Slt,

J'ai développé une Applet en Java (Dont la classe principale s'apelle "AgendaFrame.Java") qui fonctionne très bien depuis l'éditeur Eclipse,

J'ai essayé de l'appler depuis la JSP avec le code suivant :

=========================================================

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<applet code="AgendaFrame.class" 
 
codebase="http://localhost:8080/tandem/WEB-INF/lib/agenda"  archive="C:\Dev\Workspace\tandem\WEB-INF\lib\agenda.jar" 
 
width="100" height="95">
 
Votre browser ignore complètement le tag &lt;APPLET&gt; !
 
 
</applet>

=========================================================


Comme l'Applet était dans un projet à part, j'ai fait un (import) du code pour importer les fichier (.java) et (.class) dans mon projet Web [J'ai effectué l'import dans le répertoire "WEB-INF/lib/agenda" et un .jar (agenda.jar) dans "WEB-INF/lib/" de mon projet tomcat].

Une fois appelé depuis le navigateur avec le code mentionné ci dessus, le JSP concernée m'affiche un carré vide et en bas (Applet notinited)

Et la console Java affiche ceci:::

Java Plug-in 1.6.0_01
Utilisation de la version JRE 1.6.0_01 Java HotSpot(TM) Client VM
Répertoire d'accueil de l'utilisateur = C:\Documents and Settings\bekara_k

Merci d'avance pour votre aide !!!

Je ne pense pas que la JVM locale puis accéder aux sources si tu mets

codebase="http://localhost:8080/tandem/WEB-INF/lib/agenda

Il faut un répertoire accessible, or WEB-INF est protégé.
