Question

I am working on project using java playframework 1.2.4 and I have a @Entity class. It is look like

@Entity
public class EmployeeType extends Model {
    public static enum TYPE { HOURLY, DAILY, MONTHLY };
    public static enum NATIONALITY { LOCAL, FOREIGN };
    @Required
    @Enumerated(EnumType.STRING)
    public TYPE type;
    @Required
    @Enumerated(EnumType.STRING)
    public NATIONALITY nationality;
}

And in my controller class I want to get list of EmployeeTypes using my 2 enum attributes.
Query looks like

Query query = JPA.em().createQuery("SELECT e FROM EmployeeType e where " +
            "e.nationality = :nationality " +
            "and e.type = :type");
query.setParameter("nationality", NATIONALITY.LOCAL);
query.setParameter("type", TYPE.HOURLY);

List<models.EmployeeType> employeeType = query.getResultList()

Gives this error: IllegalArgumentException occured : Parameter value [LOCAL] was not matching type [models.EmployeeType$NATIONALITY]

What should i do?

Answer 1

The error is possibly because of the fact that your enums are nested in your entity. You need to access it on entity name.

You can change your setParameter code to: –

query.setParameter("nationality", EmployeeType.NATIONALITY.LOCAL);
query.setParameter("type", EmployeeType.TYPE.HOURLY);
