I have set the session timeout in web.xml to 60 but when I start on the home page and begin to enter any data I immediately get redirected to the timeout page.From the timeout page I can click a link that takes me to the home page. Now I get the 60 minutes before another timeout occurs. Changing the timeout only results in a change to the timeout after going back to the home page..why I am seeing an immediate timeout?
View RepliesMy application uses Struts and IBM Web application Server. I have a question regarding session management. I have a variable stored in session scope, i.e. the name of the client. it is a intranet application. Now whenever the user leaves the browser screen for a long time, the session times out and losses the name of the client.
How to restore the variable after the client comes back and starts using the browser and refreshes the screen and starts using the application. I want just the browser to remember the session variable i.e. "name" of the client.
in my web.xml my session time out is working but not fully working in my ui i use tiles , i have 5 clickable side panels i try to set timeout for 1 minute or 10 minutes for testing after the time is timeout this what happen working refresh the page after time out = working ,directed me into log in page which is correct.i have 5 clickable side panel in my page after timeout when i click the first 2 in side panel tabs it directed me into log in page which is also correct not working after the timeout when i navigate the page i click the other 3 side panels i can still navigate into the page but when i click the first 2 side panel it directed to log in page w/c is correct but can still navigate the page the other 3 side panels
issue : my session timeout is not fully working on my page.

I am new to JSF and I am working on handling session timeout for a JSF application. I am trying to get the code to work for ajax calls and not able to achieve that so far. I have tried two approaches:
Approach 1: SessionListener (for cleanup work) and SessionFilter (for filtering every request and checking if session timed out)
My Code snippet of doFilter() of SessionFilter:
if ((request instanceof HttpServletRequest)
&& (response instanceof HttpServletResponse)) {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
// is session expire control required for this request? (not required for home page or timeout page or JSF resources)
if (isSessionControlRequired(httpServletRequest)) {
[Code] .....
Both these approaches work for non-ajax POST calls but not for ajax calls. When I run my app in debug mode, I can step through all the statements for ajax calls also, which gives me an idea that the control does come to my code, executes it but for some reason, nothing happens on the UI.
I have been trying to redirect user to a timeout page but the ideal thing would be to display a JSF dialog and upon hitting 'OK' take user to Home Screen (My app does not have a login screen.) I have a basic questions also, is view expiring exactly same as session timeout?
Coding a web application using Java 6. Try to implement the session timeout for users.
In the web.xml, I added:
<session-config>
<session-timeout>480</session-timeout> <!-- jsp will expire in 8 hours -->
</session-config>
Now, during the runtime, if a user does not touch the jsp page for 8 hours (after the user has signed in), the session timeout mechanism will kick in. At that point, the server side will automatically execute:
rd = req.getRequestDispatcher("/signin.jsp");
So that the user will have to re-sign in, before continue the work.
How can I achieve this goal?
Generally sessions in web applications expire after a stipulated max inactive interval. To my knowledge primarily the reason is if the session objects are not invalidated they keep exhausting the memory. So my question is
A. Is there any other reason other why web applications timeout the user session after an inactive interval?
B. Social sites never timeout the user session even if you just leave them for the entire day. How do they manage sessions? Don't the active sessions exhaust memory on their servers or JVM to be specific?
I want to implement session timeout functionality ...so with web.xml file i can specify session timeout ..say 30 min.. Now with filter is it possible for me to redirect the request to login page after session is timeout say after 30 min... What are the other ways...??
Also i want to know whether timeout setting in web.xml will overweight the application server timeout ... I am using struts 1.0 and hibernate...
May be I did not understand the meaning and usage of attribute "session" in page directive. My understanding is if session=false, in page directive, then the JSP page will not participate in the session. However, I have my welcomepage as below:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" session="true"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
........
.......
<%= session %>
<c:out value="${pageContext.request.session}"/>
if I choose session=true, then both ways of accessing session works , which means the JSP page participated in the session.
But if I change the session=false, then <%= session %> fails, but <c:out value="${pageContext.request.session}"/> does not fail.
how can c:out still show the session, when session = false
Can I access the session object even session has been expired? I need to check whether session is expired or not for each request.The session invalidation is set null the session object. What I concluded, session time out I can access session object but session invalidation I can not access session object. How can I find the session time out by using session object?
View Replies View RelatedI have 2 war in 1 EAR.
War A corresponds to UI
War B corresponds to Rest
1) From War A, I login to the application and then fetch some users that is a rest call. I get the response back from rest in json form that ui consumes and display the data on page.
2) Now I click on the logout link from ui jsp. This logs out the session from Ui. I use <form data-dojo-type="dijit/form/Form" based logout.
3) I then go to the proxy (using burp) and manually request the rest call which I made in step no 1), the rest gives the response back with the same json object returned in step no 1) This shows that the logout action on step 2) is invalidated the session from War A (ui war) but the session or cookie based from WAR B (rest war) is not invalidated.
Expected outcome:After I Logout from War A(ui war), the session must also get invalidated from war B (rest war) and manually request from proxy should not get the same response object as received in step 1)
I am developing a e-commerce college project, here i add the items in the cart(a div tag in the jsp page) via servlet by creating sessions,
flow control: shopping jsp (when user wants to add an item in the cart) --> item servlet (which is used to create session and synchronized it) --> cart servlet(which is used to add items in the arraylist and show them in the shopping.jsp's div tag + it also sets the total purchase amount in the session variable "totalpurchase")
now after that user wants to proceed to checkout, here i use the onclick event to check the minimumshopping amount must be less than the totalpurchase (totalpurchase which i had setted in the session),but my jsp page is unable to rechognise the updated value of the totalpurchase, yes, if i reload the page, it rechognises the new updated value of the totalpurchase? but i want it to rechognise the updated total purchase value, without reloading he jsp page..
I have a line code like this one:
String result = someHeavyMethod();
and I need to add this logic: "if the method doesn't finish within 10 seconds, cancel it and let me continue with the rest of the program".
I have a method "doSomething" which can take a while to be fully executed.
...
boolean bResult = false;
bResult = doSomething();
System.out.println("Result:" + bResult);
...
I would like to be able to stop the method execution after 10 seconds and continue the normal execution of my class. This means:
- If doSomething() is executed in 3 seconds for example, the System.out.println() statement shows the result of the method
- If doSomething() is executed in more than 10 seconds, after 10 seconds the method is stopped and the System.out.println() will always have false as result.
I'd like to ask is there way to control the RMI lookup timeout through programming or network configurations.
In a testing environment, I have purposely disconnect or plug out the cable between two testing servers to check the reliability.
It took very long time for the RMI API to throw out java.rmi.ConnectException which used Naming.lookup(givenURL).
I have tried to set system properties like sun.rmi.transport.tcp.handshakeTimeout, but it didn't take effect at all.

