Si tu mets ça à true :
(balise foreach)
<rtexprvalue>false</rtexprvalue>

**wiss20000** · 19/04/2007, 10h48

merci mais le problème persiste

**the_ugly** · 19/04/2007, 11h00

Tu as relancé Tomcat après avoir modifié ta tld?

**wiss20000** · 19/04/2007, 11h12

oui

**the_ugly** · 19/04/2007, 11h27

Ca vient de cet objet alors : Kpimscgos. C'est quoi au juste? Son scope?

**wiss20000** · 19/04/2007, 11h39

Kpimscgos est de type Collection
voici une partie du code de ma servlet

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

//	 affichage liste 
	    private void doListPersonnes(HttpServletRequest request,
	    HttpServletResponse response) throws ServletException, IOException {
	    	request.setAttribute("Kpimscgos", service.getAll());
	    	 // affichage de la vue [list]
	    	 getServletContext()
	    	 .getRequestDispatcher((String) params.get("urlList")).forward(request, response);
	   }

avec service.getAll() me retourne une Collection

private ArrayList Kpim = new ArrayList();
...........................

**the_ugly** · 19/04/2007, 11h48

Essaie dans ton attribut items de mettre:

${request['Kpimscgos']}

Si ça marche toujours pas, j'espère que quelqu'un d'autre pourra t'aider lol

**wiss20000** · 19/04/2007, 12h10

merci pour ton effort

mais malheureusement ça ne marche pas

**wiss20000** · 19/04/2007, 13h26

tu peux s'il te plait préciser exactement la où je dois modifier (je crois que j'ai fait une erreur

)

A la place de false, tu mets true.

**wiss20000** · 19/04/2007, 13h50

le meme problème mais avec du changement du message d'erreur

org.apache.jasper.JasperException: /WEB-INF/vues/list.jsp(26,5) D'après la TLD, l'attribut value n'accepte aucune expression

au lieu de (24,1)

**the_ugly** · 19/04/2007, 14h19

Ca dit surtout "value" au lieu de "item". Fait la même manip pour tous les params que tu utilises.

**wiss20000** · 19/04/2007, 14h32

désolé mais j'ai pas compris
il n'existe pas de value dans c.tld

**the_ugly** · 19/04/2007, 14h35

C'est le value du c:out.

Tu le fais exprès ou quoi?
