how to display a JFrame from an applet?
- by mithun1538
Hello everyone,
I have this class called PollFrame that extends JFrame in a file called PollFrame.java . PollFrame contains a form. I have an applet, which has a button in it. When the button is clicked, I want the PollFrame to be displayed. I set the ActionPerformed as:
Pollframe poll = new PollFrame(); // This initializes the form
poll.setVisible(true);
However, when I click the button, I get the following error :
Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.lang.RuntimePermission exitVM.0)

I am guessing fromt he above error that calling another class file from an applet is prohibited. Is there any way I can display the PollFrame from the applet?
