Session tracing with HttpSessionBindingListener

Hi,
I hope someone can help.
I am an Oracle developer/ assis,. dba looking at the possiblilties of Servlet and JSP's as
front end apps for my databases.
I'm trying to call an event when a session invalidates but i am having great difficulty whith
getting HttpSessionBindingListenerto be called.
Here is my test system.
this is just one method of using the HttpSessionBindingListener
i have also even thrown the RunTimeException without no effect.
import java.io.*;
import javax.servlet.http.HttpSessionBindingListener;
import javax.servlet.http.HttpSessionBindingEvent;
public class sessLsnr implements HttpSessionBindingListener, Serializable {
String _path = new String("c:\test.txt");
public sessLsnr() {
public void valueBound(HttpSessionBindingEvent event) {
try {
File file = new File(_path);
if (file.exists()) {
     FileOutputStream out = new FileOutputStream(_path);
     ObjectOutputStream s = new ObjectOutputStream(out);
     s.writeObject(this);
     s.flush();
s.close();
out.close();
catch (Exception e) {
e.printStackTrace();
public void valueUnbound(HttpSessionBindingEvent event) {
try {
File file = new File(_path);
if (file.exists()) {
     FileOutputStream out = new FileOutputStream(_path);
     ObjectOutputStream s = new ObjectOutputStream(out);
     s.writeObject(this);
     s.flush();
s.close();
out.close();
catch (Exception e) {
e.printStackTrace();
and the initial servlet.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class testlsnr extends HttpServlet {
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response)throws ServletException, IOException{
processRequest(request, response);
public void doPost(HttpServletRequest request,
HttpServletResponse response)throws ServletException, IOException{
processRequest(request, response);
protected void processRequest(HttpServletRequest request, HttpServletResponse response){
HttpSession session = request.getSession(true);
session.setMaxInactiveInterval(150);
sessLsnr _lsnr = (sessLsnr) session.getAttribute("test");
if (_lsnr == null) {
_lsnr = new sessLsnr();
session.setAttribute("test", _lsnr);
Please can someone help as from the documentation i have read and examples i have seen i think that i have got it right but with it not been called there is something wrong.
Many Thanks

In A JSP Page
for example:
<html>
<%@ page language="java" import="java.sql.*;" %>
<jsp:useBean id = "Conn" scope = "page" class = "package.class file name" />
<%
Assuming the SESSIONVALUE - session variable is intialised previuosly in a JSP Page.
String ChkSession = (String)session.getValue("SESSIONVALUE");
if(ChkSession != null) {
execute the code when the session value is true (you can redirect the page or include the pages according to your requirement)
else {
execute the code when the session value is false - expired (you can redirect the page or include the pages according to your requirement)
%>
</html>
This may be helpful, if you have any doubts feel free to ask me

Problem with HttpSessionBindingListener

Hi
I have a problem with HttpSessionBindingListener.
The sesion timeout in web.xml is 10 min.
I open sesion 1 at 10:00 am
I open sesion 2 at 10:05 am
The valueUnbound method is called twice at 10:15 am
The problem is that the valueUnbound is fired only when the last sesion on the site gets timeout. If the example worked well:
The valueUnbound would called would be fired at 10:10 am (sesion 1)
The valueUnbound would called would be fired at 10:15 am (sesion 2)
The example code is very easy:
public class ususs extends java.lang.Object implements HttpSessionBindingListener
     private String userName;
public ususs(String userName) {
this.userName=userName;
     public void valueBound(HttpSessionBindingEvent event)
          userName="kk";
     public void valueUnbound(HttpSessionBindingEvent event)
               userName="";
... And request.getSession().setAttribute("oUsuss", new ususs("myuser")); when the user logins
Thanks

