How to know when a session expires

Hello,
I want to know is there any way to know when a users session ends or when he moves to another site. For example in a Chat to know when a user after logging in just closed his browser window without logging out and then how to remove that users name from our users list.
Is there any event that fires to notify that a user's session has ended and then we can remove his name from logged on users list.

Hi honey jal,
Here I am giving you related url , which tells about chat discussion when session is going to be ends. I hope this one help you out.

How to know when a session has gone by closing browser or leaving site.

Hi! I'm doing an application that uses the session API. This application must run in every java-enabled web-server. I want to know if there is a way to know when a session has gone. I mean, you can know this if, for example, you call the isNew method. But for example, if you close the browser, the session is gone, but obviously, I can't call the isNew method from anywhere, so... how can I know when the session is killed by closing de browser or if the user leaves the site. You can use the onUnload of JavaScript, but I don't want to call a new window when this happens.
Hope you can help me!

You probably can't tell. But then you don't want to do that logic anyway... I was just at your site, and I was signed on, then somebody came in and asked me something so I had to look at another site, then I pressed the back button and now I'm at your site again, but you signed me out? What's with that?

How does c:url tag know when the session is cookieless and thus to redirect

i have been looking at the source code for c:url tag and can't figure out how they are doing that. I need a way to do that in a jsp, to check if the cookies are allowed or not.

how does c:url tag know when the session is cookieless and thus to redirecthuh?
What do cookies have to do with redirecting?
Cookies get encoded into a URL using the method in HttpServletResponse: response.encodeURL() or encodeRedirectURL().
That method determines whether or not it prints out the session id as part of the url, or it gets uses cookies.
You can try: request.isRequestedSessionIdFromCookie().
If that is true, you know that session cookies are supported (or at least that one was)

How to know if a session finished in jsp

Hello,
How to know if a session finished in jsp?
Help me please.
Best Regards.

Depends. You can create a javax.servlet.http.HttpSessionListener implementation and register it in the web.xml file (I forget the syntax, though), which can notify you of sessions being created and destroyed.
Or you can create a javax.servlet.http.HttpSessionBindingListener implementation and add it to the session (setAttribute()) and it'll have it's valueUnbound method called when the session expires (or the attribute is removed, but if you don't remove it, the session invalidating will). That's a good place for session-specific clean-up.

Redirect to main jsp when the session expires

Hi,
I have a jsp say mainframe.jsp in which I have two frames each having a jsp page say child1.jsp and child2.jsp.
When the session expires and I when i try do any changes in child2.jsp or child1.jsp, the page redirects to login page and when I login successfully, I am getting redirected to child2.jsp or child1.jsp respectively. But I want it to be redirected to mainframe.jsp.
Any help is greatly appriciated.
Thanks in advance.
Vinod

I think I am not clear.
When I try to login after session expiry, I am redirected to child jsp.
But what I want is that I should be redirected to mainfram.jsp page.
url in the address shows : ../mainframe.jsp?ID=******
When my seesion is expired and I try do some manipulation in child1.jsp (which is inside a frame of my mainframe.jsp). it is redirected to login page and from there to child1.jsp instead of mainframe.jsp
Now the address url shows : ../child1.jsp?ID=********* because of which I am not able to see child2.jsp along with child1.jsp
What I want : ../mainframe.jsp?ID=********
this is the code I am using !!
String destPage = request.getRequestURI();
response.sendRedirect("../redirect.jsp?dest=" + URLEncoder.encode(destPage));

