Class SharedActivationPolicyPermission

java.lang.Object

java.security.Permission

org.apache.river.start.SharedActivationPolicyPermission

All Implemented Interfaces:

Serializable, Guard

public final class SharedActivationPolicyPermission
extends Permission
implements Serializable

Permission class used by the service starter package. This class takes a policy string argument that follows the matching semantics defined by FilePermission. The ActivateWrapper class explicitly checks to see if the service's import codebase has been granted access to service's associated policy file in the shared VM's policy.

An example grant is:

 grant codebase "file:install_dir/lib/fiddler.jar" {
     permission org.apache.river.start.SharedActivationPolicyPermission 
         "policy_dir${/}policy.fiddler";
 };
 

This grant allows services using install_dir/lib/fiddler.jar for their import codebase to use policy_dir${/}policy.fiddler for their policy file, where install_dir is the installation directory of the Apache River release and policy_dir is the pathname to the directory containing the policy file.