The ConnectionCloser code:
public void valueBound( HttpSessionBindingEvent event )
     System.out.println( "[ConnectionCloser::valueBound]" );
public void valueUnbound( HttpSessionBindingEvent event )
     System.out.println( "[ConnectionCloser::valueUnbound]" );
}The login method, session.setAttribute should invoke valueBound in ConnectionCloser
private void login( HttpServletRequest, HttpServletResponse)
     throws ServletException, IOException
     HttpSession session = request.getSession( true );
     Integer oTilr = (Integer)session.getAttribute("tilr");
     if( oTilr!=null && oTilr.intValue()>MAX_TILRAUNIR )
          villubodTilNotanda( "Of margar ....
     else
          try
               Connection cTengingNotanda = Vinnsla.login(...
               session.setAttribute( "tn", cTengingNotanda );
               sendaSvar( "Innskr?ning t?kst" );
          catch( Exception e )
               Integer oT2 = null;
               if( oTilr!=null )
                    oT2 = new Integer(oTilr.intValue()+1 );
               else
                    oT2 = new Integer( 1 );
               session.setAttribute( "tilr", oT2 );
               villubodTilNotanda( "Sennilega ...", response );
}The logout method: session.invalidate() should invoke valueUnbound in ConnectionCloser
private void logout( HttpServletReq. request, HttpServletResp. r )
     throws ServletException, IOException
     HttpSession session = request.getSession();
     if( session == null )
          villubodTilNotanda( "?? ert ekki innskr??(ur)...
     else
          session.invalidate();
          skilabodTilNotanda( "?tskr?ning t?kst", response );
}thanks again,

Vi session strategy with LV 7 in Test Stand

Hi all, Im a producing a set of vi's(LV7.1) which will be strung together in a Open Visa, Write visa ..., Read visa , Close visa, over several instruments.
I wish later to use Test Stand(3.1) to slice these routines, but I am not sure how test stand handles the session references when I break the flow.
Im thinking of a first step that initialises all instruments , then later steps that grab the session references and perform tests.
Do I need to store the sessions as varables in Test Stand?, or is there a better way?.Is there any examples that cover this topic?
thanks

I guess that a better way is NI Session Manager.
NI Session Manager is the software component (of NI TestStand) from which you obtain instrument sessions. Session Manager returns a reference to the session object with the name you specify. If the session object you specify does not yet exist, Session Manager creates it and returns a reference to the new session.
Session Manager also allows you to close all opened sessions automatically.

Set Session State with Shuttle items

Is it possible to have session state set with each item selected in a shuttle? You have a shuttle with 4 possible options, you select item 2 from the left portion of shuttle and it is moved to the right.. Can you set the session state at that point?
What I am trying to do is take the session state after change in the control and use it to populate a text field below. The returned values are used in a sql select to populate the text box with a looked up value...
Thank you,
Tony Miller
Ruckersville, VA

TexasApexDeveloper wrote:
Won't this just push the last items value in, as apposed to appending the value?
Tony,
No. Because for shuttle items the return value is stored as colon delimited string.
Means after each change you will have a colon delimited string in the session state with selected values(moved to right).

Synchronizing persistent tmux loginctl session ID with new session

Hey all. Does anyone else have the issue with a persistent tmux session losing it's 'active' session status with loginctl after restarting the window manager (monsterwm in this case, logging in automatically on VT1 per the wiki)? This causes issues with udisks mounting priviliges. I'd think it'd cause issues with pulseaudio but it doesn't (and I don't understand why).
So, to reproduce:
1. Fresh reboot and login
2. Open terminal. $XDG_SESSION_ID will be 1
3. Open tmux instance. $XDG_SESSION_ID will be 1
4. Restart the window manager
5. Open terminal. $XDG_SESSION_ID = 3. loginctl session-status active=yes
6. Reattach tmux session. XDG_SESSION_ID =1. loginctl session-status active=no
Is there some easy way to keep these synchronized so I don't have permissions issues?
Thanks!
Scott

No, it has nothing to do with host names, CNAME, DNS or anything.
The session ID is sent to the server from the browser in either a cookie header or as part of the "extra info" part of a URL with the request. If there is no session ID in either place, the server creates a new session. If there is a session ID, then it gets the session object (if it's not expired). Then it sends the session ID back to the browser with the response to that request (either as a cookie or encoded into the URLs in the page, which you have to do explicitly do for each URL). Click on a link, then the process starts again. The first time you go to a site, you have no session ID. The server just makes a new one.
The only thing that domain names have any affect on is cookies. Cuz cookies are name/value data associated with a domain name of the server (amongst other things). The browser, for security reasons, only sends cookies in requests to servers that set the cookie in the first place. The server can't get cookies that it didn't set.
So if you have a server running on your local machine, you can access that server in 3 ways:
1) localhost
2) network name
3) domain name
The browser can know quite easily that 1 and 2 are the same thing, and send cookies for either interchangably (not that it has to, but it seems you are seeing this happen, so...). But the browser will probably not make any assumption about 3's relation to 1 or 2. The association is generally to domain name, not necessarily IP address.
And it's really a moot point anyway. You should not typically be accessing a server from those 3 different means within the same session. Someone connecting to your server isn't going to use anything but #3 anyway, the other 2 (definitely #1 and #2 only works on the same LAN) wouldn't make much sense. So there's not going to be this issue at all. The session ID itself has no relation whatsoever to a client's domain name.

