Dear All,
Could someone help me to access my mysql database from an applet with
mm.mysql.jdbc-1.2c?
The problem is that when trying to access a mysql database from an
applet using Netscape it get an AppletSecurityException (described at
end of this message). But the mm.mysql.jdbc-1.2c documentation says that
"it allows Java developers to make connections to MySQL servers from
both Java applications and applets", so I don't understand what is
wrong. The same piece of code works nice if running as an application.
Cheers, Paulo Mora de Freitas.

'aldebaran.in2p3.fr' with origin from 'local-classpath-classes'.

Is there a MySQL server running on the machine/port you are trying to
connect to? (netscape.security.AppletSecurityException)
SQLState: 08S01
