Is it possible to use the session.load(class, id) with a composite key?

I have several classes that I have implemented using composite keys such as the following class

public class ASControlSection {

private ASControlSectionCompositeKey ascskey = null;
private String asControlSectionDesc =null;

}

public class ASControlSectionCompositeKey implements Serializable{

private String asStationCode =null;
private String asAllocationCode =null;
private String asControlSectionCode =null;

}

The mapping xml is

hibernate-mapping>
<class name="uk.co.customerinteraction.dao.ASControlSection" table="LTRAPF.TKDYREP">
<composite-id name="ascskey" class="uk.co.customerinteraction.dao.ASControlSectionCompositeKey">
<key-property name="asAllocationCode" column="DYSEC2"/>
<key-property name="asControlSectionCode" column="DYSGC2"/>
<key-property name="asStationCode" column="DYSCC2"/>
</composite-id>
<property name="asControlSectionDesc" column="DYK3NA"/>
</class>
</hibernate-mapping>

At the moment I am using a hibernate Query to retreive the object, but was wondering if I would be better using the session.load(class, id).

If it is possible which is more efficient, the query on the primary key or the session.load?

thanks in advance

Sure, of course you can use it! Thats the whole reason for the composite id class!

load() is supposed to be more efficient than find().
