Signing Code and Granting It Permissions
Set Up a Policy File to Grant the Required Permission
Next, you will use the Policy Tool to
create a policy file named raypolicy
and in it grant a permission to code from
a signed JAR file.
The JAR file must have been signed using the
private key corresponding to the public key imported into Ray's
keystore (raystore) in the previous step.
The certificate containing the public key is aliased by susan in
the keystore. We will grant such code permission to read any file in the
C:\TestData\ directory.
The steps are:
- Start Policy Tool
- Specify the Keystore
- Add a Policy Entry with a SignedBy Alias
- Save the Policy File
