Java Web Start problème pour l'écriture dans un fichier

**yoyolepsy** · 19/08/2009, 09h13

Bonjour,

Suite à la commande

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
 
this.getClass().forName("com.equipment.management_rule.ScheduleManagementRule")

que tu m'a proposé, Eclipse me dit que je ne peux pas accèder à la méthode forName(String) ed manière statique j'ai donc remplacé par :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3

this.getClass();	
 
Class.forName("com.equipment.management_rule.ScheduleManagementRule")

j'ai alors cette exception :

ok donc ton application principale vois bien la classe, mais pas le plugin :s. Pourrais-tu nous donner ta dernière version de loadPlugins() qu'on sache sur quoi on travaille après tous ces changement? Et met en évidence la ligne 93 au passage

En parlant de l'affichage tu me demandes, les messages consoles?

**tchize_** · 19/08/2009, 14h03

oui, il y a des system.out en plus et des lignes changées

**yoyolepsy** · 19/08/2009, 14h15

D'accord excuse moi je n'avais pas vu. Alors j'ai testé le code avec tes ajouts et j'obtiens le stacktrace suivant :

Bonjour,

Après plusieurs essais, je reste toujours bloqué avec mon problème de plugin jar. Quelqu'un aurait-il une idée ou une piste à me suggérer? D'avance. Merci

**tchize_** · 21/08/2009, 09h09

tu peux nous montrer le code de cette méthode

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

this.loadPluginInClassPath(url);

? Dans la logique du chargement d'un jar au sein d'un classloader, j'en vois pas l'intéret, et je me demande ce qu'elle tripatouille....

Edit: la seule raison que je verrais pour que la classe de ton plugin ne vois pas ta classe principale, ce serait que le plugin sois chargé par le classloader bootstrap et non par ton classloader (le principe de délégation donne priorité au classloader parent), et le bootstrap serait bien emmerdé parce que, ta classe principale il la connait pas. Peux tu ajouter ce code pour vérifier?

Code :

				if(tmpString.length() > 6 && tmpString.endsWith(".class")) {
				  //rajouté
		try {
			Enumeration<?> e = loader.getResources(tmpString);
			while (e.hasMoreElements())
				System.out.println(e.nextElement());
		} catch (IOException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
				  //fin rajout

ce code donnera exactement tous les emplacement ou l'on peux trouver la classe. Si t'as des doublons, ce sera bingo on aura trouvé la cause

Ok je rajoute le code. juste une question, dans la ligne :

Code :

Enumeration<?> e = TestUrls.class.getClassLoader().getResources(tmpString);

A quoi correspond :

Code :

TestUrls

? Pour que je puisse compiler

désolé, mauvaic copier/coller, j'ai corrigé mon post

**tchize_** · 21/08/2009, 09h47

ok, tu va me retirer cette méthode loadinclasspath immédiatement. Ton plugin n'a rien à faire dans le system classloader, il ne trouvrera aucune des classes de ton application à partir de là.

**yoyolepsy** · 21/08/2009, 09h59

En plus du code que tu m'a dit tu me demande de retirer l'appel à la méthode loadinclasspath dans loadplugins?

**yoyolepsy** · 21/08/2009, 10h16

J'ai retiré l'appel à ma fonction loadPluginInClassPath et la effectivement le plugin semble bien vu dans mon jws

. Je remarque aussi pour en revenir au début de la discussion que j'écris bien dans mon fichier de log . Par contre j'écris les informations deux fois ce que je ne comprends pas forcément.
Pourrais-tu m'expliquer exactement ce qui se passait avec la méthode loadPluginInClassPath qui apparemment me causait mes problèmes et pourquoi cele venait que en jws et pas en application lancé sous Eclipse??
En tous cas merci beaucoup pour ton aide et ta patience

**yoyolepsy** · 21/08/2009, 10h29

Envoyé par yoyolepsy

J'ai retiré l'appel à ma fonction loadPluginInClassPath et la effectivement le plugin semble bien vu dans mon jws

. Je remarque aussi pour en revenir au début de la discussion que j'écris bien dans mon fichier de log . Par contre j'écris les informations deux fois ce que je ne comprends pas forcément.
Pourrais-tu m'expliquer exactement ce qui se passait avec la méthode loadPluginInClassPath qui apparemment me causait mes problèmes et pourquoi cele venait que en jws et pas en application lancé sous Eclipse??
En tous cas merci beaucoup pour ton aide et ta patience

Les classloader vont toujours chercher en priorité dans leur parent les classes à charger , et il ne vont jamais chercher dans leur fils. Dans eclipse, le systemclassloader c'est l'ensemble de test classes de ton application que tu viens de lancer. Résultat, ca inclue dont ton pluginmanager. Résultat, le systemclassloader "vois" ton pluginmanager et toutes tes classes projet.

Dans javawebstart on a un niveau de plus. D'abord il y a le systemclassloader qui est celui de javawebstart, en dessous viens un classloader spécialement instancié pour ton application par webstart, avec ses sécurités, et qui contient tes classes, ensuite viennent tes petits classloader pour les plugins. Résultat, le systemclassloader ne "vois" aucune de tes classes. Quand tu injectais de force le plugin dans le system classloader, tu injectais donc tes classes plugins un niveau au dessus de ton application. Ceux-ci ne voient donc pas ton application principale. Et là tu te retrouve coincé car il ne vois aucune des classes dont il dépend -> NoClassDefFoundError.

En pratique, ton classloader custom est amplement suffisant pour charger les classes du plugin, pas besoin d'aller force des trucs.

PS: pour tes messages en double, regarde si ton splugin.jar n'est pas repris deux fois, par exemple une fois par ton classloader de plugin (qui est le comportement voulu) et une fois dans le fichier jnlp (ce qu'il faudrait, à priori, retirer)

**yoyolepsy** · 21/08/2009, 11h30

OK. Je comprends mieux mainteant les considérations sur les classloader. Je te remercie beaucoup du temps et de la patience que tu m'a apporté. Je vais maintenant essayer de continuer mon application avec mon JavaFX.

PS : En ce qui concerne les fichiers de log tu me dis de retirer la reference au plugin dans le jnlp?

**tchize_** · 21/08/2009, 11h45

si tu regarde le texte que tu ma copié / collé, tu verra qu'il trouve chaque classe deux fois. A chaque fois à partir du même jar, ce qui me laisse a penser que deux classloader dans la hierarchie possèdent le classe, ce qui est pas tiptop, tu risque a nouveau d'avoir des problème si tu fais évoluer ton système de plugin. CA viens probablement du fait que tu référence ton splugin.jar à la fois dans le jnlp et que en plus tu le charge manuellement dans un classloader fils -> retire le du jnlp, a priori t'en a pas besoin là.

**yoyolepsy** · 21/08/2009, 11h54

Si je retire la ligne suivante :
