Hello All,

I am relatively new to Hibernate and hence this question. I have a java class that contains elements of the type java.util.List.

public class Application extends DataObject {

private List investments = null;

public List getInvestments() {
return investments;
}

public void setInvestments(List investments) {
this.investments = investments;
}

}


I am creating the Hibernate mapping file. How do I map an attribute of the type java.util.List.

Any help will be highly appreciated. If you can point me to the right place in the documentation, that will be great too.

Regards,

U can map a list using <bag> tag or <list> tag
if u use <bag> then the mapping would be like this in accordance to ur class
<bag name="investments">
<key column="column refering to application id"/>
<one-to-many class="ur_investment_class" />
</bag>

in the case of <list> tag u have to maintain an additional column holding the list index(i.e ur invetments insertion order) in ur DB as well as in ur class. Then the mapping will be
<list name="investemnts">
<key column="column refering to application id"/>
<index name="index_property_name" column="index_column" />
<one-to-many class="ur_investment_class" />
</list>

as per my knowledge this is the soultion.

Thanks for the response Pokuri.

I am trying out both the solutions.

Will select one.

Again, appreciate your response.
