This means, that the character set you specified on connecting to the
database (well, you might haven't, but driver selected by the default
ISO8859_1) does not match the encoding used for column definition and
InterBase/Firebird is not able to perform conversion. So, you either
add your encoding to the connection parameters using the
FBWrappingDataSource.setConnectionRequestInfo(...), or edit the
FBManagedConnectionFactory constructor to include your encoding, or
wait couple of days until I finish code that will allow you to
specify the character encoding in the connection parameters.
