Applet and Servlet Communication : java.security.AccessControlException:

[Anbarasu Selvaraj]

Applet is trying to communicate servlet. (It is communicating), after some process in servlet i am passing control to jsp (via response.sendRedirect). but i am receiving the error like bellow

java.security.AccessControlException: access denied (java.util.PropertyPermission http.strictPostRedirect read)

Please advise.

Using a client-side redirect does not make sense during applet/servlet communication. Either do a forward on the server side, or -if you want to replace the page that shows the applet in the browser- use AppletContext.showDocument in the applet.
