I do not know what an "fqcn" is. I am running the latest Derby release,
10.8.1.2. The code pasted in below works great in the dev environment
(IntelliJ Idea), but the same code packaged in a jar cannot find the driver
with CLASSPATH set correctly.
public static Connection getConnection()
{
Connection c = null;
try
{ // The connectionURL is "jdbc:derby:EMDatabase;create=true
"
c = DriverManager.getConnection(connectionURL);
c.setAutoCommit(false);
}
catch (Throwable e)
{
log(3, "Unable to connect to " + dbName + ": " + e.getMessage());
stopDBMS();
System.exit(3);
}
return c;
}

Can you try specifying the driver as a fqcn? If that doesn't solve the issue
please paste relevant code around how you load the driver and obtain a
connection.
