I have written simple application with container-managed security. The problem is when I log in and open another page on which I logout, then I come back to first page and I click on any link etc or refresh page I get this exception. I guess it's normal (or maybe not:)) because I logged out and session is destroyed. What should I do to redirect user to for example index.xhtml or login.xhtml and save him from seeing that error page/message?
In other words how can I automatically redirect other pages to index/login page after I log out?
Here it is:
javax.faces.application.ViewExpiredException: viewId:/index.xhtml - View /index.xhtml could not be restored.

Introduction
The ViewExpiredException will be thrown whenever the javax.faces.STATE_SAVING_METHOD is set to server (default) and the enduser sends a HTTP POST request on a view via <h:form> with <h:commandLink>, <h:commandButton> or <f:ajax>, while the associated view state isn't available in the session anymore.
The view state is identified as value of a hidden input field javax.faces.ViewState of the <h:form>. With the state saving method set to server, this contains only the view state ID which references a serialized view state in the session. So, when the session is expired or absent for one of the following reasons ...
session object is timed out in server
session cookie is timed out in client
session cookie is deleted in client
HttpSession#invalidate() is called in server
SameSite=None is missing on session cookie (and thus e.g. Chrome won't send them along when a 3rd party site (e.g. payment) navigates back to your site via a callback URL)
... then the serialized view state is not available anymore in the session and the enduser will get this exception. To understand the working of the session, see also How do servlets work? Instantiation, sessions, shared variables and multithreading.
There is also a limit on the amount of views JSF will store in the session. When the limit is hit, then the least recently used view will be expired. See also com.sun.faces.numberOfViewsInSession vs com.sun.faces.numberOfLogicalViews.
With the state saving method set to client, the javax.faces.ViewState hidden input field contains instead the whole serialized view state, so the enduser won't get a ViewExpiredException when the session expires. It can however still happen on a cluster environment ("ERROR: MAC did not verify" is symptomatic) and/or when there's a implementation-specific timeout on the client side state configured and/or when server re-generates the AES key during restart, see also Getting ViewExpiredException in clustered environment while state saving method is set to client and user session is valid how to solve it.
Regardless of the solution, make sure you do not use enableRestoreView11Compatibility. it does not at all restore the original view state. It basically recreates the view and all associated view scoped beans from scratch and hereby thus losing all of original data (state). As the application will behave in a confusing way ("Hey, where are my input values..??"), this is very bad for user experience. Better use stateless views or <o:enableRestorableView> instead so you can manage it on a specific view only instead of on all views.
As to the why JSF needs to save view state, head to this answer: Why JSF saves the state of UI components on server?
Avoiding ViewExpiredException on page navigation
In order to avoid ViewExpiredException when e.g. navigating back after logout when the state saving is set to server, only redirecting the POST request after logout is not sufficient. You also need to instruct the browser to not cache the dynamic JSF pages, otherwise the browser may show them from the cache instead of requesting a fresh one from the server when you send a GET request on it (e.g. by back button).
The javax.faces.ViewState hidden field of the cached page may contain a view state ID value which is not valid anymore in the current session. If you're (ab)using POST (command links/buttons) instead of GET (regular links/buttons) for page-to-page navigation, and click such a command link/button on the cached page, then this will in turn fail with a ViewExpiredException.
To fire a redirect after logout in JSF 2.0, either add <redirect /> to the <navigation-case> in question (if any), or add ?faces-redirect=true to the outcome value.
<h:commandButton value="Logout" action="logout?faces-redirect=true" />
or
public String logout() {
// ...
return "index?faces-redirect=true";
}
To instruct the browser to not cache the dynamic JSF pages, create a Filter which is mapped on the servlet name of the FacesServlet and adds the needed response headers to disable the browser cache. E.g.
#WebFilter(servletNames={"Faces Servlet"}) // Must match <servlet-name> of your FacesServlet.
public class NoCacheFilter implements Filter {
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
if (!req.getRequestURI().startsWith(req.getContextPath() + ResourceHandler.RESOURCE_IDENTIFIER)) { // Skip JSF resources (CSS/JS/Images/etc)
res.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
res.setHeader("Pragma", "no-cache"); // HTTP 1.0.
res.setDateHeader("Expires", 0); // Proxies.
}
chain.doFilter(request, response);
}
// ...
}
Avoiding ViewExpiredException on page refresh
In order to avoid ViewExpiredException when refreshing the current page when the state saving is set to server, you not only need to make sure you are performing page-to-page navigation exclusively by GET (regular links/buttons), but you also need to make sure that you are exclusively using ajax to submit the forms. If you're submitting the form synchronously (non-ajax) anyway, then you'd best either make the view stateless (see later section), or to send a redirect after POST (see previous section).
