I found out how to solve this problem. iBATIS permits custom type handlers to be registered. So in my sqlmap-config.xml file I added this:

And then added this class which implements the iBATIS TypeHandlerCallback interface:

// corrected getResult()/setParameter() to correctly deal with when value is null
public class CustomDateHandler implements TypeHandlerCallback {
    @Override
    public Object getResult(ResultGetter getter) throws SQLException {
        final Object obj = getter.getTimestamp();
        return obj != null ? (Date) obj : null;
    }

    @Override
    public void setParameter(ParameterSetter setter,Object value) throws SQLException {
        setter.setTimestamp(value != null ? new Timestamp(((Date)value).getTime()) : null);
    }

    @Override
    public Object valueOf(String datetime) {
        return Timestamp.valueOf(datetime);
    }
}

Whennever I need to map an Oracle DATE I now describe it like so:
