[J2EE] Errore "404: File not found" nella servlet

[Uccio87]

Salve,

ho seguito alla lettera l'esempio: trigger java.
inseriti i vari link per testare l'applicazione ricevo come errore: Oops! This page appears broken. HTTP 404 - File not found.

come posso risolvere questo problema?
Grazie

Molto probabilmente hai censito male la servlet, l'errore 404 è data dal server quando trova associato ad un determinato URL una pagina o una servlet. Ricontrolla il web.xml dell'applicazione e l'indirizzo digitato nel browser.

Grazie per la risposta.
se inserisco come url: http://localhost/DBProcedures/ funziona se invece inserisco:

http://localhost/DBProcedures/Contro...ame=nomeUtente

http://localhost/DBProcedures/Contro...r=1&price=1330

http://localhost/DBProcedures/Contro...e&idpurchase=4

mi salta fuori l'errore 404.

Controllo la servlet e il web.xml.

Non riesco a risolvere il mio problema! mi sembra tutto ok!!!!

prova a postare il web.xml e la servlet in questione.

Domanda: ma tu hai direttamente il tomcat configurato sulla porta 80 (invcece della 8080) oppure passi per un apache tramite connettore ajp (o http) ?

Passo attraverso un apache!

Ecco appunto...quindi non è l'unica cosa da verificare, oltre al web.xml posta anche il httpd.conf o altri file di apache in cui puoi aver inserito delle configurazioni che possono influire

scusate per il casino
