How to signout programmatically from Liferay custom portlet - liferay

I am creating a custom portlet.
And I need to log-out the User from the portal after he performs some operation in my custom portlet. I am extending liferay's MVCPortlet.
In one of MyPortlet's action methods I need to write the code to logout the user and then redirect it to the home page.
Update:
I tried the following which I think logs out the user but does not redirect to the home page after logging out:
actionResponse.sendRedirect(PortalUtil.getPortalURL(actionRequest) + "/c/portal/logout");
Thanks All

Well this may be a very late reply, but it may help somebody
Firstly, you have to validate the session and the re-direct to the logout URL. Otherwise, the session remains and the user is moved to the landing page, even though we redirect to the logout url. So, this is what one should do
HttpServletRequest request = PortalUtil.getHttpServletRequest(actionRequest);
request.getSession().invalidate();
actionResponse.sendRedirect(themeDisplay.getURLSignOut());
Hope this helps.

I also did not find a way to send a specific redirect by using liferay's default logout (/c/portal/logout). So I logged out the user programmatically with the util class AuthenticatedSessionManagerUtil and
afterwards sending a specific redirect location within the response object, e.g. response.sendRedirect(yourLocation)
Note:
With Liferay 7.2 I used AuthenticatedSessionManagerUtil.signOutSimultaneousLogins(userId) instead of AuthenticatedSessionManagerUtil.logout(userId) which did not work for me.

You can redirect to c/portal/logout
more precisely :
actionResponse.sendRedirect("/c/portal/logout/");

Just leaving this here after facing this problem (LR7):
try {
AuthenticatedSessionManagerUtil.logout(request, response);
request.setAttribute(WebKeys.LOGOUT, true);
}

All you have to do is
perform operation: at the end of operation use this:
HttpSession session = PortalUtil.getHttpServletRequest(request).getSession();
session.invalidate();
try {
System.out.println(" redirecting to the required page");
response.sendRedirect(themeDisplay.getPortalURL() + "/page-on-which-to-be-redirected");
} catch (IOException e1) {
e1.printStackTrace();
}

Modx manager custom page check if user is logged in and has manager access

I am developing modx manager custom page and cannot check if user is logged in and has access to manager ? So far I tried
$modx->user->get('username');
All i get is (anonymous) even if i am logged in and when i am not logged in.I have also tried sessioncontext etc as well. Am i doing something wrong. Did anyone faced same issue.
You need a custom snippet to manage showing things for people who are logged in or not and the Login Extra to easily access user fields. Then paste this in and call it isAdmin:
<?php
if ($modx->user instanceof modUser) {
if ($modx->user->hasSessionContext('mgr')) {
return true;
}
}
return false;
And then you want to use it like this...
[[!isAdmin:notempty=`
<!-- Do something for people logged in -->
`:default=`
<!-- Do something for everyone else -->
`]]
Code is from Mark Hamstra's blog.

How to write servlet filter to destroy all cookies related to domain on browser

I am new to servlet filter.
I am using JSF 2.2, Wildfly 8.1. I have figured out that if user clicks log out link when session is already expired then when user logs in again the system will continiously fire exception of session expired. BalusC wrote to write servlet filter which will delete all cookies of specific domain before user will see welcome page.
How to write servlet filter which will destroy all cookies related to specific domain (domain.com) when new session will start? I played with it and absolutely confused. sorry for my a little experience in jsf.
I think you need to set cookie.setMaxAge(0);for all the cookie for that domain.
Inside your filter(which should be used for Logout request only) or in Logout servlet(if any) you can write below line to delete all cookie.
Cookie[] cookies = req.getCookies();
if(cookies != null){
for(Cookie cookie : cookies){
cookie.setValue("");
cookie.setPath("/");
cookie.setMaxAge(0);
resp.addCookie(cookie)
}
}

Logged in user can only access 1 page?

