> Hello,
> I'm trying to implement the custom authentication provider facility of Derby and am constantly hitting against a ClassNotFoundException.
> I created a DB on a Derby server running in ssl mode basic with no security manager. The DB is created with the following properties : 
>         CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.connection.requireAuthentication', 'true')
>         CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.defaultConnectionMode', 'noAccess')
>         CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.propertiesOnly', 'true')
>         CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.authentication.provider', 'lab.DerbyAP')
> derby.authentication.provider points to the custom class lab.DerbyAP, which is in a jar file on the server and in the classpath of the script starting the server (see attachement).
> When the DB is created, an authorized user can connect normally.
> If the server is shutdown and started again, no one can connect again. The database can't be booted on account of the custom class lab.DerbyAP not being found, though it is present and in the classpath.
> I attach also derby.log and sysinfo output or details.
> It seems that the server can't find at all a class in the classpath, or the classpath 'inside' the server does not reference the class.
> I tried also using the derby.database.classpath property after installing the jar file containing the custom class using sqlj.install_jar, but to no avail. The ClassNotFoundException still gets fired.
> I can't see what I'm missing, it smells like a single simple point but after three days researching the problem... it's getting long !
> Please advse.
> Thank you.
