Concepts and Types - TypesPermissionsPermissionsPermissions represents a set of security permissions granted or revoked toa specific part code executed in the JVM where Apache Ant is running in.The actual Permissions are specified via a set of nested permission items either<grant>ed or <revoke>d. In the base situation a base set of permissions granted. Extra permissions can begranted. A granted permission can be overruled by revoking a permission.The security manager installed by the permissions will throw an SecurityException ifthe code subject to these permissions try to use an permission that has not been granted or that has been revoked. Nested elementsgrantIndicates a specific permission is always granted. Its attributes indicate which permissions are granted. | Attribute | Description | Required | | class | The fully qualified name of the Permission class. | Yes | | name | The name of the Permission. The actual contents depends on the Permission class. | No | | actions | The actions allowed. The actual contents depend on the Permission class and name. | No | Implied permissions are granted. Please note that some Permission classes may actually need a name and / or actions in order to function properly. The name and actions are parsed by the actualPermission class. revokeIndicates a specific permission is revoked. | Attribute | Description | Required | | class | The fully qualified name of the Permission class. | Yes | | name | The name of the Permission. The actual contents depends on the Permission class. | No | | actions | The actions allowed. The actual contents depend on the Permission class and name. | No | Implied permissions are not resolved and therefore also not revoked. The name can handle the * wildcard at the end of the name, in which case all permissions of the specified class of which the name starts with the specified name(excluding the *) are revoked. Note that the - wildcard often supported by thegranted properties is not supported.If the name is left empty all names match, and are revoked.If the actions are left empty all actions match, and are revoked. Base setA permissions set implictly contains the following permissions:<grant class="java.net.SocketPermission" name="localhost:1024-" actions="listen"><grant class="java.util.PropertyPermission" name="java.version" actions="read"><grant class="java.util.PropertyPermission" name="java.vendor" actions="read"><grant class="java.util.PropertyPermission" name="java.vendor.url" actions="read"><grant class="java.util.PropertyPermission" name="java.class.version" actions="read"><grant class="java.util.PropertyPermission" name="os.name" actions="read"><grant class="java.util.PropertyPermission" name="os.version" actions="read"><grant class="java.util.PropertyPermission" name="os.arch" actions="read"><grant class="java.util.PropertyPermission" name="file.encoding" actions="read"><grant class="java.util.PropertyPermission" name="file.separator" actions="read"><grant class="java.util.PropertyPermission" name="path.separator" actions="read"><grant class="java.util.PropertyPermission" name="line.separator" actions="read"><grant class="java.util.PropertyPermission" name="java.specification.version" actions="read"><grant class="java.util.PropertyPermission" name="java.specification.vendor" actions="read"><grant class="java.util.PropertyPermission" name="java.specification.name" actions="read"><grant class="java.util.PropertyPermission" name="java.vm.specification.version" actions="read"><grant class="java.util.PropertyPermission" name="java.vm.specification.vendor" actions="read"><grant class="java.util.PropertyPermission" name="java.vm.specification.name" actions="read"><grant class="java.util.PropertyPermission" name="java.vm.version" actions="read"><grant class="java.util.PropertyPermission" name="java.vm.vendor" actions="read"><grant class="java.util.PropertyPermission" name="java.vm.name" actions="read">
These permissions can be revoked via <revoke> elements if necessary.Examples<permissions> <grant class="java.security.AllPermission"/> <revoke class="java.util.PropertyPermission"/></permissions>
Grants all permissions to the code except for those handling Properties. <permissions> <grant class="java.net.SocketPermission" name="foo.bar.com" action="connect"/> <grant class="java.util.PropertyPermission" name="user.home" action="read,write"/></permissions>
Grants the base set of permissions with the addition of a SocketPermission to connectto foo.bar.com and the permission to read and write the user.home system property.
