make sure you use proper ojbdc version for your oracle level and was level. detailed reuirement should be given in SystemOut.log if it doesn't match your config at the moment.
it may also mean that your database codeset may be wrong from the one expected by was. I'm not an oracle guy but in db2 it's common that you have to make some adjustments in codeset to work with WAS.
