Quick Tour of Controlling Applications

Set up the Policy File to Grant the Required Permissions

You will now use the Policy Tool to open the policy file named mypolicy created in the Quick Tour of Controlling Applets lesson. You will add a new policy entry that grants code from the directory where GetProps.class is stored permission to read the "user.home" and "java.home" property values.

The steps are the following:

1. Open the Policy File

2. Grant the Required Permissions

3. Save the Policy File

Note for Solaris users: The instructions illustrate creating the policy file for a Windows system. The steps are exactly the same if you are working on a Solaris system, but

• Where the text says to retrieve the mypolicy file from the C:\Test directory, you instead retrieve it from the test directory in your home directory.

• In the "Grant the Required Permissions" step, you can substitute file:${user.home}/test/ for file:/C:/Test/. Alternatively, you could directly specify your home directory, rather than referring to the "user.home" property, as in file:/home/susanj/test/.
