Extraire le clé primaire à partir d'une ligne d'un datatable

Bonjour , je developpe une entreprise application JEE avec netbeans 6.7 ,JSF et MySQL representant une interface web aux clients qui leurs permettent de s'inscrire au premier temps et de login et modifier leurs comptes ultérieurement .


Une de mes page est la page 'list' qui represente sous forme d'un datatable tout les clients avec un commandbutton delete et un command button edit devant chaque ligne .
Mais ,maintenant je suis face à un probléme .Quand je clique sur le bouton 'delete' (ou edit ) pour supprimer cette ligne ca marche uniquement si j'ai laissé la session ouverte cad si j'ai pas cliqué sur le 'logout' précédemment .

Si j'ai quitté la session en cliquant sur 'logout' ou si j'ai pas entré complétement à mon compte et je suis passé directement à la page 'list' , quand je clique sur le bouton , je trouve cet erreur :

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

type Rapport d'exception     Message   DescriptionLe serveur a rencontré une erreur interne () qui l'a empêché de remplir cette requête.   Exception   javax.servlet.ServletException: #{metier.update}: java.lang.NullPointerException   Cause racine   javax.faces.FacesException: #{metier.update}: java.lang.NullPointerException   Cause racine   javax.faces.el.EvaluationException: java.lang.NullPointerException   Cause racine   java.lang.NullPointerException   note Les suivis de pile complets de l'exception et de ses causes principales sont disponibles dans les journaux Sun GlassFish Enterprise Server v2.1.

---

Normalement ca vient du faite qu'il peut pas trouver le cle primaire 'login' de la ligne concernée .

La methode 'delete' par exemple est la suivante :

Code:

---

1 2 3 4 5 6 7 8 9 10 11

public String delete() { FacesContext context = FacesContext.getCurrentInstance();   Map map = context.getExternalContext().getRequestParameterMap(); login = (String) map.get("loginn");   cf.remove(c);   return "removed"; }

---

ou c est de type client et cf de type clientfacadelocale .

Le code concernant le commandbutton est le suivant :

Code:

---

1 2 3 4 5 6

<h:commandButton id="deleteclient" value="Delete" action="#{metier.delete}">   <f:param name="loginn" value="#{item.login}"/> </h:commandButton>

---

Une idée ? Merci.

Une idée ? Merci.

Si on pouvait déjà avoir le stacktrace de l'exception, on saurais ce qui est null et comment réparer ça.

Salut ,


Bon j'ai pas travaillé avant avec stacktrace , j'ai trouvé cet exemple dans ce lien

http://www.roseindia.net/java/java-g...e-string.shtml

est c'est ca qui convient .


Merci

tu fait simplement e.printStackTrace(), e étant ton exception. Et tu nous donne à la fois en entier ce que ca sort et le code qui concerne ce stacktrace.

Jai essayé de le faire de cette maniére

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

public String remove2() throws Exception {   try { FacesContext context = FacesContext.getCurrentInstance();   Map map = context.getExternalContext().getRequestParameterMap(); login = (String) map.get("loginn");   cf.remove(c);   } catch (IOException e) {   e.printStackTrace(); } return null; }

---

mais ca montre cet erreur :

Code:

---

exception java.io.ioexception is never thrown in body of corresponding try statement

---

devant la ligne

Code:

---

catch (IOException e)

---

c'est quoi qui est mal fait ?

de toutes facons ton exception est déjà mentionnée par JSF, donc elle doit déjà etre loggué quelque part. Quand à ton never thrown, c'est parce que IOException n'est pas une exception possible dans le code que t'as mentionné

Salut ,

y'a t'il donc pas une solution pour contourner ca ?

Merci d'avance

ben commence pas nous donner les stacktrace, il doit être quelque part dans les logs du serveur.

Salut ,

désolé mais j'ai pas compris ce que tu veut dire par

c'est parce que IOException n'est pas une exception possible dans le code que t'as mentionné .

