hi, i am trying to do a simple thing without success!!! in my
web application (designed under the struts framework), i have a logon action
which check the username and password of a user, if it's ok i create and
store an object User with a session scope. i have a another item at my
menu wich enable a user to display his information (stored in the user
object), here is the code. theres is 3 files EditmonCompteAction wich
display the user information. User bean wich store information about the
user. MoncompteForm is the bean form used in the mapping-action. and
finally of course the
struts-config.xml <pre> EDITMONCOMPTEACTION *******************
* public class EditMonCompteAction extends Action
{ public ActionForward execute(ActionMapping
mapping,ActionForm form,HttpServletRequest request,HttpServletResponse
response)throws Exception { //Recupere l'utilisateur 'user' en cours 
User user = (User)
(request.getSession()).getAttribute(Globals.USER_KEY); if (user
== null) return mapping.findForward("logon"); //Creation du form bean "moncompteForm" s'il n'existe
pas if (form==null) { //Creation du from-bean form =
new MoncompteForm(); //Ajout a la
requets ou session selon l'attribut "scope" de
<action-mapping> if ("request".equals(mapping.getScope())) 
request.setAttribute(mapping.getAttribute(),form); else 
request.getSession().setAttribute(mapping.getAttribute(),form); } 
 //Copie de user vers form 
MoncompteForm moncompteForm = (MoncompteForm) form; 
PropertyUtils.copyProperties(moncompteForm, user); //Attache un synchroniser token pour eviter le double
posting saveToken(request); //Renvoie vers moncompte return
mapping.findForward("moncompte"); }
 } </pre> STRUTS-CONFIG.XML ***************** <pre> .... <global-forwards> 
<forward name="index" path="/index.jsp"/> <forward name="logon" path="/logon.jsp"/> <forward name="acceuilUser" path="/acceuilUser.jsp"/> <forward name="moncompte" path="/moncompte.jsp"/> 
</global-forwards> ......  <action path="/editMonCompte" type="eshop.actions.EditMonCompteAction" 
attribute="moncompteForm" 
scope="request" validate="false"/>
 ...... </pre> MONCOMPTEFORM ************* <pre> public
 class MoncompteForm extends ValidatorForm{ .... 
private String nom; private String prenom; 
private String password; .... public void
setNom(String nom) {this.nom=nom;} public void
setPassword(String password) {this.password = password;} 
public void setPrenom(String prenom)
{this.prenom=prenom;} .... public String getNom()
{System.out.println("entr?e dans
MonCOmpteForm.getNom");return nom;} public String
getPassword(){return password;} public String getPrenom()
{return
prenom;} } </pre> USER **** <pre> public
class User { ... private String nom; private
String prenom; private String password; ... public
void setNom(String nom) {this.nom=nom; public
void setPassword(String password) {this.password =
password;} public void setPrenom(String prenom)
{this.prenom=prenom;} .... ublic String getNom() {return
nom;} public String getPassword(){return password;} 
public String getPrenom() {return
prenom;} } </pre> when the editMonCompte.execute() methode is
performed, i have display the content of the form, and its property
reflected those of the object USER, but nothing is displayed in the
moncompte.jsp, which use ofcourse the struts html taglib (html:text,
html:submit....) i don't understand what's wrong with my
code thanks for your help.

Hello,

a few things, I believe this is unnecessary:

//Creation du form bean "moncompteForm" s'il n'existe pas
if (form==null) {
//Creation du from-bean
form = new MoncompteForm();
//Ajout a la requets ou session selon l'attribut "scope" de
<action-mapping>
if ("request".equals(mapping.getScope()))
request.setAttribute(mapping.getAttribute(),form);
else
request.getSession().setAttribute(mapping.getAttribute(),form);
}

as long as your struts-config is set up properly, struts should
automatically create a form bean for you and place it in the
appropriate scope..

however I don't think your action-mapping is correct.. it should be:

<action path="/editMonCompte"
type="eshop.actions.EditMonCompteAction"
name="moncompteForm"
scope="request"
validate="false"/>

I believe you used 'attribute' instead of 'name'.. check out
strutsconsole (http://jamesholmes.com/struts/) it will validate your
struts-config file for you..

give that a try and see what happens..
