JSF Suggestions Needed

[Abiodun Adisa]

I am developing a JSF application where by the navigation is from PageA-->PageB-->PageC . At page A The user signs in. The problem is if a user decides to access Page B with out signing in I want the application to authomatically redirect to PageA so that this user can sign in .
Any Suggestions would be welcome

A filter should do the trick.
Google "Intercepting Filter Pattern"

Can you not just use standard servlet security for this?

    
<security-role>
<role-name>admin</role-name>
</security-role>
 
<security-constraint>
        <web-resource-collection>
        <web-resource-name>Management Functions</web-resource-name>
<url-pattern>/admin/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
 
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/failedLogin.jsp</form-error-page>
</form-login-config>
</login-config>

Hi,

Check for a specific token in the session, if that token is not there, do the redirection, otherwise, do your normal work.

Get a reference to the current instance of the FacesContext, which you use to get an instance of the ExternalContext, which has a method named getSession() that references to the HttpSession object.

Let me know what happens with you ...

Best of luck ...

And one more thing, the ExternalContext contains a method named getResponse(), which actually is the HttpServletResponse, so you can use its sendRedirect() method to do the redirection.

Whenever the user logs in, use the HttpSession object to add an attribute in the session.

Best of luck ...