Merci

tu n'a aucun code suceptible de lancer une IOException, donc le try catch est non seulement inutile mais une erreur. De toutes facons, dans ton cas, on a pas besoin de ce try catch pour ta nullpointerexception, on a juste besoin d'avoir le stacktrace de l'exception et normalement, ton JSF ou ton conteneur l'a déjà loggué quelque part. Dans tomcat, par exemple, tu le trouvera dans "logs/catalina.out"

Salut ,

moi je travaille avec Glassfish . Ou je trouve donc le stcktrace ?
Merci

d'après ce que je sais, glassfish utiliser un fichier "server.log" pour tout ce qui est System.out et System.err.

Salut ,

j'ai cherché j'ai trouvé ce fichier log appelé message dans le chemin C:\Users\NIDHAL\.netbeans\6.7\var\log

Le contenu est le suivant

ça ce sont les log de netbeans, ce qui nous intéresse, ce sont les logs de ton serveur glassfish. Souvent, quand tu lance dans un IDE ton conteneur J2EE, l'IDE s'arrange pour que les logs soient redirigés vers la console de l'IDE (en tout cas c'est le cas pour eclipse /tomcat). Regarde donc de ce coté là. Tu devrais y trouver des exception, dans lesquelle tu verra au minimum dans le stack des références à HttpServletRequest et à JSF (com.sun.jsf ou org.apache.myfaces suivant l'implémentation).

Qui a-t-il a cette ligne?

Ent.ClientFacade.remove(ClientFacade.java:31)

Salut ,

Normalement ca correspond à la ligne

Code:

---

cf.remove(c);

---

de la methode remove2


ou cf est de type ClientFacadeLocal et c est de type Client .

t'as vérifié que c n'est pas null? Quand à la ligne elle est bien dans c.remove, mais je demande le code à cette ligne 31.

Exactement ,

j'ai vérifier avec les System.out.println , j'ai trouvé que pour lui 'c' est null car 'login' encore est null pour lui . Le probleme maintenant est comment pouvoir récupérer le 'login' à partir de la ligne du datatble .

Concernant le code à la ligne 31 , j'ai pas compris exactement ce que tu cherche , car la ligne 31 dans mon code n'a rien à voir avec ca .

Merci

cette ligne 32 est la dernière de ton code qui manipule ton objet. C'est donc elle qui devrais s'assurer que c n'est pas null. En ce qui concerne ton problème, d'ou elle sort ta variable login? Quel est le lien entre ton login et c ?

Salut ,

la derniére ligne qui manipule l'objet c est la ligne

Code:

---

1 2	cf.remove(c);

---

Le lien entre le login et c :

c est de type client qui a comme clé primaire 'login' . La page liste affiche une lidte des clients dans un datatable . Devant chaque client , deux commandbutton , un pour la modification du profil du client , l'autre 'delete' pour supprimer ce client .

Normalement , pour supprimer le client , on doit connaitre son clé primaire (n'est ce pas ?) et c'est ca donc le lien entre c et login .

Ce que j'ai remarqué , que le 'login' n'a pas eté récupéré (null) ,
c'est pourquoi 'c' est de meme null ce qui implique cette erreur au niveau de la ligne

Code:

---

cf.remove(c);

---

c viens d'ou? Tu le récupère comment? (Du code svp)

Salut ,
Le code de la methode remove2 est le suivant :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13

public String remove2() { FacesContext context = FacesContext.getCurrentInstance();   Map map = context.getExternalContext().getRequestParameterMap(); login = (String) map.get("loginn");   c=cf.find(login);   cf.remove(c);   return "removed"; }

---

Pour récuperer 'c' j'ai fait la recherche avec le 'login' comme ca :

Code:

---

c=cf.find(login);

---

on peut voir dans tes balises JSF comment tu transfère ce paramètre loginn? PS: est-il normal qu'il contiennent deux n?

