Can someone please help me understand why I am getting the exception below when trying to execute this query:

String sql = "select u.username, f.fname from user u, file f where f.OwnerID = u.ID";
SQLQuery query = session.createSQLQuery(sql);
query.addEntity("u", User.class);
query.addEntity("f", AppFile.class);


AppFile.hbm.xml:
<class name="beans.AppFile" table="FILE">
<id name="id" column="ID">
<generator class="native"/>
</id>
<property name="fSize"/>
<property name="fName"/>
<property name="vaultID"/>
<property name="ownerID"/>
<property name="status"/>
<property name="createdOn" type="timestamp" column="createdon"/>
<property name="modifiedOn" type="timestamp" column="modifiedon"/>
<property name="modifiedBy"/>



User.hbm.xml:

<class name="beans.User" table="USER">
<id name="id" column="ID">
<generator class="native"/>
</id>
<property name="userName"/>
<property name="firstName"/>
<property name="lastName"/>
<property name="emailAddress"/>
<property name="password"/>

</class>


Is it not possible to use the primary key of a table in such queries?
The ID column does exist in the database, the USer bean has getters and setters for Id which is defined as a Long.

The following query works just fine:
List result = session.createQuery("from User").list();

Here is the query as shown in Tomcat.

Hibernate: select user0_.ID as ID6_, user0_.id as id6_, user0_.userName as userN
ame6_, user0_.firstName as firstName6_, user0_.lastName as lastName6_, user0_.em
ailAddress as emailAdd5_6_, user0_.password as password6_ from USER user0_

Thanks for the help
