How do I use a primary key that is a foreign key to another

[dornus]

I have 2 tables.

Table 1
---------
int myId (Primary Key)
etc...

Table 2
---------
int myForeignId (Primary Key, and is a foreign key of Table 1's myId)
etc...

How do I set up annotations for table2?
I have tried tagging myForeignId with @Id, @JoinColumn, separately and together.

What is the correct way to do this?

Thanks

Is anyone able to answer this?

I have the following which is not working. I need to know the correct way of doing this.

public class TableOne{
 private int myId;
 // more variables, etc...

 @Id(generate = GeneratorType.AUTO)
 public int getMyId() {
 return myId;
 }

 public void setMyId( int myId ) {
 this.myId = myId;
 }

 // more getters and setters for misc variables etc...
}

public class TableTwo{
 private TableOne myId;
 // more variables, etc...

 @Id(generate = GeneratorType.AUTO) //DOESN'T WORK
 @ManyToOne //DOESN'T WORK
 @JoinColumn(name = "myForeignId") //DOESN'T WORK
 public TableOne getMyId() {
 return myId;
 }

 public void setMyId( TableOne myId ) {
 this.myId = myId;
 }

 // more getters and setters for misc variables etc...
}

@Id
String myOtherEntityId;

@ManyToOne
@JoinColumn(insertable=false, updatable=false, name="myOtherEntityId")
MyOtherEntity myOtherEntity;

Excellent! Thank you for the response. I modified the code to the following and it works.

public class TableTwo{
 private int myForeignId;
 private TableOne myId;
 // more variables, etc...

 @Id
 public int getMyForeignId() {
 return myForeignId;
 }
 public void setMyForeignId( int myForeignId ) {
 this.myForeignId = myForeignId;
 }

 @ManyToOne
 @JoinColumn(insertable=false, updatable=false, name="myForeignId")
 public TableOne getMyId() {
 return myId;
 }

 public void setMyId( TableOne myId ) {
 this.myId = myId;
 }

 // more getters and setters for misc variables etc...
}