Having a ViewExpiredException on page refresh is in default configuration a very rare case. It can only happen when the limit on the amount of views JSF will store in the session is hit. So, it will only happen when you've manually set that limit way too low, or that you're continuously creating new views in the "background" (e.g. by a badly implemented ajax poll in the same page or by a badly implemented 404 error page on broken images of the same page). See also com.sun.faces.numberOfViewsInSession vs com.sun.faces.numberOfLogicalViews for detail on that limit. Another cause is having duplicate JSF libraries in runtime classpath conflicting each other. The correct procedure to install JSF is outlined in our JSF wiki page.
Handling ViewExpiredException
When you want to handle an unavoidable ViewExpiredException after a POST action on an arbitrary page which was already opened in some browser tab/window while you're logged out in another tab/window, then you'd like to specify an error-page for that in web.xml which goes to a "Your session is timed out" page. E.g.
<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>/WEB-INF/errorpages/expired.xhtml</location>
</error-page>
Use if necessary a meta refresh header in the error page in case you intend to actually redirect further to home or login page.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Session expired</title>
<meta http-equiv="refresh" content="0;url=#{request.contextPath}/login.xhtml" />
</head>
<body>
<h1>Session expired</h1>
<h3>You will be redirected to login page</h3>
<p>Click here if redirect didn't work or when you're impatient.</p>
</body>
</html>
(the 0 in content represents the amount of seconds before redirect, 0 thus means "redirect immediately", you can use e.g. 3 to let the browser wait 3 seconds with the redirect)
Note that handling exceptions during ajax requests requires a special ExceptionHandler. See also Session timeout and ViewExpiredException handling on JSF/PrimeFaces ajax request. You can find a live example at OmniFaces FullAjaxExceptionHandler showcase page (this also covers non-ajax requests).
Also note that your "general" error page should be mapped on <error-code> of 500 instead of an <exception-type> of e.g. java.lang.Exception or java.lang.Throwable, otherwise all exceptions wrapped in ServletException such as ViewExpiredException would still end up in the general error page. See also ViewExpiredException shown in java.lang.Throwable error-page in web.xml.
<error-page>
<error-code>500</error-code>
<location>/WEB-INF/errorpages/general.xhtml</location>
</error-page>
Stateless views
A completely different alternative is to run JSF views in stateless mode. This way nothing of JSF state will be saved and the views will never expire, but just be rebuilt from scratch on every request. You can turn on stateless views by setting the transient attribute of <f:view> to true:
<f:view transient="true">
</f:view>
This way the javax.faces.ViewState hidden field will get a fixed value of "stateless" in Mojarra (have not checked MyFaces at this point). Note that this feature was introduced in Mojarra 2.1.19 and 2.2.0 and is not available in older versions.
The consequence is that you cannot use view scoped beans anymore. They will now behave like request scoped beans. One of the disadvantages is that you have to track the state yourself by fiddling with hidden inputs and/or loose request parameters. Mainly those forms with input fields with rendered, readonly or disabled attributes which are controlled by ajax events will be affected.
Note that the <f:view> does not necessarily need to be unique throughout the view and/or reside in the master template only. It's also completely legit to redeclare and nest it in a template client. It basically "extends" the parent <f:view> then. E.g. in master template:
<f:view contentType="text/html">
<ui:insert name="content" />
</f:view>
and in template client:
<ui:define name="content">
<f:view transient="true">
<h:form>...</h:form>
</f:view>
</f:view>
You can even wrap the <f:view> in a <c:if> to make it conditional. Note that it would apply on the entire view, not only on the nested contents, such as the <h:form> in above example.

Check if session exists JSF
Session timeout and ViewExpiredException handling on JSF/PrimeFaces ajax request
Unrelated to the concrete problem, using HTTP POST for pure page-to-page navigation isn't very user/SEO friendly. In JSF 2.0 you should really prefer <h:link> or <h:button> over the <h:commandXxx> ones for plain vanilla page-to-page navigation.
So instead of e.g.
<h:form id="menu">
<h:commandLink value="Foo" action="foo?faces-redirect=true" />
<h:commandLink value="Bar" action="bar?faces-redirect=true" />
<h:commandLink value="Baz" action="baz?faces-redirect=true" />
</h:form>
better do
<h:link value="Foo" outcome="foo" />
<h:link value="Bar" outcome="bar" />
<h:link value="Baz" outcome="baz" />

Have you tried adding lines below to your web.xml?