Using Orchard 1.6 Iv created a new role 'FactoryWorker'. When this user logs in from the front end I want them to be navigated to one page only.
OrchardLocal/System/ManufacturedProducts
I have set this page to be a print screen of the order details so the factory worker will know what products to get ready for ship out & they wont be able to navigate as no menu appears, but also need the other pages blocked incase the user decides to enter the URL of a page they arnt allowed access to.
This is the only page I want this particular user to be able to access(after they login), and I have added a logout button, which logs out the user and returns them to the home page.
So iv been looking through editing a role, with permissions and content etc...but this all seems to be applying to forms and content in general. where the user can access any content type etc...
So can someone advise me on how to do this?
thanks for any replies
UPDATE
I forgot to mention that this is not a content type, item or part I am talking about.
I have created my own controller & View & VM which is accessible from the dash board (using the AdminMenu, which brings the admin user to OrchardLocal/System/ManufacturedProducts)
I have looked at Orchard.ContentPermissions Feature but it only seems to allow me to 1)Grant permissions for others or 2)Grant permission for own content
any ideas?
You can use a Request Filter, (I do not know if it is the best way) :
FilterProvider – defines the filter applied to each request. Resembles the way default ASP.NET MVC action filters work with the difference that it’s not an attribute. All FilterProvider objects are injected into the request pipeline and are applied to all requests (so you need to check if the current request is suitable for your filter at the beginning of an appropriate method).
From : http://www.szmyd.com.pl/blog/most-useful-orchard-extension-points
So you could implement something like this
public class Filter : FilterProvider, IAuthorizationFilter {
private readonly IAuthenticationService _authenticationService;
public Filter(IAuthenticationService authenticationService) {
_authenticationService = authenticationService;
}
public void OnAuthorization(AuthorizationContext filterContext) {
//If route is the restricted one
if (filterContext.HttpContext.Request.Url.AbsoluteUri.Contains("OrchardLocal/System/ManufacturedProducts")) {
//Get the logged user
IUser loggedUser = _authenticationService.GetAuthenticatedUser();
if (loggedUser == null)
return filterContext.Result = new HttpUnauthorizedResult();
//Get the Roles
var roles = loggedUser.As<IUserRoles>().Roles;
if (!roles.Contains("FactoryUser")) {
//User is not authorized
return filterContext.Result = new HttpUnauthorizedResult();
}
}
}
}
Note: Untested code!
EDIT: Also you could invert the logic and check if the logged user has the role 'FactoryUser' and restrict its access to every page except the one they should see.
Your module can create a new permission (look at one of the permissions.cs files for examples), then create a role that has only that permission. Have your controller action check that permission (again, many examples found by finding usage of the permissions defined in one of the permissions.cs).
You can use the Content Permissions module. Using this module you can attach a content item permission part to a content type. This part allows you to choose which roles can see the content when you create it.

JSF to Bean to JSF

So I'm having a problem trying to pass a String value.
The String value is entered through a login page as username.
The JSF then calls the Bean to verify log in information then proceeds to another JSF page.
I was wondering how to pass the username along to the new JSF page. Thank you.
If you're performing a navigation instead of a redirect, then you basically don't need to do anything. The information is also just available in the navigated page.
E.g. in login page,
<h:inputText value="#{bean.username}" />
and in the navigated page:
<p>You have entered the following username: #{bean.username}</p>
If you're however performing a redirect instead of a navigation, then you basically need to store the information in a bit broader scope. You didn't clearly elaborate the concrete functional requirement in the question, but if I guess it right, you just wanted to remember the currently logged-in user for the remaining of the HTTP session. In that case, just store it in the session scope during the login action.
public String login() {
// ...
User user = userService.find(username, password);
// ...
externalContext.getSessionMap().put("user", user);
// ...
return "nextpage?faces-redirect=true";
}
This way it's available by #{user} throughout the entire HTTP session.
<p>You're logged in as #{user.name}.</p>
You can also use <t:saveState> without using session scope. <t:saveState> is longer than the request scope but shorter than session scope.
This may help you : http://myfaces.apache.org/tomahawk-project/tomahawk12/tagdoc/t_saveState.html

What to do to restrict the user from seeing the page with out login the website?

I want a page has to appear to user after logged in. But if we use that link we can see the page and its content only thing is that it wont be having user data. what to do to prevent this. what can be done in this scenario ?
You can declare a PhaseListener where to redirect to the homepage instead the user is not logged
public void afterPhase(PhaseEvent evt) {
User user =
evt.getFacesContext().getExternalContext().getSessionMap().get(USER_KEY);
if (user == null) {
FacesContext.getExternalContext().redirect("home.xhtml");
}
}
The phase listener can be defined globally, or at view-level with:
<f:view afterPhase="#{bean.afterPhase}">...</f:view>
(in facelets the attribute is called afterPhaseListener)
Use a ServletFilter to check existence of UserData in Session.
If "yes: then forward else forward to error page.
Another option is to use the rendered attribute on tags to check the existence of UserData object.
I'm not familiar with JSF or if it has built in authentication/authorization. But you should be able to apply authentication/access rules directly on your web server.
