[news.eclipse.newcomer] can't launch an applet that belongs to a package

[triglian@xxxxxxxxx (Vasileios triglianos)]

hey...
Im working on a package of Swing classes which among other contains a 
swing applet.
I want to launch the applet using iexplorer. the classes of the 
package(the package was created automatically by eclipse using the 
available option)are inside a file called 
"testpack"("../workspace/testing/testpack"). 
An "test.html" file that i use to launch the applet is just in the upper 
directory ("../workspace/testing").

i write code="testpack.CreateNodeSAIDemo.class" in the html code of 
"test.html"
to access the applet class.

When i run it in ie i get the following exception:
java.security.AccessControlException: access denied 
(java.lang.RuntimePermission exitVM)
	at java.security.AccessControlContext.checkPermission(Unknown Source)
	at java.security.AccessController.checkPermission(Unknown Source)

I don't know what to do to make it work.

I've tried:
grant codeBase "file:C:\RU6/workspace/testing/testpack/*"{
		permission java.security.AllPermission;
	};
	grant codeBase "file:C:\RU6\workspace\testing\*"{
		permission java.security.AllPermission;
	};

but still it doesn't work
Any help would be very much appreciated