<context-param>
<param-name>com.sun.faces.enableRestoreView11Compatibility</param-name>
<param-value>true</param-value>
</context-param>
I found this to be very effective when I encountered this issue.
First what you have to do, before changing web.xml is to make sure your ManagedBean implements Serializable:
#ManagedBean
#ViewScoped
public class Login implements Serializable {
}
Especially if you use MyFaces
Avoid multipart forms in Richfaces:
<h:form enctype="multipart/form-data">
<a4j:poll id="poll" interval="10000"/>
</h:form>
If you are using Richfaces, i have found that ajax requests inside of multipart forms return a new View ID on each request.
How to debug:
On each ajax request a View ID is returned, that is fine as long as the View ID is always the same. If you get a new View ID on each request, then there is a problem and must be fixed.
I resolved this problem in JAVA EE 8 using AjaxExceptionHandler tag of Primefaces this is available from Primefaces 7 or higher (i am using and test in 11 version). Is so easy and you can combine this with a custom ExceptionHandlerWrapper as BalusC suggests. Use onShow event like this if you need that the page reload are auto.
<p:ajaxExceptionHandler type="javax.faces.application.ViewExpiredException"
update="viewExpiredDialog"
onexception="PF('viewExpiredDialog').show();" />
<p:dialog id="viewExpiredDialog" header="Session expired"
widgetVar="viewExpiredDialog" height="250px"
onShow="document.location.href = document.location.href;">
<h3>Reloading page</h3>
<p>Message...</p>
<!--Here, you decide that you need-->
<h:commandButton value="Reload" action="index?faces-redirect=true" />
Reload.
</p:dialog>
Add this configuration to faces-config.xml file. See ExceptionHandler and Error Handling
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.3" xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

And Voilà this works like clockwork. Regards.
You coud use your own custom AjaxExceptionHandler or primefaces-extensions

I was getting this error : javax.faces.application.ViewExpiredException.When I using different requests, I found those having same JsessionId, even after restarting the server.
So this is due to the browser cache. Just close the browser and try, it will work.
When our page is idle for x amount of time the view will expire and throw javax.faces.application.ViewExpiredException to prevent this from happening
one solution is to create CustomViewHandler that extends ViewHandler
and override restoreView method all the other methods are being delegated to the Parent
import java.io.IOException;
import javax.faces.FacesException;
import javax.faces.application.ViewHandler;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;
public class CustomViewHandler extends ViewHandler {
private ViewHandler parent;
public CustomViewHandler(ViewHandler parent) {
//System.out.println("CustomViewHandler.CustomViewHandler():Parent View Handler:"+parent.getClass());
this.parent = parent;
}
#Override
public UIViewRoot restoreView(FacesContext facesContext, String viewId) {
/**
* {#link javax.faces.application.ViewExpiredException}. This happens only when we try to logout from timed out pages.
*/
UIViewRoot root = null;
root = parent.restoreView(facesContext, viewId);
if(root == null) {
root = createView(facesContext, viewId);
}
return root;
}
#Override
public Locale calculateLocale(FacesContext facesContext) {
return parent.calculateLocale(facesContext);
}
#Override
public String calculateRenderKitId(FacesContext facesContext) {
String renderKitId = parent.calculateRenderKitId(facesContext);
//System.out.println("CustomViewHandler.calculateRenderKitId():RenderKitId: "+renderKitId);
return renderKitId;
}
#Override
public UIViewRoot createView(FacesContext facesContext, String viewId) {
return parent.createView(facesContext, viewId);
}
#Override
public String getActionURL(FacesContext facesContext, String actionId) {
return parent.getActionURL(facesContext, actionId);
}
#Override
public String getResourceURL(FacesContext facesContext, String resId) {
return parent.getResourceURL(facesContext, resId);
}
#Override
public void renderView(FacesContext facesContext, UIViewRoot viewId) throws IOException, FacesException {
parent.renderView(facesContext, viewId);
}
#Override
public void writeState(FacesContext facesContext) throws IOException {
parent.writeState(facesContext);
}
public ViewHandler getParent() {
return parent;
}
}
Then you need to add it to your faces-config.xml
<application>
<view-handler>com.demo.CustomViewHandler</view-handler>
</application>
Thanks for the original answer on the below link:
http://www.gregbugaj.com/?p=164
Please add this line in your web.xml
It works for me
<context-param>
<param-name>org.ajax4jsf.handleViewExpiredOnClient</param-name>
<param-value>true</param-value>
</context-param>
I ran into this problem myself and realized that it was because of a side-effect of a Filter that I created which was filtering all requests on the appliation. As soon as I modified the filter to pick only certain requests, this problem did not occur. It maybe good to check for such filters in your application and see how they behave.
