Configure the jGuard.policy file

Configure the jGuard.policy file

Edit the jGuard.policy file (located under the ${java.home}/lib/security/ directory) with your specific settings:
'defaultPolicy' is the name of your default Policy furnished by the JVM vendor. For example:

defaultPolicy=sun.security.provider.PolicyFile

After these 5 steps, your jvm is configured to use jGuard, and you have set the authorization mechanism for each webapp.
