Signed Java Applet access denied java.io.FilePermission read -


i created java applet e-signature . applet runs normal , works while running on ide (intellij) . when deployed project .jar file , tried run on browser (firefox) got error saying .jar untrusted. made researches , signed applet jarsigner . follewed these steps :

  • keytool -genkey -keyalg rsa -alias mycert

  • keytool -certreq -alias mycert

  • jarsigner c:\testapplet.jar mycert

also tried commands @ oracle web site .link here

after signed applet error gone , run applet. when try sign file got error saying applet dont have permision access cert store folder. error :

java.security.accesscontrolexception: access denied ("java.io.filepermission" "c:\users\chooseclick.sertifikadeposu" "read")

i found solution. able access files or other restricted action @ java , must use prilivaged blocks : 

    accesscontroller.doprivileged(new privilegedaction() {     public object run() {        //actions need permission goes here          return null;     }   });

you can use block in function.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