I add the following configuration to web.xml and it got resolved.
<context-param>
<param-name>com.sun.faces.numberOfViewsInSession</param-name>
<param-value>500</param-value>
</context-param>
<context-param>
<param-name>com.sun.faces.numberOfLogicalViews</param-name>
<param-value>500</param-value>

I have been working on Spring security since a year. Today I faced a minor problem regarding Authorization in Spring Security
For intercept url I have configured my spring-security.xml like this
<intercept-url method="GET" pattern="/groups" access="hasRole('VIEW_GROUPS')" />
<intercept-url method="GET" pattern="/admin" access="hasRole('VIEW_ADMIN')" />
This might happen that a user has no role to see /groups page so in that case how can I make sure that user is automatically redirected to /admin page?
I know answer would be simple but I got stuck here.
You could make the redirect in the access denied handler.
Usually you will have something like this in your configuration:
<http ..... >
...
<intercept-url method="GET" pattern="/groups" access="hasRole('VIEW_GROUPS')" />
<intercept-url method="GET" pattern="/admin" access="hasRole('VIEW_ADMIN')" />
...
<access-denied-handler error-page="/access-denied" />
</http>
URL /access-denied usually displays the access denied page. You could register a controller to that URL and then you could check in the controller if user has role "VIEW_ADMIN" and redirect him there. If you need to know which URL user attempted to visit, it should be available in HttpServletRequest object.
EDIT: solution via interceptor:
You could create a Spring MVC interceptor. Extend HandlerInterceptorAdapter and in the preHandle method check if user is authenticated and check the roles and do a redirect.
class MyRoleBasedRedirectorInterceptor extends HandlerInterceptorAdapter {
#Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
//do the authentication/role/URL checks
...
if (needsAdminRedirect) {
response.sendRedirect("admin");
return false;
}
return true;
}
}
And in the config:
<mvc:interceptors>
<bean class="com.example.MyRoleBasedRedirectorInterceptor" />
</mvc:interceptors>
If you dislike original controller solution you can also implement your own AccessDeniedHandler implementation and to the checks there. You would plug in your implementation with
<access-denied-handler ref="com.example.MyAccessDeniedHandler" />
I would still opt for Controller / AccessDeniedHandler solution since, if I understood correctly, redirect happens only when a user is not authorized to visit "groups" page.
I want to know how to redirect the access denied page in spring security?
Shall I use some kind of handler or edit in web.xml?
thanks
Have you read the relevant sections of the Spring Security manual, namely the AccessDeniedHandler and the namespace appendix.
If you want more control, you can use
<http use-expressions="true">
<intercept-url pattern="/denied/*" access="permitAll" />
<access-denied-handler error-page="/denied">
<!-- The rest of your configuration -->
</http>
Where /denied maps to a web controller class which you write. Make sure /denied/** is unprotected.
If this doesn't answer your question, could you please explain in some more detail what you're trying to achieve?
Use a RedirectView for this purpose
Sample
return new ModelAndView(new RedirectView(request.getContextPath()+ "urlPath"), modelMap);
or use the redirect: prefix.
Do you want to redirect the page when a excpetion happens to the page or do you want to redirect the page for secuirty reasons.A handler is required only if there is an exception been occuring to that page.By using a handler we can redirect to our required destination page.Or if you want to redirect to that particular page every time for security we can go for web.xml.
While developing an application it's quite useful to be able to quickly login as different users, with different roles, to see how the application presents itself.
Typing usernames and entering password is no fun, and a waste of time. What I'd like to do is:
add a page/panel with a list of available usernames;
clicking on a username will generate an event for Spring security which allows it to recognize the user as authenticated, without entering passwords;
after clicking the link I am authenticated as the specified user.
N.B.: Passwords are hashed and submitted in plain-text using forms, so encoding the passwords in the links is not an option.
Obviously this feature will only be present at development time.
How can I achieve this?
Use InMemoryDaoImpl for development mode. It is very easy to create users and passwords stored in memory:
<bean id="userDetailsService" class="org.acegisecurity.userdetails.memory.InMemoryDaoImpl">
<property name="userMap">
<value>
admin=admin,ROLE_ADMIN,ROLE_USER
user1=user1,ROLE_USER
user2=user2,ROLE_USER
</value>
</property>
</bean>
In development mode inject this to your authentication provider. In production replace it with the proper DB or LDAP implementation.
I have done it this way for an web application:
I have a configuration parameter in context.xml of the server (of course only in the development server). This parameter contains a coma seperated list of usernames and passwords.
The login page (jsp(x)) simply add a extra form and submit button for each username, password item form the context parameter. So if a user clicks on that button the normal login process with the predefined login data is trigged.
Server context.xml
...
<Context>
...
<Parameter name="quickLogin"
value="admin:passwd,user:otherPasswd"
override="false" />
</Context>
login.jspx
...
<!-- Login for debugging purposes -->
<c:forTokens items="${initParam.quickLogin}" delims="," var="loginPassword">
<c:set var="login" value="${fn:split(loginPassword, ':')[0]}" />
<c:set var="password" value="${fn:split(loginPassword, ':')[1]}" />
<form name="debugLogin" action="${form_url}" method="POST" >
<crsf:hiddenCrsfNonce/>
<input type="hidden" name='j_username' value="${fn:escapeXml(login)}" />
<input type="hidden" name='j_password' value="${fn:escapeXml(password)}" />
<input type="submit" value="${fn:escapeXml(login)} login" />
</form>
</c:forTokens>
...
As I understand you would like to have the SpringSecurity authenticate you automatically if some specific URL is requested (and you would have a link to this URL in your panel/page).
How about writing a custom filter:
public class YourSpecialDevelopmentTimeFilter
extends AuthenticationProcessingFilter
implements SyncSecurityFilter
....
that would override:
protected boolean requiresAuthentication(
HttpServletRequest request, HttpServletResponse response)
and return true depending on some parameters in the request?
Of course another concern is not to have this functionality in the production environments. That is always a risky thing to have different code-base for dev and prod.
I'm doing a project in seam that requires restful URLs. I have a view that is mapped to /group/{group}/{locale}. On that page I have a list of so called messages. Each message has a button to save changes to the message. This is linked to an action bean like this:
<h:commandButton type="submit" value="Save Changes" action="#{groupAction.update}" />
Each message has an anchor, so /group/{group}/{locale}#{id} can be used to make the browser go to that anchor. This is why I need a redirect after the POST:
<page view-id="/group.xhtml">
<rewrite pattern="/group/{group}/{locale}"/>
<param name="group" value="#{groupAction.group}"/>
<param name="locale" value="#{groupAction.locale}"/>
<navigation from-action="#{groupAction.update}">
<redirect view-id="/group.xhtml?group=#{group}&locale=#{locale}##{id}"/>
</navigation>
</page>
Also I have the following redirect rule (UrlRewriteFilter) to get to the proper RESTful URL:
<outbound-rule>
<from>^/group.xhtml\?group=([\.\w]+)&locale=([\.\w]+)\#([\.\w]+)\?cid=(\d*)$</from>
<to type="temporary-redirect" last="true">/group/$1/$2#$3</to>
</outbound-rule>
I strip the conversationId here. This has been tested an works. However seam still appends a '?conversationId={cid}'. So what's the problem? Well, imagine a URL like '/group/{group}/{locale}#{id}?conversationId={cid}'. Oviously the browser doesn't like this and will not automatically go to that anchor.
I did some research and discovered my problem in the seam documentation:
29.1.4.2. Conversation propagation with redirects
This filter allows Seam to propagate the conversation context across browser redirects. It intercepts any browser redirects and adds a request parameter that specifies the Seam conversation identifier. The redirect filter will process all requests by default, but this behavior can also be adjusted in components.xml:
<web:redirect-filter url-pattern="*.seam"/>
I don't need the redirect-filter and I tried putting something invalid in the url-pattern to "disable" the filter. However that didn't work. So my question is now:
How do I disable the redirect-filter in seam?
I can't find the answer. The seam documentation talks about disabling it in web.xml, but my attempts have not been succesful yet.
I've worked out where the unwanted conversationId query string parameter is coming from.
The <redirect/> results in a call to org.jboss.seam.faces.FacesManager.redirect(String viewId, Map<String, Object> parameters,
boolean includeConversationId)
This is called from the following code in org.jboss.seam.faces.Navigator which sets includeConversationId to true:
FacesManager.instance().redirect(viewId, parameters, true);
I cannot see any way to avoid this, so the fix/workaround is to do the redirect programmatically in the action method with:
FacesManager.instance().redirect(viewId, parameters, false);
OK, I managed to kill the redirect-filter by adding this to my compononents.xml:
<web:redirect-filter disabled="true" installed="false" />
However my main problem still exists, so that was apparently not the problem. It still adds the conversationId as an extra query string on the URL. Apperently I'm doing something wrong since it has been done before.
