Ciao,ho installato Tomcat alla versione 5.5.20 su server unix, eh ho realizzato una webapp che utilizza come database, mysql alla versione 4.
Funziona tutto egregiamente, solo che tutte le mattine che rientro nella mia applicazione ricevo il seguente errore... Soluzione: rilanciare la webapp dal pannello manager.
