applet-servlet communication

[malvika Pandit]

Hi Everyone
I am writing a client-server program using Java applet-servlet repectively
I use URLConnection con = urlServlet.openConnection(); for the connection

My program works well on local host, however when I try on LAN ie on remote host it gives java.security.AccessControl Exception Socket Permission denied to 192.168.2.55(remote host) (connect, resolve)

I have changed the java.policy file socketpermission to listen,accept,connect,resolve
But this problem is still there.
What is the solution to this?
Please help.
Thanks
Malvika
