Implementing session

I am using the HttpSessionBindingListener to keep track of whether an user
has logged out or has been timed out by the server. I put an object in the
session when the user logs out and check in the unbound event if this object
is there. If it is present, it means the user has logged out and if not, it
means he has been timed out. BUt i am not understanding as where to keep the place the java class in iPlanet\APPs\myapplication.Can anyone tell me about how to proceed

Also is there any way to purge the current session by running background DBMS_JOB so that after some time interval it will show not get the session to hold and redirect to the login page again...

Implementing session handling in servlet controller

how to implementing session handling in servlet controller.
instead of writing isNew() in every jsp page i wanted to write in my central controller ,where each request is passing through controller. can any body give me the solution

i tried it it is failed because first time the request is coming to the controller.it checks for new since of it is a first request it is forwarded to the login page.how to avoid or skip the condition checking when the request is first time.

How to implement session listener in RM

Hi,
In my repository manager, a connection to another system is established when a user tries to access the repository. Is there any way to implement a session listener, thereby terminating the sessions to another system when the EP user logs off?
In our words, in Repository Manager, how can I know when an EP user clicks Log off?
Thanks,
Ray

Or, how can I know when a user logs off EP in my repository manager?

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.

Implementing Session in flex (Store an object in Session)

Hi All,
Is it possible to store an array collection in session ? How can this be implemented ?
Thanks

Have the password visible??? Why??? All you have to do is to capture the password that the user typed in and pass it as a variable to the connection string.
Say, if you are using the JDBC:ODBC bridge, it will be something like this:
Connection con = DriverManager.getConnection(
url, login, password);
//where url, login, and password are all variables.
Hope this helps.

Strategies on implementing session synchronization from different browser

I need some ideas on how to implement singleton pattern to track for existing user session upon successful authentication? If a user logs in from one machine and then from another, the newer session should be used while the older one is invalidated. Can anyone provide me with some documentation or ideas on how to accomplish this?
thanks,
Wes

Hi,
what about setting a cookie to the user browser? If the cookie indicates a different session ID than what is read in the session, close the current session. Upon application start (user authentication) you set the cookie to the current session ID

Implementing session timeout in JSP - - Urgent help !

Hi
I have a requirement where I need to write a session timeout functionality in a JSP such that the page is redirected to a different page if there is no activity for 5 min.
I tried the following :
1.On the onload of my JSP, i created a new session from the current request using the following code snippet :
          HttpSession pSession = request.getSession(true);
          pSession.setAttribute("loggedin","true");
          pSession.setMaxInactiveInterval(10);
2. Then on any action performed on the JSP, i called the collowing JS function before invoking the server side code.
/** function to check the user session **/
function fnChkSession()
     alert('Inside check session');
     <%
          try
               System.out.println("The value of the session var loggedin : "+pSession.getAttribute("loggedin").toString());
               System.out.println(" getMaxInactiveInterval() value is : "+pSession.getMaxInactiveInterval());
          catch (Exception e)
               System.out.println("** Inside the fnChkSession exception catch block **");
          if (pSession.getValue("loggedin") == null)
     %>
          alert('Session has expired');
          document.forms[0].submit();
     <% } %>
But when I execute this code ,even after 10 secs my session seems to be alive.I can retrieve the session attribute after 10s.
I also tried setting the session-timeout value in the web.xml. It didnt work.
Can anyone pls help me on how to proceed further on this.
Thanks

You are confusing java with javascript.
These two things are not the same.
The lifecycle goes something like this
1 - Request is made to server
2 - Java/JSP runs java code, produces HTML page
3 - java stops running
4 - html is sent to browser, and javascript starts running.
You cannot call java code from browser events (such as onload, onclick, onchange...) The only way to run java code again is to submit a request (normally by submitting a form, or clicking a link. )
If you want a javascript solution, in IE, use the window.setTimeout() method to execute some javascript code after a certain period of time.
A more generic approach would be to use the refresh header. Set the timeout for the refresh header to be 300 seconds. If the user stays on the same page for more than 5 minutes, it will redirect to the new page.
Hope this helps,

How FF can become smarter about implementing Session Restore

FF needs to become "smarter" about Restoring. Only do a chunk of say 10 tabs at a time, and improve the error recognition & handling so it doesn't just spin forever. Sometimes it doesn't even show the spinner; just won't respond & Activity Monitor says its Not Responding. Can't tell if the Not Responding is due to an active but CPU stealing process that is proceeding, or a stuck process where I should Force Quit. Just have to let it go for 10 minutes before Force Quit.
Restore needs to have a popup window that tells me exactly what tab it is actively Restoring at the moment, and a timer showing how long it was been working on that Tab. And I need to be able to tell FF how long to try before abandoning that Tab. I need to be able to tell it to abandon that tab sooner via a click button. Abandoned tabs go into a menu for me to mess around with later.
Noticed that mozilla.org is often "on top" when FF hangs up. And just now, navigating from the main mozilla page to here (3 layers deep?) I had to wait 5-10 seconds for each page to load. Is the mozilla server just underpowered for the amount of traffic, or what?

''Why should I want to decrease that?''
I said to look at the settings. I did not say to change anything.
''When I got the email notification, I went to this tab and Refreshed it to see your reply''
You left the page on the browser after you sent your post? Why is that?
Are you doing this with your other trouble web pages?
Do you have this problem when you use a link or bookmark?

How to implement a Session Object.

