[NEWBIE Q] redirecting to a certain page if already logged i

[reyjexter]

After successfully validating the account, I'm redirected to the next page which correct but when I try to access the login page again, the login form is displayed. What I want to do here is to redirect the user to another page and not display the login page. I'm using the Identity btw to authenticate the account.

You can use a page action for this - check if the user is logged in, if they are, direct them to a different page.

Hi,

here is a wiki-article about the topic:

http://wiki.jboss.org/wiki/Wiki.jsp?page=AutomaticLoginRedirection

It works but I have the problem, that I get an infinite loop when trying to I enter the application directly calling login.seam page. If I do this an enter my login/passwd the NotLoggenInException is thrown in a loop and the browser displays some kind of redirection error.

What I want is the following:
- call my login.seam page, login and be redirected to the page defined in pages.xml
- if I am logged in and call the login.seam page I want to be redirected to the page defined in pages.xml

Has anybody a working example of the pages.xml to do this? It seems to be a bit tricky and not trivial otherwise this kind of dummy-function in the wiki-article wouldn't be needed. But as mentioned even with this I don't get it working for 100%.

Greetings,

Alexander

How your pages.xml login page is configured?

Does it have login-required="false"?


like:

<page view-id="/login.xhtml" action="#{identity.login}" login-required="false">
 <navigation from-action="#{identity.login}">
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/home.xhtml"/>
 </rule>
 </navigation>
</page>

BTW, you can invoke to any action you want when the page is loaded and then use the rules in order to forward to any page you want.

hey thanks for all the replies.

anyway this is my login.page.xml (just the same as the pages.xml but specifically for login page. i just use this because this is generated by seam-gen):

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://jboss.com/products/seam/pages"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd"
 login-required="false" action="#{userAuthenticator.checkLogin}">

 <navigation>
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/dashboard1234.xhtml"/>
 </rule>
 </navigation>

 <navigation from-action="#{identity.logout}">
 <redirect view-id="/login.xhtml" />
 </navigation>

 <navigation from-action="#{identity.login}">
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/dashboard.xhtml"/>
 </rule>
 </navigation>

</page>

i agree with wachtda that the page action doesnt fire if you try to access the login.seam directly. when i use the base url instead, i am redirected to login.seam and the page action for login page is executed.

Try the following change:

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://jboss.com/products/seam/pages"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd"
 login-required="false" action="#{userAuthenticator.checkLogin}">

 <navigation from-action="#{userAuthenticator.checkLogin}">
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/dashboard1234.xhtml"/>
 </rule>
 </navigation>

 <navigation from-action="#{identity.logout}">
 <redirect view-id="/login.xhtml" />
 </navigation>

 <navigation from-action="#{identity.login}">
 <rule if="#{identity.loggedIn}">
 <redirect view-id="/dashboard.xhtml"/>
 </rule>
 </navigation>

</page>
