I am trying to insert data from class into db
here my model class
package models;
import java.util.*;
import javax.persistence.*;
import javax.persistence.Entity;
import javax.validation.*;
import play.data.validation.Constraints;
import play.data.validation.Constraints.*;
import play.api.db.*;
import play.db.jpa.*;
import javax.persistence.EntityManager;
@Entity
public class MedicalIncident {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public int id;
@Constraints.Required
public String month;
@Constraints.Required
public String place;
@Constraints.Required
public String unit;
@Constraints.Required
public String incident_type;
@Constraints.Required
public int age;
/**
* Insert this new incident submission.
*/
public void toDataBase() {
// persist object - add to entity manager
JPA.em().merge(this);
JPA.em().persist(this);
}
}
.merge method gives me error:

All I can see it shows me that Column "MEDICALINC0_._EBEAN_INTERCEPT" not found which is quite obvious cause I really dosnt have that column in db. My db:
create table MedicalIncident (
id bigint not null,
month varchar(255),
place varchar(255),
unit varchar(255),
incident_type varchar(255),
age bigint,
constraint pk_MedicalIncident primary key (id))
;
Or should I use persist() method?
Try disabling the EBean enhancement. In your
conf/application.conffile comment out everything you have with ebean*. Also do the same with yourbuild.sbtfile.
