Chapter 10.

Kernel Tutorial

This chapter discusses how to use permissioning and domain objects, answers frequently-asked ques-

tions about the WAF security mechanisms and API, and touches on extending the authentication

system. Please refer to Chapter 3 WAF Component: Kernel for more information about the concepts

used in these tutorials.

10.1. Permissions Tutorial

10.1.1. Granting Access

Granting access to a party is accomplished by creating a PermissionDescriptor and passing it to

PermissionService.grantPermission. The following example grants read privilege on MyAC-

SObject 50 to Group 5:

import com.arsdigita.kernel.permissions.PermissionService;

import com.arsdigita.kernel.permissions.PermissionDescriptor;

import com.arsdigita.kernel.permissions.PrivilegeDescriptor;

import com.arsdigita.persistence.OID;

OID acsObject = new OID("example.MyACSObject",

new BigDecimal(50));

OID party = new OID("com.arsdigita.kernel.Group", new BigDecimal(5));

PermissionDescriptor perm =

new PermissionDescriptor(PrivilegeDescriptor.READ,

acsObject, party);

PermissionService.grantPermission(perm);

The next example grants admin privilege on all objects to User 100:

import com.arsdigita.kernel.permissions.PermissionService;

import com.arsdigita.kernel.permissions.UniversalPermissionDescriptor;

import com.arsdigita.kernel.permissions.PrivilegeDescriptor;

import com.arsdigita.persistence.OID;

OID party = new OID("com.arsdigita.kernel.User", new BigDecimal(100));

PermissionDescriptor perm =

new UniversalPermissionDescriptor(PrivilegeDescriptor.ADMIN,

party);

PermissionService.grantPermission(perm);
