Please help!!!

First, I am using Hibernate 2.0.3 and Spring.

I have a interface called PaymentType which has 2 implementing classes- CreditCardPaymentType and EmailPaymentType. I am able to persist new PaymentTypes without issues; however, when associating a PaymentType to another object (Registration), I receive the following exception:

No persister for: com.demandsolutions.merovingian.payment.entity.PaymentType; nested exception is: net.sf.hibernate.MappingException: No persister for: com.demandsolutions.merovingian.payment.entity.PaymentType

Registration.java
------------------------
public class Registration extends BaseEntityObject {
private PaymentType paymentType;

// other variables and methods......

// Hibernate Mappings declared in supplementary file!
public PaymentType getPaymentType() {
return this.paymentType;
}

public void setPaymentType(PaymentType paymentType) {
this.paymentType = paymentType;
}

}

Registration.hbm.xml
--------------------------------
<hibernate-mapping>
<class name="com.demandsolutions.merovingian.conference.entity.Registration" table="registration" dynamic-update="true" dynamic-insert="true" >
// other declarations
<any name="paymentType" meta-type="class" id-type="long">
<column name="PAYMENT_TYPE_CLASS"/>
<column name="PAYMENT_TYPE_ID"/>
</any>
</hibernate-mapping>



Any and all help is appreciated! Thanks in advance!

I am posting my mapping files in hopes that someone can help me find my problem.

Once again, PaymentType is an interface. CreditCardPaymentType is an abstract class extended by multiple class. They are marked as subclasses.

Thanks for the help!

Yes, but how does the exception actually occur?? Java code? FULL stack trace?

OK. It's now absolutely obvious I should not have asked this question on 2 hours of sleep over a period of 40 hours ;)

Anyways, this problem is occuring when I tried to load a PaymentType object. I am calling:
this.getHibernateTemplate().load(clazz, serializable);
where clazz = PaymentType.class & serializable = id of paymentType.

I believe this has to do with not having a mapping file for PaymentType.class. Am I right?

Correct. So use a query:
