15.3.7. Login Redirection

When an unauthenticated user tries to access a particular view or wildcarded view ID, you can have Seam redirect the user to a login screen as follows: 
<pages login-view-id="/login.xhtml">

  <page view-id="/members/*" login-required="true"/> 
... 
</pages>
Copy to Clipboard Toggle word wrap

Note

This is more refined than the exception handler shown above, but should probably be used in conjunction with it.
After the user logs in, we want to automatically redirect them to the action that required log in. If you add the following event listeners to components.xml, attempts to access a restricted view while not logged in are remembered. Upon a successful log in, the user is redirected to the originally requested view, with any page parameters that existed in the original request. 
<event type="org.jboss.seam.security.notLoggedIn">
  <action execute="#{redirect.captureCurrentView}"/>
</event>

<event type="org.jboss.seam.security.postAuthenticate">
  <action execute="#{redirect.returnToCapturedView}"/>
</event>
Copy to Clipboard Toggle word wrap

Note

Login redirection is implemented as a conversation-scoped mechanism, so do not end the conversation in your authenticate() method.
