Hi,
I would like to map a Vector of strings into a single VACHAR column.
According to the documentation OJB handles Vectors itself.
I added a field descriptor:
<field-descriptor id="6" name="stringEntries" column="stringEntries"
jdbc-type="VARCHAR"/>
The getter/setter return a List or Vector (tried both)
Storing is fine, the vector contains strings and these are stored as e.g.
[Deutsch, Englisch]
Lookup however fails with IllegalArgumentException i.e.
[org.apache.ojb.broker.util.sequence.SequenceManagerFactory] INFO: Use
sequence manager class: class
org.apache.ojb.broker.util.sequence.SequenceManagerHiLoImpl
[org.apache.ojb.broker.accesslayer.AbstractPoolableConnectionFactory] INFO:

Source)
Any ideas where I should look further? May this not be possible, or may
this require a special FieldConversion?
Thanks for any suggestions,
Stefan Schl�sser
