Set page permissions to role programmatically

-
In JSP,

 // getting list of all public pages

 List<Layout> pageList = LayoutLocalServiceUtil.getLayouts(themeDisplay.getScopeGroupId(), false);

for(Layout pages : pageList){
<input type="checkbox" name='<portlet:namespace/>page' value="<%=pages.getPlid() %>" <%=checked%> /><%=pages.getName() %><%=pages.getPlid()  %>
}

In Controller,

 String[] pages = ParamUtil.getParameterValues(request, "page");

   for(String page : pages){
 long plId = Long.parseLong(page);
Layout layout = null;
try {
layout = LayoutLocalServiceUtil.getLayout(plId);

} catch (SystemException e) {


}

    ResourcePermissionServiceUtil.setIndividualResourcePermissions(themeDisplay.getScopeGroupId(),
   themeDisplay.getCompanyId(), Layout.class.getName(), String.valueOf(layout.getPrimaryKey()),

   role.getRoleId(), new String[] { ActionKeys.VIEW });
}