ODI-1217 session fails with return code 904

Session control with multiple web servers in IE

to understand my problem do the following:
make a page with this code:
<%
out.println("sessionID = "+session.getId());
%>
Run two (2) instance of web servers (can be a tomcat) in different ports...
open IE and access the URL: http://localhost:8080/test/mytest.jsp
see id number...
access http://localhost:8081/test/mytest.jsp
see id number...
now access http://localhost:8080/test/mytest.jsp again
and will see that IE lost the session and has a different session id.
if you make this test in Nestcape it will keep the same session id when you access the 8080 server again, and is what i want :)
anybody knows a solution to this?
in the real world, my application has a frame with a menu that runs in 8080 server port and the application that are called by this menu will run in different ports in another frame. the problems is that when a call a application in another port, with IE i lost the session from the menu that runs on port 8080. With Netscape work perfect!
somebody can help?

this seems to have to do with the handling of sessoin cookies. IE creates one cookie for every browser instance whereas Netscape creates one session cookie for all browser instanced. Linke this Netscape shares a session cookie with the whole application wheres as IE does not.
Just to make it clear: none of the both handling methodes are right or wrong. In my opinionen from the point of security, the IE solution is better.
The only workaround i see is to implement a session id your own. Store it in the session object and the session object into a session manager that can be accessed from both application.

No session found with status "New" or "Error"

Hi,
I put the statement after the CLOSE GROUP to process the BDC automatically:
SUBMIT RSBDCSUB AND RETURN
         EXPORTING LIST TO MEMORY
         WITH MAPPE = SESSION.
         WITH VON = SY-DATUM
         WITH BIS = L_NEXT_DAY
         WITH Z_VERARB = 'X'
         WITH FEHLER = ' '.
And when I ran it I got an error that says
<i>No session found with status "New" or "Error"</i>
When I go to SM35, I see the session in the 'New' tab. How can I get this to process completely without manual intervention or first thing first no error from running the program?
Thanks,
Will

Replicated session state with WLS 5.1 sp 6 in cluster

          Hello, i've seen in BEA documentation this:
          Applications Using Frames Must Coordinate Session Access
          If you are designing a web application that utilizes multiple frames, keep in mind
          that there is no synchronization of requests made by frames in a given frameset.
          For example, it is possible for multiple frames in a frameset to create multiple
          sessions on behalf of the client application, even though the client should logically
          create only a single session.
          In a clustered environment, poor coordination of frame requests can cause unexpected
          application behavior. For example, multiple frame requests can "reset" the application's
          association with a clustered instance, because the proxy plug-in treats each request
          independently. It is also possible for an application to corrupt session data by
          modifying the same session attribute via multiple frames in a frameset.
          To avoid unexpected application behavior, always use careful planning when accessing
          session data with frames. You can apply one of the following general rules to avoid
          common problems:
          ·     In a given frameset, ensure that only one frame creates and modifies session data.
          ·     Always create the session in a frame of the first frameset your application uses
          (for example, create the session in the first HTML page that is visited). After the
          session has been created, access the session data only in framesets other than the
          first frameset.
          My environment is clustered(multi-tier) and jsp and servlets use frameset, could
          you explane this?
          I don't understand very well
          Thanks and regards
          Fabio


          Thanks for you suggest!

Stateful Session Bean with BMT: JDBCpmf or EEpmf?

Quote:
For the record: when using BMT as David described, you should use a JDBCPersistenceManagerFactory
instead of an EEPersistenceManagerFactory. EEPersistenceManagerFactory is only appropriate when
transaction synchronization is desired.
-Patrick
Hi Patrick,
I wanted to follow up on this. In the case of Kodo, the JDBCpmf does not turn on the
UserTransaction in a managed environment, while the EEpmf does. My question: isn't is necessary to
turn on the UserTransaction in a stateful session bean with BMT? If this doesn't happen, isn't
there a danger, if the bean allows transactions to span business method invocations, that the
container will passivate the bean while a transaction is active? Since the PM can't be saved during
passivation, the tx would be interrupted by passivation -- something that would not happen if the
container were aware that a tx was active.

