I have a webapp which runs a networked Derby server. I want to be able

which works fine. However, when I try to open a second connection with
IJ it gives me this response:
ij> connect '/foo/db;dataEncryption=true;bootPassword=xyz';
ERROR XJ040: Failed to start database '/foo/db', see the next

Is there something I'm missing here?
Hi John,
Looks to me like you are trying to access, or more specifically boot,
the database with the embedded driver. This won't work since the network
server has already booted the database [1].
The only change required should be to add the host name to the
connection URL (localhost?), i.e. something like
"jdbc:derby://localhost[:port]/db[;attributes]". You will then get two
(or more) connections to the database, all using the client driver and
going through the network server.
Regards,

[1] I'm assuming a connection to the database has already been made
through the network server. If you connect with the embedded driver
first, the connection through the network server will fail instead.
TIA,
