ADD PortletResource permission for specific users to VIEW custom portlet PROGRAMATICALLY - permissions

Question

I want my custom portlet to be view-able by specific users but they're ALL MEMBERS OF SAME GROUP/SITE.
i.e...
User 1: my custom Portlet is not view-able
Admin: my custom portlet is view-able
User 2: my custom portlet is view-able
How to ADD Portlet-Resource permission for particular user to VIEW custom portlet PROGRAMATICALLY in my Jsp???
Here's my code..
<%#page import="com.liferay.portal.security.permission.ActionKeys"%>
<%#page import="com.liferay.portal.security.permission.PermissionChecker"%>
<%#page import="com.liferay.portal.model.Permission"%>
<%# taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%>
<%# page import="com.liferay.portal.theme.ThemeDisplay" %>
<%# page import="com.liferay.portal.kernel.util.WebKeys" %>
<%# taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %>
<%#page import="com.liferay.portal.service.RoleLocalServiceUtil"%>
<%#page import="com.liferay.portal.service.UserLocalServiceUtil"%>
<portlet:defineObjects />
<theme:defineObjects/>
<% ThemeDisplay themeDisplay = ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
PermissionChecker permissionChecker = themeDisplay.getPermissionChecker();
long companyId = themeDisplay.getCompanyId();
long roleId = RoleLocalServiceUtil.getRole(companyId, "Administrator").getRoleId();
long userId = themeDisplay.getUserId();
UserLocalServiceUtil.hasRoleUser(roleId, userId);
if(permissionChecker.hasPermission(roleId, "com.test.sokbu", 10162, ActionKeys.VIEW)){System.out.println("Ok!");}%>
Thank you in advance!
Best Regards,

Answer 1

I just followed this link http://agile-reflections.opnworks.com/2011/07/experimenting-with-liferay-permissions.html and viola! it's now working! =) Thanks to Sir Laurent Gauthier
THIS IS MY SAMPLE.
STEP 1
Create a resource-actions folder inside docroot/WEB-INF/src
Create perm.xml
<?xml version='1.0' encoding='UTF-8'?>
<resource-action-mapping>
<portlet-resource>
<portlet-name>permissions</portlet-name>
<permissions>
<supports>
<action-key>VIEW</action-key>
<!-- <action-key>DELETE</action-key> -->
</supports>
<site-member-defaults>
<!-- <action-key>VIEW</action-key> -->
<!-- <action-key>DELETE</action-key> -->
</site-member-defaults>
<guest-defaults>
<!-- <action-key>VIEW</action-key> -->
</guest-defaults>
<guest-unsupported>
<action-key>VIEW</action-key>
</guest-unsupported>
</permissions>
</portlet-resource>
</resource-action-mapping>
Create default.xml
<?xml version="1.0"?>
<resource-action-mapping>
<resource file="resource-actions/perm.xml" />
</resource-action-mapping>
STEP 2
- Create a file named portlet.properties inside docroot/WEB-INF/src
- Insert this.. resource.actions.configs=resource-actions/default.xml
STEP 3
- Insert <add-default-resource>true</add-default-resource> after </css-class-wrapper> tag in liferay-portlet.xml.
STEP 4
Here I followed what's on the blog of Sir Laurent..
Open a browser on your Liferay instance as Liferay administrator
Create a new role named "Example Role"
Create a new user named "Example User" and set the user's password
Assign the "Example Role" to the newly created user
Open a different browser on your Liferay instance so as to have a different session, log in as "Example User" and navigate to the page containing this portlet
Pls Note
Whenever I have changes in perm.xml, I restart my server for changes to take effect.
