Programatically setting security Policy

843811

I'm trying to reduce the number of arguments that have to pass to my program. I have a configuration file that I would like to specify java.* properties in, and have my program set them as needed.

How do I set the Policy file for the VM without specifying java.security.policy on the command line. I tried:

System.setProperty("java.security.policy", "my policy file" )

When is that system property read?

I guess by default if u dont specify any Polciy file u get the default Policy with default Permissions automatically..
If u need to specify yr own policy then i guess u need to specify yr policy file...

here's what you have to do:
extend the class:
(in jdk 1.2) java.security.auth.Policy
(in jdk 1.3/1.4) java.security.Policy

and set up the policy in that code with permissions (and also override the getPermissions, etc methods (except for the setPolicy().

Then in your file java.security set the property "policy.provider" to your myPolicy class.

Then you'll have to make sure you give your code permissions to do what it needs to do.
