Lettura dtabase dbf applicazione web

[mdegiova]

salve
sto realizzando una piccola applicazione web per la lettura di database formato dbf, sul mio pc non da problemi ma quando la carico sul server ARUBA la console JAVA mi da il seguente messaggio:

Potete dirmi perché e come posso risolvere.

Grazie mille

La prima riga dell'eccezione è piuttosto chiara: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "accessClassInPackage.sun.jdbc.odbc")

Com'è fatto il file di policy?
Aruba ti permette l'accesso al db?

Non ho ancora chiaro di cosa si tratta come file policy!
puoi spiegarmi cosa è e come e dove va costruito?
Aruba in asp e php non mi da problemi come accesso a dbf, infatti prima ho provato costruendo una simile operazione con gli stessi indirizzi delle cartelle del server in asp e php, ho verificato il funzionamento, ora sto passando a java.
