Bonjour à tous,

1)

Je me remets au java depuis peu, j'ai tout d'abord installé un JRE (jre-6u14), un JDK (jdk-6u14) ainsi que Netbeans-6.7 lorsque je veux tester ma JVM sur le site de sun :

http://java.com/en/download/help/testvm.xml

ca ne marche pas voici mon exception :
---------------------------------------

Java Plug-in 1.6.0_14

c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
m: print memory usage
o: trigger logging
q: hide console
r: reload policy configuration
s: dump system and deployment properties
t: dump thread list
v: dump thread stack
x: clear classloader cache
0-5: set trace level to <n>
----------------------------------------------------

2) Si j'essaye à partir de NetBeans où dans une page web (JSP), je fais appel à une applet des plus basique :

<applet code="JAppletHello.class" CODEBASE="file://C:/Documents and Settings/lema/NetBeansProjects/loloPortal/build/web/WEB-INF/classes/" width="150" height="25">
</applet>

Ca me fait le meme résultat : Class not found...

Je me demande si ces deux erreurs ne résultent pas d'un problème de classpath. Qu'en pensez vous?

D'ores et déjà merci pour vos réponses.

Personne n'a de réponse?

Ma console java ne me retourne pas d'erreur...

Cher Alex,

Pour le point 1. Deja un truc que je trouve curieux c'est que parfois l'applet de test sun marche, mais parfois elle crash ici sur ma machine.

Dont voici le stacktrace :

	at java.lang.Thread.run(Unknown Source)

Ce qui entre nous est fort bizarre...

[l3malex]

Peut-être un problème du policy file?

Je n'y ai pas touché...
