This is type 4 JCA-JDBC driver (JayBird 1.0) for Firebird 1.0 (and
seems to work with IB 6.0.x too).

For IB 6.5 you have to use InterClient 2.5 that is shipped with
server, for IB 7.0 you have to use either InterClient 2.5 or
InterClient 3.0.

This group is main place for discussions about JayBird. For
InterClient Borland's newsgroups will be better choice.
