I am trying to use annotations to generate my DDL. I have everything working as I like except for one thing. When generating DDL for inherited classes the generated alter table SQL has an add contraint value that is generated like so:

alter table ANGELFISH
add constraint FK71E495B9C27AFB7
foreign key (FK_ANGELFISH_FISH)
references FISH;

I would like to add an annotation so I can control the value of the contraint. The following are the annotations I am using for the Fish class and the AngelFish class. I can't find anywhere in the documentation anything that addresses this. If someone knows how to control the contraint value I would appreciated a tip. Thanks.

@Entity
@Table(name="FISH")
@Inheritance(strategy = InheritanceType.JOINED)
public class Fish implements Serializable
{

private static final long serialVersionUID = 1234567890L;
private Integer id;

@Id
public Integer getId(){
return id;
}
public void setId(Integer id){
this.id = id;
}
.....

and here is the Angel Fish:

@Entity
@Table(name="ANGELFISH")
@PrimaryKeyJoinColumn(name = "ID")
@ForeingKey(name = "FK_ANGELFISH_FISH")
public class AngelFish extends Fish implements Serializable
{

private static final long serialVersionUID = 1234567890L;


private Integer finSize;

@Column(name = "FINSIZE",length=100)
public Integer getFinSize(){
return finSize;
}
.....
