[Java] Applet e MySQL

[Marco_Frigerio]

una sola domandina... :gren:

Un Applet non può accedere e scrivere sui files... e fin qui ok!

ma può accedere ad un Database? in lettura e scrittura??? no perchè sto cercando di connettermi da mezz'ora ad un db MySQL sulla mia macchina, solo che un'applicazione va, mentre l'Applet no...



Grazie a tutti!

risolto: sulla guida in linea dei JDBC c'è scritto:

"I'm trying to use MySQL Connector/J in an applet and I get the following
exception:

SQLException: Cannot connect to MySQL server on host:3306. Is there
a MySQL server running on the machine/port you are trying to connect to?
(java.security.AccessControlException)
SQLState: 08S01
VendorError: 0

What's wrong?"

Resolution:

Applets can only make network connections back to the machine that the
webserver that served the .class files for the applet. This means that
mysql must run on the same machine (or you must have some sort of port
re-direction) for this to work. This also means that you will not be
able to test applets from your local filesystem, you must always deploy
them to a webserver.

beh ciao a tutti!!!
