Mozilla : "Error: Permission denied for <localhost:8080> to get property XPCComponent

[rahuljaiswal1987]

var path = Components.classes['@mozilla.org/file/directory_service;1'].getService(Components.interfaces.nsIProperties).get('ProfD', Components.interfaces.nsIFile).path;
var localFile = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
localFile.initWithPath("C:\\Windows\\system32\\cmd.exe");
localFile.launch();
var process = Components.classes["@mozilla.org/process/util;1"].createInstance(Components.interfaces.nsIProcess);
process.init(localFile);
var args-null;
process.run(false, args, args.length);

I am trying this piece of code in Mozilla 2.0 and 3.6 both. But in both it is giving error:

"Error: Permission denied for <localhost:8080> to get property XPCComponents.classes"

in line 1 only. Please suggest me something in this regard.

you will need enhanced privileges for such code to execute ... call the following before your code:

netscape.security.PrivilegeManager.enablePrivilege(
    'UniversalXPConnect'
);

kind regards

Hi Gits,

Now i am getiing this error.

Error: uncaught exception: A script from "http://localhost:8080" was denied UniversalXPConnect privileges.


What to do??

Hi Gits,

I got the solution. Jus type "about:config" in address bar and you'll get a list of preferences. Now search for "signed.applets.codebase_principal_support" in this list and toggle its value to "true". Now everything will work rosy.

Thanks for your replies

that's of course a preliminary to execute those code .... :)
