Cela peut arriver si la classe indiquée dans la propriété Implementation Class de l'item n'existe pas dans le fichier .jar

J'ai modifié le classpath et maintenant j'ai ceci comme problème.

Pourquoi n'ai je pas les droits de lire alors que j'ai signé le jar ?

Jamis vu ce message

Netscape security model is no longer supported.
Please migrate to the Java 2 security model instead.

vous utilisez quel navigateur ?

**patmaba** · 31/03/2006, 09h30

Internet explorer 6.

J'ai résolu le problème sur ma machine local.

Par contre lors du déploiement, je sais pas comment je vais faire.

Le problème est que mon composant désire faire des accès disque. Et le Jinit l'interdit, donc le comoposant déconne.

Pour donner les droit d'acces sur disque, j'ai modifier le fichier de configuration de jinit : <JINIT_PATH>\lib\security\java.policy

ajouter une ligne avec l'acces de votre certivicat

Code :

grant signedBy "Le NOM DE VOTRE CERTIFICAT" {
	permission java.security.AllPermission;
};

Le problème d'acces io sera résolut.

Cependant, je recontre en runtime un comportement bizarre de mon composant java. Il est légerement décaler et ne suit pas convenablement le layout de forms. bizarre.
