I would say that the size of the column that is supposed to be the
primary key is greater than allowed in Firebird (correct me if I am
wrong, but that's 128 bytes). Check the deployment descriptors and
type mapping, probably you will have to define the custom field size
in jaws.xml (is it still jaws.xml? my last jboss was 2.2.1).
