Hi Björn,
is this the whole stack trace? Your mapping seems ok. Did you include
the mapping for the HL-sequence (see repository_internal.xml)?
http://db.apache.org/ojb/repository_internal.xml.txt
Does your test pass with the in-memory sequence-manager?

hello list,
i've used ojb several times before, but now i am in trouble with ojb.
I have the following problem. I am using ojb in cocoon try to store
Objects from a flow controller.
If I store my Object to database, I get a PersistenceBrokerException:
Can't generate primary key values for given Identity .
I am using Java5 and the HSQLDB shipped with cocoon. My mapping looks like:
<class-descriptor class="de.rim.model.Kunde" table="KUNDE">
<field-descriptor name="id" column="ID" jdbc-type="INTEGER"
primarykey="true" autoincrement="true">
<field-descriptor name="vorname" column="VORNAME"
<field-descriptor name="adresse" column="ADRESSE" jdbc-type="VARCHAR"/>
<field-descriptor name="plz" column="PLZ" jdbc-type="VARCHAR"/>
<field-descriptor name="ort" column="ORT" jdbc-type="VARCHAR"/>
</class-descriptor>
i tried it also with sequence-names, changing to postgres
