Java从代码授予许可

Question

I am currently setting a policy file using:

policyURL =cl.getResource("res/policy/abc.policy");
System.out.println(policyURL.toString());
System.setProperty("java.security.policy", policyURL.toString());

The problem is that the file interferes with other running applications.

Is it possible to grant a permission from code and remove it when the application stops? I don't want to modify the java.policy from ProgramFiles.

Answer 1

Can't you set it on the JVM through the following properties:

java -Djava.security.manager -Djava.security.policy=res/policy/abc.policy

I would suspect this would not impact other running applications.
