CmpSellmeal
和CmpMeals 是多对一关系
CmpSellmeal主键(stufferid,orderdate,timeid)
CmpSellmeal其他字段mealsid.
CmpMeals 主键(orderdate,timeid,id)
CmpSellmeal 通过 orderdate -- orderdate,timeid-timeid,mealsid-CmpMeals.id关联，
CmpSellMeal 的create 方法
public CmpSellmealPK ejbCreate(Long stufferId, java.sql.Date orderDate, Integer mealSellTimeID, CmpMeals meals, Integer amount, String ineffect) throws CreateException {
setStufferId ( stufferId );
setOrderDate(orderDate);
setMealSellTimeID(mealSellTimeID);
return new CmpSellmealPK( stufferId,orderDate,mealSellTimeID);
}
public void ejbPostCreate(Long stufferId, java.sql.Date orderDate, Integer mealSellTimeID, CmpMeals meals, Integer amount, String ineffect) throws CreateException {
setCmpMeals(meals);
}

编译正常，运行出现下面异常。
