Maintenant j'ai un autre probleme:
je veux affiché untableau qui contient des nom et prenom:
donc je fais appelle a une fonction qui retourne une liste :
Code:

1 2 3 4 5 6 7 8 9 10 public List<UserBean> listerTousLesUserBean() { List<UserBean> l= new ArrayList(); l.add(new UserBean(13213,0002,"man","paula")); l.add(new UserBean(19845,0007,"Vetter","Marco")); return l; }
lister.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 31 32 33 34 35 36 37 38 39 40 <%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <html> <head> <title>Add New User Form</title> </head> <body> <f:view> <h:dataTable var="userBean" border="1"> <h:column> <f:facet name="header"> <f:verbatim>Nom</f:verbatim> </f:facet> <h:outputText value="#{userBean.listerTousLesUserBean().get(0).name}"/> </h:column> <h:column> <f:facet name="header"> <f:verbatim>Prénom</f:verbatim> </f:facet> <h:outputText value="#{userBean.addUser.listerTousLesUserBean().get(0).prenom}"/> </h:column> </h:dataTable>
il m'affiche une erreur !!
voici l'erreur:
org.apache.jasper.JasperException: /listertous.jsp(25,0) The function listerTousLesUserBean must be used with a prefix when a default namespace is not specified
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)

Je te conseille de lire un peu la documentation avant de se lancer, y'a beaucoup d'exemples sur ce forum et sur le net en général de l'utilisation de dataTable.

Les expressions EL ce n'est pas du code java, on ne peux pas appeler des méthodes sur des listes, ça fonctionne en général comme ça:

Code:

<h:outputText value="#{bean.variable}" />

bean est le nom donné au bean géré par JSF et variable est un champ du bean avec des getter/setter.
