Programmer - Hibernate HQL with interfaces

Programmer Question

According to this section of the Hibernate documentation I should be able to query any java class in HQL



http://docs.jboss.org/hibernate/core/3.3/reference/en/html/queryhql.html#queryhql-polymorphism



Unfortunately when I run this query...



"from Transaction trans where trans.envelopeId=:envelopeId"


I get the message "Transaction is not mapped [from Transaction trans where trans.envelopeId=:envelopeId]".



Transaction is an interface, I have to entity classes that implement it, I want on HQL query to return a Collection of type Transaction.
