Hi All,

I am having problem with sort mapping for comparator class which is not an inerr class in my class.
But for some reason I am getting the org.hibernate.MappingException: Could not instantiate comparator class exception for following mapping.

My comparator class is a simple java class:

my mapping for sort is as follows:
public class Money extends Comparable<Money> {

---other implementation code goes here

public int compareTo(Money money) {
return value.compareTo(money.value);
}
}

<map name="entries" table="bid_values" lazy="false" sort="com.app.type.Money" cascade="all">
<key column="id"/>
<index column="price"/>
<composite-element class="com.app.model.Entry">
<property name="volume" column="volume"/>
<property name="price" column="price"/>
</composite-element>
</map>

I dont see any reason for the excpetion. Can any please put some light on it.

any help appreciated!

cheers!!

A couple of things to consider
- is there anything about your Money class that could make it difficult to instantiate using reflection?
- a Comparator should provide a:

method, not the compareTo that you have shown in your code sample.
(You may have confused Comparator with Comparable)
