[JSP]: File "web.xml" non corretto

[gbattine]

Salve ragazzi,
avrei bisogno di un aiuto. Dovendo realizzare un'applicazione web che tra le tante funzionalità deve offrire quella dell'upload di un file ho trovato un articolo di un certo Andrei Cioroianu che spiega come realizzare l'upload con JSF e Myfaces.
Il problema è che quando provo ad importare nel mio ambiente di sviluppo (Eclipse SDK versione 3.1.2) il web.xml di questa applicazione che ho scaricato ho il seguente errore:

Web descriptor file is corrupted: The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".:56:11.

Il web.xml è il seguente...potete aiutarmi per favore?
Considerate che sono alle primissime armi....

<?xml version="1.0" encoding="UTF-8"?>

lo spiega il messaggio
filter e filter-mapping devono essere prima di servlet

Grazie Floyd.......
Ho risolto il problema ma ora ne ho un altro.
Dopo vari errori a livello di compilazione (per fortuna risolti) sono riuscito ad avviare la mia applicazione. Il problema è che quando provo a caricare un file per l'upload ho un messaggio di errore di eclipse:

HTTP Status 500 -

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

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: Filter execution threw an exception


root cause

java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUpload
org.apache.myfaces.webapp.filter.ExtensionsFilter. doFilter(ExtensionsFilter.java:114)


note The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs.


Come posso risolverlo?
Vi posto il web.xml , il faces-config.xml e MyBean.java

Grazie

di nuovo il messaggio spiega il problema
non trova la classe org.apache.commons.fileupload.FileUpload
scarica il jar da [http://jakarta.apache.org/commons/fileupload/]qui[/url] e copialo in $webapp/WEB-INF/lib dove $webapp è la root della webapp

[cozzalonero]

io ho lo stesso tipo di problema, ecco l'errore che mi esce

The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)"


questo è il mio web.xml
