Session expired, no logout page displayed

Hi, everyone:
I have been stuck here for a long time. I try to detect session expires and display a logout page.
I tried in the servlet if session.get("username") == null) then forward to logout.jsp, it never reach that page
I also tried using javascript:
<SCRIPT LANGUAGE="JavaScript">
var username = <%=session.getAttribute("username")%>
if (nickname == null)
location.href = 'logout.jsp';
if (parent.frames.length != 0) {
top.location.href = 'logout.jsp';
</SCRIPT>
I never reach the logout page, it display a login page by default. I think the session.getAttribute or value is not working because the session is already expired.
It's such a headache, does anyone has the same problem and find the solution.
I guess it may talke more code either in javascript to detect the session or in a servlet, but how to do it especially if the current pages are in a framesets.
Appreciated any code!!

1)Are the managed servers part of a Cluster? If they are not part of a cluster, then the session replication will not work.
2)Deploy the application to cluster NOT to two managed servers
3)Check the cookie settings - name and domain

Session Expired message when click on page menus

Hi,
I am getting session expired message when click on page menus. I am getting an error saying that "page you are trying to access is no longer active". Please help me in this.
Thanks

When you display the results of you search, is your Servlet writing the HTML out to the screen or is a JSP doing the display?
If the Servlet is doing the work, and you POST to it, you will get that message everytime in IE, and you will get a "repost data?" popup in Netscape. That is because POST data comes up once on the request, and Netscape (i think) is the only browser that remembers the POSTed parameters. You should be able to quick fix this by changing the initial communication with the Servlet to a GET -OR- by having JSPs do the display of the results.
Let me know if you need further help or explaination.

Generating error page(in jsp) when session expires....

hello,
i want to generate error page(in jsp) when session get expires...
plz help me out.............

You could do it according to the line BalusC supplied in another topic:
<meta http-equiv="refresh" content="<%= session.getMaxInactiveInterval() %>;url=login.jsp">The only thing you gotta change, is the URL, make it:
<meta http-equiv="refresh" content="<%= session.getMaxInactiveInterval() %>;url=error.jsp">Create 'error.jsp' and have the message 'Session expired, sorry!' or something printed. If you want to use error.jsp for more than just the session expiration, add a parameter to it:
<meta http-equiv="refresh" content="<%= session.getMaxInactiveInterval() %>;url=error.jsp?error=sessionexpired"> Place the following lines in your error.jsp:
String errormessage = request.getParameter("error");
if(errormessage.equals("sessionexpired")){
out.println("Your session has expired, sorry!");
}else if(errormessage.equals("whatever")){
// To do code here.
}

What are the various ways i can clear my previous(page displayed) session?

what are the various ways i can clear my previous(page displayed) session?

Regarding logout page in jsp and servlets

Hi Friends,
I have created a web page for employee details. When employee enters his details that will be stored in database. Now the problem arises with logout page. When user presses logout, the page is redirected to login page. When he presses back button again its getting logging in for the employee who has just logged in. Can anyone guide me how to resolve this problem. When he presses on back button the page should display with warning message that session has expired. Click here to login. I am posting the code what I have done. And if anyone try to solve using servlets and jsp also no issues. I would be grateful if anyone helps me in advance.

BC4J/UIX: How to implement session timeout and logout?

Hi,
I need to implement logout function in my UIX application. We use JAZN basic authentication. So several things need to be done when user clicks 'logout'
1. Any pending transaction is rolled-back.
2. App Module - what to do with it?
3. Browser closes or redirects to other page. Any attempts to go BACK will show either 'session expired' or will redirect to login page.
Also I need a mechanism where if user is idle for say, 10 minutes, that he/she will be automatically logout (maybe after some warning message). How to do this?
Thanks
Rade

Well if you search long enough, you will find your own answers. After months of not having this solved, I found the solution, in a piece of sample code from oracle that is distro with the OC4J stuff.
if (request.getRemoteUser() != null) {
     // notes that the application is responsible for cleanup
     //invalidate the HttpSession
     HttpSession session = request.getSession();
     session.invalidate();
     String url=null;
     oracle.security.jazn.oc4j.WebSSOUtil.globalLogout(response,url);
     } else      out.println("You are not logged in!");
     out.println("</BODY>");
     out.println("</HTML>");
This is the piece I was looking for, a way to kill off the SSO session. Now when I click logoff, the user is actually logged off the application and their HTTP session is killed off as well.

