How to Utilizing the variable define in non-entity base class, in the entity
sub class.
---------------------------------------------------------------------------------------
Key: OPENJPA-1564
URL: https://issues.apache.org/jira/browse/OPENJPA-1564
Project: OpenJPA
Issue Type: Question
Reporter: Rajeev Chaudhary
I have BaseFacDto class with defined properties. I have sub-class FacDto
(entity) extending BaseFacDto.
public abstract class BaseFacDto {
@Column(name="FAC_NAME")
public String facName;
---
}
@Entity
@Table(name="FAC")
public class FacDto extends BaseFacDto implements Serializable {
public FacDto(){}
@Id @Column(name="FAC_ID", nullable = false)
private String facId;
@Column(name="FAC_ADDRESS")
private String facAddress;
@Column(name="LABID")
}
Questions:
1. When the query fac = clep.find(FacDto.class, facId); I don't see
FAC_NAME in the logged SQL generated. Since Base class has this variable, so
sub-class also get it by inheritance. Please verify. I have define it like
this in base class
@Column(name="FAC_NAME")
private String facName;
2. I also tried this thing. I created the variable in the sub-class without
getter-setter. Now I see the FAC_NAME in the sql log. But the issue now is when
I execute getter methods ( inherited from base class). the value is always null.
@Column(name="FAC_NAME")
private String facName;
3. How OpenJPA different from JPA. I see that all OpenJpa sample uses the
javax.persistance.jar (JPA jar). I am little confused over this. Please clarify

Please help.
Thanks in advance