I have a problem with a JavaScript application on Safari 6 and 7. The application updates a smartcard on a website, through a JAVA applet using JavaScript requests.
There is no problem with other browsers. On Safari , randomly (1 smartcard's update on 10), the javascript completely freezes in the middle of an update (on a random card).
After 5 minutes exactly, the javascript resumes, and 2 behaviors happens : the update wether continues or stops completely.
We investigated a lot about this problem , at network and memory level. We use a lot of "setTimeOut" function (approximately 1100 times), and read that setTimeOut could cause problems with memory management on Safari.
Does setTimeOut can freeze safari ?
I've run in an issue with connection timeout in the WebView. Requesting the URL in a browser will result in an answer, however it may take some time. Running the same request from the WebView results in a connection timeout.
What is the connection timeout for loading a page through the WebView (from issuing the request webEngine.load(url) to the state change failed passes about 40s). The Request in a browser takes about 10s.
Can I manipulate the underlying connection of the WebView (as suggested at java - How to connect to an HTTPS URL from a JavaFX application - Stack Overflow)
Can I set the connection timeout on the WebEngine/WebKit or per request?Is there an issue targeting this?Likewise I would be interested to get a handle on the connection so I can evaluate the header data to retrieve useful information (like response was a PDF which cannot be rendered in the WebView)....
I have a jsp page that generate a hashtable and display its key-value pairs back to the browser. The problem is that it takes on an average about 15 minutes to build this hashtable, and as a result, I always get a timeout error. What can I do to avoid getting the timeout error without changing the server configuration for timeout

I have tried this example ([URL].../) with CarDao extending the BaseDao, it works like a charm.However, from the CarDao class, my NetBeans underlined the class name “CarDao” with the error message “A session bean must not extend another session bean.” But I can compile, deploy and run the application without any problem.
I have also heard that a session bean cannot extend another session bean, but why it works here?

I am using JSF2 with Primefaces. Here is my business requirement-Hidden field on JSF page should take the value from the session object that is set in managed bean. Session object is updated every time when the user submits the page. I am able to update the session object in the managed bean and able to get the value in the hidden field first time and after that i see the same value in the hidden field even though session object has different value. Here is the hidden field: <h:inputHidden id="xyz" value="xyz"/> i tried using sessionScope but still didn't work.
View Replies View RelatedI'm trying to go back to basic and strengthen some of my foundation. I'm wondering what kind of data would be appropriate to be stored inside a session? My app is a web app where all the users are the employee of a company. So it's an web-based app that keeps track of stock movements, purchasing and sales order (standard distributor company). The web app interacts strictly with employees, so no public facing app (yes, that's right, no shopping cart). So, in this kind of web app, what kind of data that by storing it to session.

I am new to JSP and I'm having a problem with captcha containing a value in the field when toggling from the first page to another and clicking submit on the second page before entering data to validate the fields and the code just falls through and returns the error "Please enter the correct code". The values returned are (captcha)96043 (code)null, captcha is not null because it is retrieved from session which is the last value captured from the page I'm assuming.
I've used request.getSession().removeAttribute( "captcha" ); before building the page to clear out the values, resetting captcha to null etc.; nothing is working.
Here's the code:
boolean isPostBack =false;
String captcha = (String) session.getAttribute("captcha");
String code = (String) request.getParameter("j_captcha_response");
[code]....
Is it a good idea to use the date and time with the first or last few values of the session ID. Or should I just use the complete session ID value for my "unique id"?
