Hibernate Persisting model

[Aleksandar Mitrev]

I'm creating application who contains two model class Student and Grade and using org.springframework.orm.hibernate3.LocalSessionFactoryBean to persist them
The two model class and the relation between them is:

package model;
public class Student {
   private Integer id;
	private String name;
	private String lastName;
	private Integer indexNo;
	private List<Grade> grades = new ArrayList<Grade>();
          ............................
            getters setters

package model
public class Grade {
	private Integer id;
	private Integer studentId;
	private Integer grade ;

              getters setters
              ........................

I've manage to persist the two classes separable with out the relation between(the composition in Student class)
I'm wondering is there something like

<hibernate-mapping>
       <class name="model.Student" table="Student" catalog="Education">
       .........................
      <ono-to-many name="grades" class="model.Grade" property-ref="studentId" />
       ........................
</hibernate-mapping>

that like a state to put it in the hibernate-mapping and make the persistence with the corresponding relation.
I'm not using JPA Annotation in the model and my tables in the database are

Student table:

ID                  NAME          LAST_NAME      INDEX_NUMBER                              
-----------------------------------------------------------------------                              
int               varchar         varchar          int                                                                 
auto               not null       not null         not null                                                       
increment                                                                                                   
Primary Key                                                                                                
not null     

Grade table:

ID                 STUDENT_ID         GRADE
------------------------------------------------------
int                int                  int
auto               Foreigner key 
increment
Primary Key

Well, you just add the association mapping to your mapping.

See the Hibernate documentation for xml mapping of associations here
http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/associations.html#assoc-unidirectional

I am also going to move this to the ORM forum as this isn't a Spring question. Thanks

Thanks mark your reply gave me direction what my mistake is
I was getting error on one-to-many declaration and a assuming that my mistake is there but actual my mistake was that I've didn't added the spring-jpa jar
Thanks again
