Olá Pessoal.

tenho a seguinte situação:

tenho uma JApplet que atravez de um parametro recebe uma string que representa um Array de bytes, e apartir desta String tenho que recriar o array de bytes e desserializar o Objeto, neste caso um ChartPanel.

O erro ocorre no momento de desserializar o ChartPanel:

Da o seguinte erro:

java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.swing)
	at java.security.AccessControlContext.checkPermission(Unknown Source)

Ah e detalhe, testando apartir do Eclipse ele funcionar certinho.

Grato a todos.

Toda vez que você recebe um erro desses, normalmente é o caso de assinar digitalmente sua applet.
