Aide pour richfaces

bonjour je me met à jsf et j'ai commencé par cet exemple qui ne fonctionne pas
quelqu'un pourrait bien m'expliquer pourquoi?

voici mon web.xml:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 <?xml version="1.0"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>test</display-name> <description>richfaces test</description> <context-param> <param-name>org.richfaces.SKIN</param-name> <param-value>blueSky</param-value> </context-param> <filter> <display-name>RichFaces Filter</display-name> <filter-name>richfaces</filter-name> <filter-class>org.ajax4jsf.Filter</filter-class> </filter> <filter-mapping> <filter-name>richfaces</filter-name> <servlet-name>Faces Servlet</servlet-name> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> <dispatcher>INCLUDE</dispatcher> </filter-mapping> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping> <login-config> <auth-method>BASIC</auth-method> </login-config> </web-app>
la mon faces-config.xml:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 <?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd" version="1.2"> <managed-bean> <managed-bean-name>helloBean</managed-bean-name> <managed-bean-class>rich.HelloBean</managed-bean-class> <managed-bean-scope>request</managed-bean-scope> <managed-property> <property-name>name</property-name> <property-class>java.lang.String</property-class> <value/> </managed-property> </managed-bean> </faces-config>
mon bean:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 package rich; public class HelloBean { private String name; public HelloBean(){ name=" Nobody"; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
J'ai deux pages la pricipale:

--hello.jsp--
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%> <%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%> <%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%> <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Ma page richfaces</title> </head> <body> <f:view> <a4j:form> <rich:panel header="Test RichFaces" style="width: 350px"> <h:outputText value="Your name: " /> <h:inputText value="#{helloBean.name}" > <f:validateLength minimum="1" maximum="30" /> </h:inputText> <a4j:commandButton value="Get greeting" reRender="greeting" /> <h:panelGroup id="greeting" > <h:outputText value="Hello, " rendered="#{not empty helloBean.name}" /> <h:outputText value="#{helloBean.name}" /> <h:outputText value="!" rendered="#{not empty helloBean.name}" /> </h:panelGroup> </rich:panel> </a4j:form> </f:view> </body> </html>
et l'index
--index.jsp--
Code:

1 2 3 4 5 6 7 8 9 10 11 12 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Refresh" content= "0; URL=hello.jsf"/> <title>Insert title here</title> </head> <body> Démarage de l'application... </body> </html>
Bien sur les librairies que j'utilises sont:

so c'est koi mon problème?????
Merci de vous y interessé.

Bonsoir,
bon j'ai tester ton exemple et ça marche parfaitement.
:roll: vraiment j'ai voulu t'aider mais je ne vois pas ou est le problème. en tous cas ton exemple marche.

Au secour

Merci monalisa_smile moi meme je suis plutot depassé. Mais s'il te plait tu peux me donner ta configuration. moi comme je l'ai dis je suis sous eclipse ganymede,tomcat 6, et iexplorer 6. Et le truc c'est que je comprend rien au message d'erreur.

Hello

Au fait dans le cas ou tu utiliserais tomcat,tes librairies sont partagées(dans tomcat) ou se trouvent dans le classpath de l'application?

Sorry

le problème c'est que j'ai mal nommé le fichier faces-config.xml!!!!
Merci pour l'aide.

désolée de ne pas avoir répondu avant, moi aussi j'ai la meme configuration. heureuse que ta pu régler ton problème et je te souhaite bon courage.