David,
My interpretation of your initial post was that you were using fully
unmanaged transactions in your bean. That is, that you were not using the
UserTransaction, but were just using the javax.jdo.Transaction for
transactional data store access.
In the situation I just described, using the EEPMF would result in changes
to the UserTransaction. If your goal was to manage the UserTransaction in
the bean, then yes, you'd still want to use the EEPMF.

Any help is highly appreciated...

Hi Khalid,
Are you still just getting 26Bs continuously?
What policy have you configured on the server?
Also, 5.2 is old too, you should be running 5.4.1 if this is a new system.

Associate Session ID with Client ip for improved security

Hi,
Id like to know if it's possible to associate session id with some more info like client's ip address and user agent, to ensure that no one can access my app by cookie injection.
Do anyone knows what's the best/recomended/iWouldDoThisIfIWhereYou approach?
Thanks!

I don't think I've seen anything like this with WebLogic Server. I think the right approach in this case is to use SSL with httpOnly (default) and then unless someone has local access to your machine or the remote server (you have bigger problems!) then they can't hijack your session with a man-in-the-middle.
You can email me at my user id at oracle.com if you have a concrete requirement.

Session Tracing tab is missing.

Dear ISA Experts,
I am using ISA 5.0. When I goto logging in Admin, The session tracing tab is missing. Appreciate any pointers to display the session tracing tab to trace the session log.
Thanks!

Thanks Mark for your reply. My Java core is on SP14. SAP-SHRWEB, SAP-SHRAPP & SAP-SHRJAV are on SP11 & 12. I have gone through the note : 1090753 and noticed that the following parameters are already set.
'appinfo' and 'logfiledownload' parameters to 'true'
ForceSingleTraceFile to 'No'.
When I goto : http://hostname:50000/b2b_xyz/admin/index.jsp and logging, I see only Log configuration and not "Session Tracing". Please advice.
Thanks!
Surya.

New session started with an advertizing page and all my tabs are lost

New session started with an advertizing page and all my tabs are lost. Restore the previous session is not active. How can I restore my tabs?

This advice might come too late, but, don't exit Firefox! Or if you already did, don't start it back up again!
''If Firefox is running:'' Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
* type or paste about:support in the address bar and press Enter
In the first table on the page, click the "Show Folder" button. This should launch a new window listed various files and folders. For best results, change the view to "Details".
(''If Firefox not running, get to this folder by pasting the following in the Run box on the start menu and pressing Enter: %APPDATA%\Mozilla\Firefox\Profiles and then double-click into the most recently updated semi-randomly-named folder you find there.'')
In the window that launches, scroll down and double-click into the '''sessionstore-backups''' folder. Save all files here to a safe location, such as your Documents folder, so Firefox doesn't overwrite them. We may be able to use them to recover your lost tabs.
Also, if you return to the main level of the profile folder, you may find some sessionstore files. Copy those to the safe location as well.
Could you report back on what you found?
Note: If Windows hides the .js file extension from you, you can change a setting so that you can see all file extensions (this helps when renaming files). This support article has the steps: http://support.microsoft.com/kb/865219 or http://windows.microsoft.com/en-us/windows/show-hide-file-name-extensions
The kinds of files you may find among your sessionstore-backup files are:
* recovery.js: the windows and tabs in your currently live Firefox session (or, if Firefox is closed, your last session)
* recovery.bak: a backup copy of recovery.js
* previous.js: the windows and tabs in your last Firefox session
* upgrade.js-''build_id'': the windows and tabs in the Firefox session that was live at the time of your last update

DTP run Time Error : Dump: Internal session terminated with a runtime error

Hi Experts,
I'm facing a problem during loading data from PSA to DSO from DTP. It gives Dump: "Internal session terminated with a runtime error".
When i went to PSA and see the no. of data packages, it is 1532.
Could anybody please help me how to load the data.
Thanks
Ajay

Thanks Srini!!
the load is running for 15 min and then it is throwing dump without a single package extract.
Ok...the same I'm also thinking to selective upload but can you please explain me how do i do that as it has only request in PSA.
and it is a pricing data.
Thanks
Ajay
