Subject Re: [Firebird-Java] Re: Firbird thread safe?

In that case, why did I get this error? Pls see my earlier email about test results.
Without sync read/write method, Access too does throw exceptions as the number of
threads increase. But when read/write method is synchronizd, no exception is thrown
with Access. But Interclient throws too many exceptions with or without sync the
read/write method. What does it mean?

Where can I get type 4 driver? Is it different than Interclient?
