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.

a blank Policy Tool window

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.
