DB2 doesn't seem to support variables of type "byte" (they have to
be serialized), so it doesn't surprise me that DB2/400 doesn't either. If
you comment out the byte mapping in jaws.xml (thereby forcing bytes to be
serialized) and update the TimeStamp one to read Timestamp, can you then
run the dbtest successfully without altering the ejb-jar.xml file?
Thanks,
Aaron
