 Post subject: Could not instantiate comparator

Hi all,

I'm having problems running my DAO unit tests now that I've written a comparator class to sort a set in my entity:

Code:
/**
     * Returns all available transatlantic flights.
     * @return
     * @hibernate.set where="flightType='T'" inverse="true" cascade="all-delete-orphan"
     *                  sort="org.iom.sima.util.FeederComparator"
     * @hibernate.collection-one-to-many class="org.iom.sima.model.FlightInformation"
     * @hibernate.collection-key column="bookingId"
     */
    public Set getTransAtlanticFlights() {
        return transAtlanticFlights;
    }


I get the following error:

[junit] Exception in thread "main"
[junit] Test org.iom.sima.dao.ProFlightDAOTest FAILED


Note that when I run the actual application, the comparator works fine. It only fails for the unit tests.

I already tried putting the comparator class explicitly in the class path for the JUnit target to no avail.

Anyone know what's causing this problem?

Do you have a public/package level default constructor for the comparator? If not, then have one public/package level constructor for the same

That's not the problem. I have an implicit default constructor and anyway, the application does work. Its only the unit test that fails.

May be you did not look up for the DAO properly. If possible then put some of your JUnit code. that would help to look more into the problem

Hi,

i have the same problem. But only if i run the SchemaExport task. The application is running without such a problem.

Comparator class

Code:
package ecobill.module.base.hbm.sort;

import java.text.Collator;
import java.util.Comparator;

/**
* User: Romsl
*/
public class OrderPositionComparator implements Comparator {

    public OrderPositionComparator() {
    }

    /**
     * Collator
     */
    private Collator collator = Collator.getInstance();

    /**
     * @see Comparator#compare(Object, Object)
     */
    public int compare(Object o1, Object o2) {
        if (o1 instanceof OrderPositionComparable && o2 instanceof OrderPositionComparable) {
            Integer o1OrderPosition = ((OrderPositionComparable) o1).getOrderPosition();
            Integer o2OrderPosition = ((OrderPositionComparable) o2).getOrderPosition();

            return collator.compare(o1OrderPosition, o2OrderPosition);
        }

        return 0;
    }
}


the mapping declaration

Code:
<set name="articles" table="BASE_REDUPLICATED_ARTICLE" cascade="all-delete-orphan" lazy="false" sort="ecobill.module.base.hbm.sort.OrderPositionComparator">
    <key column="DELIVERY_ORDER_ID"/>
    <one-to-many class="ecobill.module.base.domain.ReduplicatedArticle"/>
</set>


and the whole exception tree
