have a applet (that I am trying to convert from a working java app to
an applet see code below)

the error I get is:

----------------------------------------------------
c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
m: print memory usage
q: hide console
s: dump system properties
t: dump thread list
x: clear classloader cache
0-5: set trace level to <n>

java.lang.ExceptionInInitializerError:
java.security.AccessControlException: access denied
(java.util.PropertyPermission * read,write)

    at adobeviewer.init(adobeviewer.java:100)
    at sun.applet.AppletPanel.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

Which I tried to fix in the init() using

if (theSession.isIE())
{
com.ms.security.PolicyEngine.assertPermission(com.ms.security.PermissionID.SYSTEM);
} else if (theSession.isNetscape())
{
netscape.security.PrivilegeManager.enablePrivilege("UniversalTopLevelWindow");
}

any idea how I can remedy this issue?
