gds32.dll is in SYSTEM32 dir, jaybird ist not finding it, even not in my
working dir.
i have to use fbclient.dll in my working dir. (it was a typing error from me
in my first message)
and my app finds the jaybird.dll only in the working directory, not in any
other directory, although
it is in the java.library.path.

I have to write "local" not "LOCAL". "LOCAL" is not working.
i get unknown host LOCAL

Problem with local mode:
I get a deadlock when i have 2 concurrent connections, this seems to be a
bug in the driver.
(my appserver is getting the connections and doing db-selects for my rmi

With embedded-mode everything is working.