How to handle session expiration in ATG

Hi,
We have a requirement wherein we have to redirect the user to a specific jsp when his session is expired. For example if a guest user is in cart page and is idle for more than 30 min he should be redirected to session expired page. We are using Apache web server and Jboss app server. Following are the ways i tried
1. In Apache/conf/extra/httpd-vhosts.conf, I have set ErrorDocument 409 to session expired jsp - This is failed because jsp is not a static content and only static contents will be present in webserver. If it would have been a simple html (static) then this method would have worked fine I believe.
2. In cart page I have set the sessionExpirationURL of cartformhandler to appropriate jsp, checkForValidSession to true, CheckSessionExpiration.expirationURL to same session expired jsp. I am not sure why this is not working.
Please let me know the best way to handle this situation. Any suggestions would be appreciated.
Regards,
Avinash

When user clicks any link on your page after session expired then you can redirect him to login page through your formhandler if a handleX() method was invoked by the request or you can use a filter which can check for something like profile.isTransient(). You can then redirect to the login page from your filter keeping a parameter of the original url to be used as login success url so that after login you can again redirect to the page that user originally intended to see.
For detecting user idleness in browser, here is one of the possible approach using javascript by implementing a document level keyboard/mouse listener to detect user interaction in your page:
<script type="text/javascript">
    var t;
    window.onload = resetTimer;
    document.onmousemove = resetTimer;
    document.onkeypress = resetTimer;
    function handleIdleTimedOut() {
        //alert("You are now logged out.");
        window.location.href = 'logout.jsp';
    function resetTimer() {
        clearTimeout(t);
        var timeoutPeriod = 1000 * 60 * 5; //5 minutes
        t = setTimeout(handleIdleTimedOut, timeoutPeriod);
</script>Apart from this, you may also want to take a look at reverse ajax to send the timed out kind of notification to the browser with the help of a HttpSessionListener:

Hope this helps.

Session expired (timeout) without ADF Security using.

Hello!
I have a problem with my application in which i use own security realization without ADF Security using. I realized custom implementation of javax.servlet.http.HttpSessionListener interface, in which i log session creation and expiration events. On WebLogic I realized customDBMS authentification class. Session timeout defined in web.xml (<session-timeout>5</session-timeout>), in weblogic.xml session timeout not define.
Problem description: when session expired (popup warning displayed before this) and press OK button in popup with session expired warning, I see what no any log about session destroying from my HttpSessionListener implementation, so I cant understand, what session expired and process this event in my servlet filter. So I stay at same page (but without data in tables, coz binding variables in VO queries is not defined). If I am not click OK in the popup and wait about minute, then appear a log message about the destroying the session from my HttpSessionListener implementation. Why is the delay between the appearance of warning session expired and the actual destroying of the session in WebLogic?
I use JDeveloper 11.1.1.6.0, application deployed in integrated WebLogic 10.3.5.0

Hi,
Why is the delay between the appearance of warning session expired and the actual destroying of the session in WebLogic?Because warning is given about 2-3 min before session expire
That is why
If I am not click OK in the popup and wait about minute, then appear a log message about the destroying the session from my HttpSessionListener implementation.

Session expired application Webdynpro java

HI:
I am developing an application in WebDynpro Java (J2EE Engine 7.0), which does not run in the portal but is simply displayed on the WAS server.
The problem is I need to catch the exception from the code to not get the error 500: session expired.
I can not change the session time from the properties of the application because it is a customer requirement with 15 minutes session expires.
How I can resolve this?
Thanks and best regards.
Maria Elena

HI:
I've been reading the note and I have a question.
To change the error page, it is in the web.xml, for example:
<error-page>
<error-code>500</error-code>
<location>/customerrors/500.jsp</location>
</error-page>
With this code if I have a 500 error, will launch the jsp (500.jsp).
my question is: where I have the web.xml?
Do I have to develop a J2EE aplicaion or is directly in my WebDynpro application or is on the server?
Thanks and best regards

Session Expired Problem on OAS

Hi,
I often got the error message "Session Expired" displayed on my HTML page that serves Java Servlet output after some time.
I attempted to look through my Servlet source codes but it has no problem. In fact, it runs perfectly well on JavaWebServer2.0.
This seems to be a OAS problem. I'm using Oracle Application Server 4.0.8.1. I attempted changing the Servlet Cartridge's "Max session idle time" and observe the behaviour. It appears that when "Session Expired" problem happened, my servlet class never get called. OAS simply display a "Session Expired" message on the web page.
How can I avoid this? How can ask OAS to call my servlet's doGet() to create a new session when it expired?
Anyone knows how?
null

Hi,
OAS has a limitation of 300 seconds. This value cannot be changed. See the release notes.
One possible way to get around this is to use the Oracle Supplied Session class and use the time feature in that.
This a big limitation and I am not sure why Oracle designed the product this way.
