Composite keys of foreign keys

[kmargo]

Hello Everybody !!

Please, I need to do an Entity with composite keys of foreign keys.

Example:

public class Article implements Serializable {
int articleId;
Author authorId;
String articleDescription;

@Id
public int getArticleId() {...}

@Id
public Author getArticleId() {...}
...
}

Is it possible ?
How can I do it ?

thanks !
Paulo
