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.
