7: Create the Policy File
The policy file grants the SSignedApplet.jar file signed by the alias
company permission to create demo.ini (and no other file) in the
user's home directory.
Ray creates the policy file in his home directory using either
policytool or an ASCII editor.
keystore "/home/ray/raystore";
// A sample policy file that lets a program
// create demo.ini in user's home directory
// Satya N Dodda
grant SignedBy "company" {
permission java.util.PropertyPermission
"user.home", "read";
permission java.io.FilePermission
"${user.home}/demo.ini", "write";
};
8: Run the Applet in Applet Viewer
Applet Viewer connects to the HTML documents and resources specified
in the call to appletviewer, and displays the applet in its own
window. To run the example, Ray copies the signed JAR file and HTML
file to /home/aURL/public_html and invokes Applet viewer from his home
directory as follows:
appletviewer -J-Djava.security.policy=Write.jp
http://aURL.com/SignedApplet.html
Note: Type everything on one line and put a space after Write.jp
The -J-Djava.security.policy=Write.jp option tells Applet Viewer to
run the applet referenced in the SignedApplet.html file with the
Write.jp policy file.
Note: The Policy file can be stored on a server and specified in the
appletviewer invocation as a URL.
Running an Application with a Policy File
This application invocation restricts MyProgram to a sandbox-like
environment the same way applets are restricted, but allows access as
specified in the polfile policy file.
java -Djava.security.manager
-Djava.security.policy=polfile MyProgram
