according to dtd i should write either extent or field-descripto 
elements  -

in the second part a "extent-class*" declaration is defined too. The 
first part mean that at least an extent-class definition is needed.

<!ELEMENT class-descriptor

I saw ReferenceTest test worked with OJB 1.0.1 too, with a different 
mapping of the interface. Did you tried to declare the 
reference-descriptor and fk-field in the interface class mapping too?

e.g.
Class RefObject is an interface
<class-descriptor class="org.apache.ojb.broker.ReferenceTest$RefObject">
        <extent-class 
class-ref="org.apache.ojb.broker.ReferenceTest$ObjA"/>
        <extent-class 
class-ref="org.apache.ojb.broker.ReferenceTest$ObjB"/>
        <extent-class 
class-ref="org.apache.ojb.broker.ReferenceTest$ObjC"/>

        <field-descriptor
             name="fkId"
             column="FK_REF"
             primarykey="false"
             jdbc-type="INTEGER"
            access="anonymous"
        />
        <reference-descriptor
            name="ref"
            class-ref="org.apache.ojb.broker.ReferenceTest$RefObject"
            proxy="false"
            auto-retrieve="true"
            auto-update="true"
            auto-delete="false">
                <foreignkey field-ref="fkId"/>
        </reference-descriptor>
    </class-descriptor>
If this doesn't work, try the mapping mentioned by Tom.

I'm using 1.0.1 version
ojb doesnt produce exception but it generates
SELECT A0.GROUP_ID,A0.ID FROM USER A0 WHERE A0.GROUP_ID = ?
instead of:
SELECT A0.GROUP_ID,A0.ID FROM USER A0, group1 a1 WHERE A0.GROUP_ID 
= a1.id and a1.manager_id=?

AFAIK Jakob fixed some bugs in conjunction with query references. So 
I recommend to give upcoming OJB 1.0.2 from OJB_1_0_RELEASE branch a 
change.

great!
i look forward to this release
i hope it'll solve my problem ;)
