Multiple Kodo Datasources in WebLogic 8.1 using JCA - How?

Question

Greetings
I am trying to set up WebLogic (8.1) such that I can deploy a single Kodo
JCA connector but use it to access multiple data sources. Assuming that the
JCA adaptor has been deployed to the Server with a name and jndi key of
"kodo", I believe that the way to do it is to deploy a second copy of the
weblogic-ra.xml and ra.xml files and use an <ra-link-ref> tag to refer to
the primary deployed JCA adaptor. The second ra.xml has different kodo
config-property-values for connection URL, Username/password, etc from the
primary ra.xml.
This seems to work - to a point. Accessing the second "adaptor" ("kodo2")
does work and seems to link to the primary one, but the ra.xml
config-properties which are used appear to be from the primary deployment :(
not the second one as I hoped.
Can anyone point me in the right direction? Below is a copy of the
secondary weblogic-ra.xml file:
<!DOCTYPE weblogic-connection-factory-dd PUBLIC

Drew-
It should be possible to use two separate Kodo JCA configurations in the
same application server. Could you post your two configurations (without
the license keys, please) so we can take a look of the different places
where you are configuring the sequence table names? I suspect that there
might be a simple misconfiguration or type somewhere.

I think I have partially figured this out. Actually I shouldn't have ra.xml
in the second JCA adaptor, instead I can specify different config properties
in weblogic-ra.xml such as:
<map-config-property>
<map-config-property-name>Schemas</map-config-property-name>
<map-config-property-value>FRED</map-config-property-value>
</map-config-property>
I am still getting some weird behaviour though. For example, I currently
get an exception when trying to to an update because kodo2 tries to get the
sequence from the wrong schema, i.e.:
com.solarmetric.jdbc.ReportingSQLException: ORA-00942: table or view does
not exist
{prepstmnt 7569347 SELECT SEQUENCEX FROM MARY.JDO_SEQUENCEX WHERE PKX = ?
FOR UPDATE [reused=0]} [code=942, state=42000]
at
kodo.jdbc.schema.DBSequenceFactory.getNext(DBSequenceFactory.java:227)
Etc...
It should be getting the sequence from FRED (kodo2), not MARY (kodo).
Any tips about how to configure multiple kodo JCA properties in Weblogic 8.1
would still be very much appreciated.
Cheers!
