Make sure all of the names in the zone file are relative to the domain, and
then specify the same name in the "filename" attribute of the "zone"
statement.  To refer to the domain itself in the zone file, use '@',
e.g. the file common.db could contain:

@ IN SOA ...
  IN NS ns1.company.com.
  IN NS ns2.company.com.
  IN MX 10 mail

box1 IN A 1.2.3.4
www IN CNAME box1

Then in named.conf:

zone "domainname.org" {
  type master;
  filename "common.db";
};
zone "domainname.com" {
  type master;
  filename "common.db";
};
