"No persister found" _only_ from session.get

Hibernate version:
2.1.6
Mapping documents:

Code:

<class name="com.acme.Account" table="Account">
  <id name="id_" column="id" type="long" unsaved-value="0" access="field">
    <generator class="identity"/>
  </id>
  <property name="name" column="Name" type="string" not-null="true"/>
  <property name="description" column="Description" type="string"/>
</class>

And Account extends IAccount which is an interface not declared anywhere in the mapping document. The intended strategy is table-per-concrete-class.

If I use session.get(IAccount.class, someId), I get the "No persister for: com.acme.IAccount" error.

However if I do

Code:

Query query = createQuery(session, "from " + IAccount.class.getName() + " as account where account.id=?");
query.setParameter(0, new Long(someId));
query.list();

I get a list containing one Account object back which is fine for me.

Why does it work in one way but not in the other?
Thanks.

because queries are polymorphical and get is not.