Salut,


Je le récupére comme ca :

Code:

---

1 2 3 4 5 6 7 8 9 10

<h:column>   <h:commandButton id="deleteclient" value="Delete" action="#{metier.remove2}">   <f:param name="loginn" value="#{item.login}"/> </h:commandButton>   </h:column>

---

tu peux nous montrer le html généré pour un de tes liens? Ou remplace par ça et dit nous si loginn est bien non null.:

Code:

---

1 2 3 4 5 6

<h:commandButton id="deleteclient" value="Delete (loginn= #{item.login})" action="#{metier.remove2}">   <f:param name="loginn" value="#{item.login}"/> </h:commandButton>

---

Salut ,


d'une part ca affiche loginn=h (ou h est le login) , donc item.login non null,

d'autre part le

Code:

---

System.out.println(login);

---

affiche un login null et l'rreur est le meme .(regarder la piece jointe)

Salut ,

tant que ca marche pour

Code:

---

loginn= #{item.login}

---

et ca marche pas pour le 'login' , normalement ca se bloque au niveau de la ligne

Code:

---

login = (String) map.get("loginn");

---

n'est ce pas ?

A partir du moment ou ton loginn est bien mis dans la requete (via f:param) je ne m'explique pas pourquoi tu ne le recois pas coté serveur.

Salut ,

normalement c'est cette ligne qui marche pas

Code:

---

1 2 3 4

<div class="bbcode_container"> <div class="bbcode_description">Code:</div> <hr /><code class="bbcode_code">c=cf.find<span class="br0">(</span>login<span class="br0">)</span>;</code><hr /> </div>

---

y'a t'il donc pas une autre methode pour contourner ca et récupérer autrement le item.login à partir de la pga 'list.jsp' ?

Merci

c'est pas ce code la qui marche pas, comme tu le dit toi meme le login que tu recupere dans login = (String) map.get("loginn"); est null, ou alors j'ai pas compris.

oui oui , désolé cé ca la ligne

Code:

---

login = (String) map.get("loginn");

---

Alors pas d'autre facon ?

tu ne dois pas recevoir un null à cet endroit la si t'as cliqué sur le bouton indiqué. Qu'est-ce que tu entends par "pas entièrement loggué" au début de ton post?

Désolé , mais j'ai pas trouvé cette citation

"pas entièrement loggué"

c'est ou exactement ??

le terme que t'as utilisé est "j'ai pas entré complétement à mon compte"

Ah ok ,

ce que j'ai voulu dire c'est que lorsque je (cad le client x ) entre à son compte et ne clique pas sur le bouton 'logout' pour fermer sa session , le 'c' et le 'login' du client x restent mémorisé (car j'utilise le session scope), de tel facon que lorsque on passe par la suite à la page 'list' , lorsqu'on veut supprimer n'importe quel client , c'est uniquement le client x qui est supprimé vu la ligne :

Code:

---

cf.remove(c);

---

Maintenant , si je passe directement à la page liste , ca marche pas .

d'après ton code, c dépend de la ligne, et non pas de l'utilisateur. D'après ton message, c serait l'utilisatur courant et ne dépendrait donc pas de la ligne. T'as un problème de logique quelque part là...

Si tu rajoute ce code:

Code:

---

1 2	login = (String) map.get("loginn"); System.out.println("le login est "+login);

---

Qu'est-ce que ca donne dans la console? null ou "h" ?

ca donne null,

cé ca , ce que je veut c'est que c dépend de la ligne (peut etre j'ai mal expliqué)

Je viens seulement de me rendre compte. Tu utilise un commandButton et non un commandLink :aie:. Le commandButton ne gère pas les paramètres (d'ou la réception du null). Utilise le commandLink et ça devrais passer :roll:

mais , dés le début ,j'ai essayé avec commandLink , mais lorsqsue je clique sur le commnadLink , rien ne change , càd que tout est statique cad comme si j'ai fait rien .(il n'y'a pas meme un erreur ) , meme le

Code:

---

System.out.println("le login est "+login)

---

n'affiche rien (meme pas null) ;
