All friends…

I have two classes promotion and grade

Class Grade {
private long gradeId;
private String gradeName;

getters/setters………….
}


Class Promotion {
private long promotionId;
private String promotionName;
private Grade grade;

getters/setters………….
}


Grade table
GRADE_ID
GRADE_NAME

Promotion Table
PROMOTION_ID
PROMOTION_NAME
GRADE_ID


Can any one suggest.. how can I map Promotion class in promotion.hbm.xml
Difficulty with me is that Promotion class contains Grade object … I just need its GradeId only to promotion table..

Thanks to all

Here's a little tutorial on how to map one to one associations with Hibernate. The example uses JPA, but the ideas are equivalent to using mapping files:
