This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
I have an Applet which tries to open a file in the client machine. For this to work the jar file (in which the Applet class reside) is signed using the keytool and jarsigner. I have also created a policy file for enabling access to the Applet. The policy reads as below:
I need to allow the client to connect to hosts rather than the one it downloaded the applet from. Also I need the applet to have right to have read and write permission.
How should I set the permission file to allow it do so?
Thanks very much.

@Lin Shen: You would need a java.io.FilePermission and a java.net.SocketPermission. They can be combined in one grant statement, which, as in my earlier post, should also specify the URL the applet comes from. Reading the javadocs for those two classes will give you a start in what to do. The Applet FAQ, which is linked in my signature, has further links on using policy files with applets.
