The SQLState indicates that the server was not able to boot the database. Look in the server-side derby.log to see if there is a detailed error message describing why the boot failed.

Hi,

Sorry for the late answer but I lost your reply.

Two tests:

I have a database updated to version 10.12.1.1, the server is running with
the 10.12.1.1 too and the client is using 10.12.1.1 too, the connection is
OK, I can use this setup.

But another test:
still the same database updated to version 10.12.1.1, the server is running
10.15.2.0 so a newer version and the client is using 10.12.1.1: I have
problems in this case the client can't connect to the database with this
error:

Caused by: org.apache.derby.client.am.SqlException: DERBY SQL error:
ERRORCODE: 40000, SQLSTATE: XJ040, SQLERRMC: Impossibile avviare il
database '/home/user/some_db_path/' con il caricatore di classi
jdk.internal.loader.ClassLoaders$AppClassLoader@277050dc. Per i dettagli,
vedere l'eccezione successiva.::SQLSTATE: XBM0C

Thanks for the help

I'm not aware of client-server version incompatibilities. Have you
done any experiments with different versions?

Hi,

using derby with network server setup is there any problem if the server
and the client are running on different java versions?
Still on this, considering the database created/updated with the apache
derby version that the client uses, is there any problem if the server will
use a newer version of apache derby?
Thanks for the help
