Start Policy Tool

> To start Policy Tool, simply type the following at the command line:

> >     policytool

> This brings up the Policy Tool window.

> Whenever Policy Tool is started, it attempts to fill in this window with policy information from the user policy file. The user policy file is named `.java.policy` by default in your home directory. If Policy Tool cannot find the user policy file, it issues a warning and displays a blank Policy Tool window (a window with headings and buttons but no data in it), as shown in the following figure.

> This figure has been reduced to fit on the page.
> Click the image to view it at its natural size.

> You can then proceed to either open an existing policy file or to create a new policy file.

> The first time you run the Policy Tool, you will see the blank Policy Tool window, since a user policy file does not yet exist. You can immediately proceed to create a new policy file, as described in the next step.
