Hello Roman,

you asked what we used before:

It was the Firebird 1.0.2 and the old interclient.

The first connection is obtained by

DriverManager.getConnection (connectionUrl,
connectionUser,connectionPassword);

If the second connection is opened by

connection=DriverManager.getConnection(getURL(), "sysdba", "masterkey");

it succeeds.

But if the following code is used

info.put ("user",getUser ());
info.put ("password",getPassword ());
info.put ("charSet", "UTF8");
DriverManager.getConnection(getURL(), info);

it fails with the given message.

Thanks in advance for your advice.

Andreas
