Trail: Security in JDK 1.2
Lesson: 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 granting permission for code from the directory where `GetProps.class` is stored to read the `"user.home"` and the `"java.home"` property values, as shown in the following figure.

> The steps are as follows.

> 1. Open the Policy File

> 2. Grant the Required Permissions

> 3. Save the Policy File

> > Note for UNIX Users: The instructions illustrate creating the policy file for a Windows system. The steps are exactly the same if you are working on a UNIX system, with the following differences.
> > - You retrieve the `mypolicy` file from the `test` directory in your home directory.

> > - For the CodeBase URL in the step for granting the required permissions, 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/`.