Hi,
If anybody show me any example of how to implement
session object so that I can store any parameters such as user id and use it later on. And also if there is any good web site for reference about using session object.
thanks

You can use the the session.setAttribute and session.getAttribute methods.
For example let's say you would want to store a username in the session after a user has logged on:
String usrname = request.getParameter("username");
session.setAttribute("myStoredUsername", usrname);
you can then retrieve it using the get method. Remember that the entities stored inside a session object are generic objects and need to be cast to be used:
String usrname2 = (String)session.getAttribute("username");
Hope this helps

Problem in implements ADF Faces: Detecting and handling user session expiry

Hello everybody
I´m trying to implement a method to handle user session expiry as explained by frank nimphius in his blog.
http://thepeninsulasedge.com/frank_nimphius/2007/08/22/adf-faces-detecting-and-handling-user-session-expiry/
I have implemented the class bellow and add the filters in web.xml. However when I add the JavaServer Faces Servlet to sign the filter, my hole application get nuts. I try to publish the applicatoin in the OAS and it seems that it already starts expired.
Someone konw what I´m doing wrong?
I use the filter
<filter>
<filter-name>ApplicationSessionExpiryFilter</filter-name>
<filter-class>adf.sample.ApplicationSessionExpiryFilter</filter-class>
<init-param>
<param-name>SessionTimeoutRedirect</param-name>
<param-value>SessionExpired.jspx</param-value>
</init-param>
</filter>
then I add
XML:
<filter-mapping>
<filter-name>ApplicationSessionExpiryFilter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
package adf.sample;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
this is the class
public class ApplicationSessionExpiryFilter implements Filter {
private FilterConfig _filterConfig = null;
public void init(FilterConfig filterConfig) throws ServletException {
_filterConfig = filterConfig;
public void destroy() {
_filterConfig = null;
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
String requestedSession = ((HttpServletRequest)request).getRequestedSessionId();
String currentWebSession = ((HttpServletRequest)request).getSession().getId();
boolean sessionOk = currentWebSession.equalsIgnoreCase(requestedSession);
// if the requested session is null then this is the first application
// request and "false" is acceptable
if (!sessionOk && requestedSession != null){
// the session has expired or renewed. Redirect request
((HttpServletResponse) response).sendRedirect(_filterConfig.getInitParameter("SessionTimeoutRedirect"));
else{
chain.doFilter(request, response);
I'm really having trouble controlling user sessions. if someone know where I can get materials to learn how to implements session in Jdev ADF + BC, I´m very grateful.
Thank you Marnie

The class works fine.. the issue is when I add the this code into web.xml

Thanks in advance

I'm not using Flex, but the following preserves session in Flash:

How to implement the Session ManageMent in OracleADF .

Hi I am New to ADF, In my application i have requirement like, I Have a JSPX login page,which contain 4 taskflows as a regions(like AddEmp,DeleteEmp,Create New Dept,Delete Emp), based on the type of user login,i want give different responsibilities(ADF Security, for example a normal employe cant Edit the Other Employe information only HR can do the Edit ), for those who logged in i want to use Session.
Every Time When the user Request the resource it has to check for the session validation.
i know in JEE How to implement Sessions but i don't know in ADF .
Thanks in Advance...

Hi,
have a look here http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/AdfSecurity/AdfSecurity.html
Its a video about ADF Security that explains how you can use custom Resource Permissions for any kind of user authorization, plus the on-board page and task flow permission. Note that the session has nothing to do with authorization. All a session can be is authenticated after which users are associated with enterprise roles, which then are mapped to permissions (through application roles in ADF Security). So session management is not what you are looking for in this case.
In addition you want to read: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/76-insert-update-entity-protection-334421.pdf

How sessions are implemented on server

Hi All,
Can anyone please tell me how sessions are implemented on server like JRun, WebLogic, WebSphere or in general ?
Thanks & Regards,
Kumar.

A common way to implement sessions in web servers would be something along the lines of...:
1) When a browser accesses the webserver, the webserver sends a cookie with a session id to
the browser.
2) The webserver creates an instance of some proprietary class that implements the
javax.servlet.http.HttpSession interface (comes with J2EE)
3) The webserver stores the session instance in a java.util.Map instance using the session id as the key.
4) When the browser hits the web server again, the cookie containing the session id is also sent, and
the web server knows which session instance to use when processing this request.
5) If the browser doesn't have cookies enabled, URL rewriting can be used. URL rewriting means that
the webserver adds the session id as a parameter to every link in the web application. Thus, whenever
the browser accesses the server again, the session id will be part of the URL, and the web server will
know what session instance to use when processing the request.
6) The webserver has a thread checking the session instances regularly to see if they are still valid,
meaning if their timeout limit hasn't been passed since the last request. If a session has expired it will
be removed. If a browser accesses a server with an old session id, the server will send a new cookie
with a new session id to the browser.
7) If the web server is part of a cluster, the session instance must be stored in a central database so all
web servers can access it, or the session must be replicated from the current server to all other servers in the cluster, whenever the values in the session instance changes.
Though I'm not an expert on Java web servers, I believe the, or variations of the above of course, will be how it's done.
Hope this gives you an idea.

SSO Partner Application and Session Time out

Hi ,
We have an application on forums.oracle.com which is implementing the Authentication scheme as SSO, that is working well, now we want to implement Session Time out if the user is idle for some time and ask him to login again after the session fails, I have tried to implement this feature as given by Scott in the thread session timeout , well the problem is since we dont have a login page here how do we set the cookies owa_cookie.send(
name => 'HTMLDB_IDLE_SESSION',
value => to_char(sysdate+(20/1440),'DD-MON-YYYY HH24:MI:SS'),
expires => null,
path => '/',
domain => null
and where is the current point to implement it.
Any help on this is greatly welcome.
Thanks in Advance.

Naveen,
I don't remember how the solution works. But if you don't have a login page you can usually put code in the post-authentication process of your authentication scheme to do whatever the login page process would have done.
