VM security problem?
Good day, I've got a problem (but really it's an error) with SWING Applets.
I must say that I'm absolutely new to the Applet programming but, after spending some hours working about the integration of an applet in an HTML page, I have just one exception, that is to say:
java.security.AccessControlException: access denied (java.lang.RuntimePermission exitVM)

This ugly mess jumped off when I tried to create a new JFrame, that I've put in the package "shop.main.JAppMain". Here the piece of code that I used to do this, located in a "MouseClicked" event:
try {
new shop.main.JMainApp().setVisible(true);
return;
} catch(Exception e){ e.printStackTrace(); return; }
Hope for someone who can help me, I send you my best regards.

P.s.: My personal English vocabulary is very poor, so excuse me if I can't explain better the problem...
