Package org.picocontainer.security

Class CustomPermissionsURLClassLoader

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public class CustomPermissionsURLClassLoader
extends java.net.URLClassLoader
    CustomPermissionsURLClassLoader extends URLClassLoader, adding the abilty to programatically add permissions easily. To be effective for permission management, it should be run in conjunction with a policy that restricts some of the classloaders, but not all. It's not ordinarily used by PicoContainer, but is here because PicoContainer is common to most classloader trees.
