void setIdSocialChoice(int idSocialChoice) {
    this.idSocialChoice = idSocialChoice;
}

      

        
        
        
      

    

How I insert my object:

Votes votes0 = new Votes();
votes0.setIdSocialChoice(3);

JsonObject object = Json.createObjectBuilder().build();
votes0.setVote(object);

List<Votes> listvotes = new ArrayList<Votes>();
listvotes.add(votes0);

ModelEntities.insertVotes(listvotes);

      

        
        
        
      

    

InsertVotes method:

public static void insertVotes(List<Votes> animalList) {

    CrudServiceBean crudServiceBean = new CrudServiceBean(CrudServiceBean.PU_DB);
    crudServiceBean.newTransaction();

    for(Votes votes : animalList)
        crudServiceBean.create(votes);

    crudServiceBean.commit();

    crudServiceBean.closeTransaction();

}

      

        
        
        
      

    

Create a crudServiceBean.create method:

public  <T> T create(T t) {
    this.em.persist(t);
    this.em.flush();
    this.em.refresh(t);
    return t;
}

      

        
        
        
      

    

My JPA provider creates my schema like this (createDDL_ddlGeneration.sql):

CREATE TABLE votes (ID INTEGER NOT NULL, IDSOCIALCHOICE INTEGER, VOTE VARCHAR(255), PRIMARY KEY (ID))

      

        
        
        
      

    

I would also avoid using Hibernate.

Thank.
