Question

In our application we use jsf,we have
to redirect the user to home page
after their session will be expired.For that i need a path of the home page which i kept in my logout managed bean as a managed bean property.But after session expired if i try to access that it will arise null pointer exception(managed bean becomes null).Then
i have decide to try alternative (i.e)create logout class manually and try to access the property, at that time the property which i wants to access is become null.How can i access
that property?
Please help me.
Thanks in advance.

In addition to the previous answer:

You could use (in web.xml)

<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>viewexpired.jsp</location>
</error-page>

Or Context Parameters instead of Session Attributes. See:

• http://tomcat.apache.org/tomcat-5.5-doc/config/context.html
• http://safebox.guisho.com/jsf-how-to-get-webxml-parameters

Or use (in faces-context.xml)

<managed-bean-scope>application</managed-bean-scope> 

for your bean, so it will stay independent from the session.
