Configurazione Servlet [URGENTE]

[Sara79]

Ho scaricato da questo link:
http://jakarta.apache.org/site/binindex.cgi
il tomcat jakarta 5.0.19. ho fatto tutto quello che c'è scritto sul file di configurazione ma non funziona nulla . Era quello giusto che dovevo scaricare??
Se qualcuno sa come farlo andare.... è urgente. Grazie. Sara.

Io ho scaricato:
- jwsdp-1_3-windows-i586 (da java.sun.com)
- jakarta-tomcat-4.1.29

Il seguente link mi ha risolto tutti i problemi di configurazione:

Ciao!!!

[Sara79]

ti ringrazio tanto per il link. mi servirà di sicuro. grazie ancora!

[Sara79]

L'ho provato in tutte le salse e...funziona.

Cosa c'è che non va lì?

[cn73]

Cos'è che non comprendi Sara?p.s usa il tago code quando scrivi codice

[Sara79]

Nel senso...lo compilo tranquillamente e nn mi da errori ma nn riesco a vederlo!
Dopo che ho installato il tomcat che comando lancio per vedere la mia applet che gira??

[cn73]

Il tuo Server Tomcat ti fornirà un indirizzo con cui accedere all'applet. Se è sulla setssa macchina da browser dovrai collegarti a http://localhost:numero_porta:/path_dell'applet

[Sara79]

Quando io ho il mio file .class devo fare un file html che la richiami?...anche se mi pare inutile visto che ho fatto l'interfaccia grafica...

[Sara79]

ho bisogno di delucidazioni...ho provato a lanciare la servlet ma proprio nn mi parte.

ho usato: http://localhost:8080:/locazione servlet

qualcuno mi fa un esempio così magari vedo dove sbaglio?! Tnx

Intanto togli i : dopo 8080, poi per installare una applicazione web su Tomcat devi creare una particolare struttura di directory, dimmi cosa hai fatto e posso cercare di vedere dove sta l'errore.

Per lanciare l'applicazione come hai scritto deve esistere una cartella "locazione" all'interno della cartella TOMCAT_ROOT/webapps, e deve esserci il file index.html, altrimenti devi chiamare esplicitamente il file che ti interessa, tipo http://localhost:8080/locazione/file.htm

[Sara79]

Innanzi tutto ho installato il mio tomcat e cambiato alcune opzioni per abilitare l'invoker delle servlet come mi era stato consigliato. a questo punto ho provato in tutte le salse.
La mia servlet ha un'interfaccia grafica sua, senza file html. quando nella barra di inserimento dell'url scrivo l'indirizzo del mio file, quindi, http://localhost:8080/percorso_file/nome_file mi da un errore di http404 e dice che la risorsa nn è disponibile.
cosa devo fare? c'è qualche altra impostazione da abilitare?? (chiedo scusa per l'ignoranza)
il file .class lo devo mettere dentro la sottocartella WEB-INF di ROOT nel tomcat?

[gabriele81]

Puoi postare il file web.xml della tua applicazione? magari hai scritto qualcosa di sbagliato lì dentro.

Ti ricordo che essenzialmente devi fare una struttura di directory così:

TOMCAT_ROOT/webapps
    |
    |__ nome_applicazione (con dentro eventuali file html, jsp ecc.)
                  |
                  |__ WEB-INF (con dentro il file web.xml)
                             |
                             |__ classes (con dentro i .class della tua applicazione)

Poi sotto WEB-INF ci possono stare altre cartelle tipo lib per eventuali librerie di connessione a db ecc.

[Sara79]

questo è il file web.xml che sta dentro la cartella conf del tomcat.

io nn ho fatto altro che togliere il commento nella parte:

<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/* </url-pattern>
</servlet-mapping>

Nn riesco proprio a capire come fare a lanciarlo. PLEASE HELP....SONO ALLE STRETTE!!!

[Sara79]

allora.....ho provato ancora ma mi dice:

"HTTP Status 404 - /modulo/WEB-INF/classes/JAMail

--------------------------------------------------------------------------------

type Status report

message /modulo/WEB-INF/classes/JAMail

description The requested resource (/modulo/WEB-INF/classes/JAMail) is not available.


--------------------------------------------------------------------------------

Apache Tomcat/5.0.19"

ora, supponendo che io abbia il mio file nel seguente percorso:
C:\Programmi\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\modulo\WEB-INF\classes

cosa devo scrivere nel percorso del localhost???

http://localhost:8080/ ..... poi?

[gabriele81]

Ti avevo chiesto di postare il web.xml della TUA applicazione, non di Tomcat...per il momento ricommenta il pezzo che avevi scommentato.

Perchè il tuo file l'hai copiato lì? Ti conviene fare una tua applicazione web e mettere tutto lì.

Ad esempio...vediamo se stavolta riesco a farmi capire...
Hai una servlet che si chiama JAMail, giusto? Quindi avrai anche un file che si chiama JAMail.class da qualche parte.

Ora, nel tuo caso devi creare la tua directory (l'avevi chiamata modulo?) così:

C:\Programmi\Apache Software Foundation\Tomcat 5.0\webapps\modulo

Quindi all'interno di modulo metti eventuali file html (se non ce l'hai non ci metti niente) e crei la dir WEB-INF.
All'interno di WEB-INF devi mettere un file web.xml fatto così:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

</web-app>

Fai copia-incolla di questo codice nel notepad e salva il file come web.xml, quindi copialo dove ti ho detto.

All'interno di WEB-INF fai la cartella classes e lì ci metti i .class

A questo punto avvia Tomcat e con un browser vai su http://localhost:8080/modulo/JAMail

Se nel file web.xml all'interno dei tag url-pattern ci metti qualcosa di diverso, ad esempio se invece di /* ci metti /servlet/* per lanciare la tua servlet devi scrivere http://localhost:8080/modulo/servlet/JAMail
