Is this correct?
My map:
<class-descriptor class="com.microremedies.pm.persist.AccountImpl"
table="ACCOUNT" proxy="dynamic">
<field-descriptor name="uid" column="uid" jdbc-type="BIGINT"
primarykey="true" autoincrement="true"/>
<field-descriptor name="name" column="name" jdbc-type="VARCHAR"/>
<field-descriptor name="parentAccountID" column="parentAccountID"
jdbc-type="INTEGER" access="anonymous"/>
<field-descriptor name="ojbConcreteClass" column="ojbConcreteClass"
jdbc-type="VARCHAR"/>
<reference-descriptor name="parentAccount"
class-ref="com.microremedies.pm.persist.Account">
<foreignkey field-ref="parentAccountID"/>
</reference-descriptor>
<collection-descriptor name="subAccounts"
element-class-ref="com.microremedies.pm.persist.Account">
<inverse-foreignkey field-ref="parentAccountID"/>
</collection-descriptor>
</class-descriptor>
<class-descriptor class="com.microremedies.pm.persist.Account"
table="ACCOUNT">
<extent-class class-ref="com.microremedies.pm.persist.AccountImpl"/>
</class-descriptor>
when I query for Account.class I get this stack trace:
