I am trying to resolve an apparently simple issue but so far no success. I am developing a web application in JSF 2.2 with PrimeFaces 5.3 and tomcat 8 . I am trying to deal with ViewExpiredException, so that I can redirect the user to index or login page whenever session timeout occurs. I tried adding error-page tag in web.xml to catch the exception and redirect on login page, but no success.

I followed this link (along with several others) to seek guidance but as I mentioned earlier, it did not work for me.

Any help will be highly appreciated.

Below is my application's web.xml file:

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>ricpacs</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping> <context-param> <param-name>primefaces.THEME</param-name> <param-value>#{themeSwitcherView.selectedTheme}</param-value> </context-param> <context-param> <param-name>javax.faces.PROJECT_STAGE</param-name> <param-value>Development</param-value> </context-param> <session-config> <!-- Session idle timeout in min. --> <session-timeout>1</session-timeout> </session-config> <error-page> <exception-type> javax.faces.application.ViewExpiredException </exception-type> <location>/index.jsp</location> </error-page> <context-param> <param-name>primefaces.FONT_AWESOME</param-name> <param-value>true</param-value> </context-param> <mime-mapping> <extension>ttf</extension> <mime-type>application/x-font-ttf</mime-type> </mime-mapping> <mime-mapping> <extension>woff</extension> <mime-type>application/x-font-woff</mime-type> </mime-mapping> <mime-mapping> <extension>svg</extension> <mime-type>image/svg+xml</mime-type> </mime-mapping> <context-param> <param-name>javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE</param-name> <param-value>true</param-value> </context-param> </web-app>

I have tried both values (Development and Production) for PROJECT_STAGE. But that did not help either.

  • Hi Fahim, any reason to don't use the last version of primefaces? Look at primefaces.org/downloads to find the last one. Commented Oct 15, 2017 at 23:35
  • @Doleron, no special reason :-) maybe we will use the latest version in our next project. Thanks Commented Oct 17, 2017 at 10:58

Its always better to study books and detailed guides before implementing something new:-). After reading the PrimeFaces 5.3 user guide, I found out that in order to utilize built-in exceptionHandler feature of PrimeFaces, one must first configure it in faces config.xml file. The configuration is as given below:

<faces-config> . . . <application> <el-resolver> org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver </el-resolver> </application> <factory> <exception-handler-factory> org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory </exception-handler-factory> </factory> . . . </faces-config>

After that, configure web.xml for ViewExpiredException as under:

<web-app> . . . <error-page> <exception-type> javax.faces.application.ViewExpiredException </exception-type> <location>/index.jsp</location> <!-- type whatever suits your environment and requirements --> </error-page> . . . </web-app>

And thats it. Your ViewExpiredException will now be caught by built-in ExceptionHandler.

thank you, I'm using Primefaces and the faces-config changes allowed the web.xml portion to work

Try to use this for capture ViewExpiredException on ajax requests:

<p:ajaxExceptionHandler type="javax.faces.application.ViewExpiredException"

You can add this code to footer section in your template, so you do not have to place it on every page.

Thanks for the reply @C.P.O but It did not work. Anything to mention in onexception or any other argument?
@FahimAshraf It should work, take a look to this: primefaces.org/showcase/ui/misc/exceptionHandler.xhtml
yes, thanks for pointing out. It helped me in understanding my problem and correct approach to solve it. I really appreciate your concern