How to know when the PRICE AFTER DISCOUNT changed and get the value

Hi,
Everything I do to see if a value changed in the grid works except for PRICE AFTER DISCOUNT
which seems to be inaccessible.
Any idea how to know when exactly this value changed and do actions accordinly ?
Also I always get 0.00 if I try to get the value of it
This works to get in the condition of a vlaue changing but I always get 0.00 as the value of the column
if (pVal.ItemUID == "38" && pVal.ColUID == COL_DISCOUNT.ToString() && pVal.EventType == BoEventTypes.et_VALIDATE && pVal.ItemChanged == true && pVal.ActionSuccess == true)
    try
        SAPbouiCOM.Matrix Matrix = (SAPbouiCOM.Matrix)SBO_Application.Forms.ActiveForm.Items.Item("38").Specific;
        SAPbouiCOM.EditText Editor = (SAPbouiCOM.EditText)Matrix.Columns.Item(COL_DISCOUNT).Cells.Item(pVal.Row).Specific;
        SBO_Application.MessageBox("Discount changed for : " + Editor.Value + "...", 1, "Ok", "", "");
    catch (Exception ex)
        SBO_Application.MessageBox(ex.Message, 1, "Ok", "", "");
And this do not even get into the condition even tought I SEE the column PRICE AFTER DISCOUNT:
if (pVal.ItemUID == "38" && pVal.ColUID == COL_PRICEAFTERDISCOUNT.ToString() && pVal.EventType == BoEventTypes.et_VALIDATE && pVal.ItemChanged == true && pVal.ActionSuccess == true)
    try
        SAPbouiCOM.Matrix Matrix = (SAPbouiCOM.Matrix)SBO_Application.Forms.ActiveForm.Items.Item("38").Specific;
        SAPbouiCOM.EditText Editor = (SAPbouiCOM.EditText)Matrix.Columns.Item(COL_PRICEAFTERDISCOUNT).Cells.Item(pVal.Row).Specific;
        SBO_Application.MessageBox("Price after discount changed for : " + Editor.Value + "...", 1, "Ok", "", "");
     catch (Exception ex)
         SBO_Application.MessageBox(ex.Message, 1, "Ok", "", "");

just idea, maybe it will works
Create one udf in row level and set there FS based on changes on price after discount and fill value what is in price after discount. Then the validation make on this field instead of standard SAP field.

How to know when I'm doing a createInsert?

how to know when I'm doing a createInsert, this to hide a button when you run this action, I am using a task flow.
my version of jdeveloper is 12c

hi,
So you are using the createInsert as a method call in task flow. That is your form/table will be come new rows and you want to disable some button.
Your task flow might be as below
      CreateInsert---->Page.
To do so
1.) Take properties of your method call and bind the Method property to a method in a bean (bean registered in the task flow with scope view or any higher scope)
2) Call the create insert operation programmatically in that method.
3) And in that method after the createinsert ,set a boolean variable in pageFlowScope.
4)Put this variable in the disable property or visible propery of the button you wabt to hide/diable.
eg:
    public void doCreateInserOperation(){
        try {
           // Programatically invoke CreateInsert
            DCBindingContainer bindings = (DCBindingContainer)getBindingContainer();
            bindings.getOperationBinding("CreateInsert").execute();
        //Set a variable in page Flow Scope
        AdfFacesContext.getCurrentInstance().getPageFlowScope().put("disableButton", true)
        } catch (Exception e) {
            e.printStackTrace();
    public BindingContainer getBindingContainer() {
        FacesContext facesContext = getFacesContext();
        Application app = facesContext.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesContext.getELContext();
        ValueExpression valueExp = elFactory.createValueExpression(elContext, "#{bindings}", Object.class);
        return (BindingContainer)valueExp.getValue(elContext);
you can access this variable in EL expression as #{pageFlowScope.disableButton}. So when your page render it will be in CreateInsert mode and the button will be disabled/hidden.
I hope this will help you.
With regards,
Gijith.

How to know when the JComboBox popup is about to show or hide?

Hi all,
In JDK 1.4, a new addPopupMenuListener() was added to the JComboBox component. I found out I have to use JDK 1.3, but I already wrote a lot of code around this particular capability. I am trying to figure out how to duplicate it in JDK 1.3. I need to know BEFORE and AFTER the popup is displayed. OR, is there a way with JDK 1.3 that as soon as they click the combo box, it fires an event. The thing is, as soon as they click it, I want to change the background color. When they are done selecting, I can use an ActionListener or ItemListener to find out what was selected and change the color again. My killer is trying to figure out how to know when they have selected the box. I tried adding MouseListener, PropertyChangeListener, AncestorListener. None are doing a thing when the JComboBox is first selected.
Any help would be much appreciated.
Thank you.

How to know when server automatically invalidates session

Hi !!!
I am storing a result set in the session .....
Well there is some need to store result set in the sesssion..I am displaying data in my JSP by retrieving the data from the result set...Now I want to close the connection and result set... when the server invalidates the session ......
Any way to do that???
Reagrd

If objects that you store in session implement HttpSessionBindingListener,
they will be notified by valueBound() and valueUnbound() methods when object
is stored or removed from the session. Object is removed from the session when the session is invalidated, so you can close your db connections from valueUnbound() method. I had the same problem and this works for me.
