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,

  • Problems with HttpSessionBindingListener in WLSP10???

    does anyone have a problem using HttpSessionBindingListener in SP10? it seems that my objects are being unbound when they are not supposed to. my session has not ended/invalidated nor are the objects removed or set again.

    CT: If I could vote this down, I would. 
    This has nothing to with internet speed or website responsiveness.  I can replicate this problem on any website displaying PDF files in Safari, and my internet connection speed is very fast.  It is a problem in Safari, or involves conflicts between Safari and a plugin.
    Asking the user to adjust his/her habits to deal with a new problem that is unique to Safari and PDF files and is equipment-independent is not moving us toward a solution to the problem.
    Okay, I'm editing this because it came across rather harsh.  Let me say this:
    It happens while displaying any PDF file -- even if it's just text without complicated graphics or video. 
    It first started happening relatively recently, though I can't say for sure when. 
    It doesn't matter whether you're using a mouse or a trackpad. 
    I'm using a Macbook Pro with a core i7 processor and independent graphics controller. 
    It happens even when Safari is the only application running. 
    It does not happen using other browsers like Google Chrome and Firefox while displaying the very same files on the same websites.
    Hope all of this helpful...

  • Problem with valueUnbound() in 5.1 SP12

    We are facing a problem with WLServer 5.1 SP12 when the session gets invalidated.
    Please find the problem description below.
    References:
    1.) SessionListener Class : A class that implements HttpSessionBindingListener
    2.) Login JSP : A JSP which adds the instance of SessionListener object to the
    session once the user is authenticated succuessfully.
    Problem Description:
    Once the SessionListener object is added to the session valueBound() method is
    always called. When the user logs out explicitly valueUnbound() is always called.
    At this point we call the session.invalidate() method.
    However, valueUnbound() is not called after the Inactive interval properly, for
    instances like system crash or closing of browser by the user before he actually
    logs out. Most of the time it works perfectly, but sometimes it happens the above
    mentioned problem comes.
    I am not able to justify whether it is a problem with my code or an issue with
    the wlserver. Appreciate any help in this matter.
    I am giving the important fragments of code below for reference:
    <PRE>
    /*---SessionListener.java ----*/
    public class SessionListener implements HttpSessionBindingListener {
    private String loginUserId; //Holds the user id in the session.
         public SessionListener(String loginUserId) {
              this.loginUserId = loginUserId;
         public void valueBound(HttpSessionBindingEvent event) {
              try {
                   //Initialization code.
                   LogWriter.log(new Date() + "<BOUND>" + loginUserId + ":"+ event.getSession().getId());
              } catch(Exception e) {
                   LogWriter.log("<ERROR OCCURRED DURING BOUND>\n" + e.getMessage());
         public void valueUnbound(HttpSessionBindingEvent event) {
         //Clean up Code.
         LogWriter.log(new Date() + "<UNBOUND>" + loginUserId + ":"+ event.getSession().getId());
    Code fragment from Login.jsp
    SessionListener ssnlstnr = new SessionListener(LoginBn.getLoginId());
    session.setAttribute("ssnLstnrObj", ssnlstnr);
    </PRE>
    Thanks for any help in advance.

    Hi Simon,
    Thanks for your explanation. Yes, we are aware that the session will not be invalidated
    immediately after the system crashes or the browser is closed. We are using weblogic
    5.1 , so use weblogic.properties file instead of weblogic.xml. The property used
    is, 'weblogic.httpd.session.timeoutSecs'. Currently, it is set to 600 seconds.
    So, the session should be invalidated after 10 minutes if there is no activity
    done, even in the cases of system crash. This is inturn fires the valueUnbound()
    method. Most of the times, it is called. But, in some instances, it is
    not called. Is there any way that we can ensure that it is definitely called always,
    although the specs say that it will be called whenever the object is removed from
    the session or the session itself is invalidated.
    Thanks,
    Tejokiran.Y

    the valueUnbound method will be called when the object is removed from

    the session, if you call session.invalidate(), or if the session
    timesout (expires). the session will timeout if the user is inactive
    for
    the time specified in the session-timeout element in web.xml.
    the method will usually not be called on a system crash, and will not
    be
    called when the user closes the browser.
    the session-param InvalidationIntervalSecs in weblogic.xml does not
    specifiy the session timeout, this is an interval for weblogic to check
    for timed-out or invalidated sessions and clean up the memory.
    you can specify the session timeout in weblogic.xml with the
    session-param TimeoutSecs, but this is overridden by the session-timeout
    value in web.xml.

    I'm using jdk1.3 ..

    There is no problem with class pathIt's telling you it can't find that class. Do you think the compiler is lying to you?
    n I found HttpSessionListener class in jdk1.3 specYes, but have you seen the class file in the classpath?
    it is strange, but the error message is still rather clear IMO.

  • Problems with erradic crashes and loading of web sites and pages

    I am running os 10.5.8 and have never had internet/issues. Recently my system will not be able to load web sites or they will take 5 min or more. Or a web site will load fine but then I will not be able to load pages from this site. There are websites that this is not an issue and ones that won't load at all. Then I can go back and try the sites/pages again and they will load only to freeze again. This is true for firefox or safari. I have tried the following.Apple software update; reload web browsers; delete plist from web browser preferences; cleared all the history files; deleted all the library caches; checked the security; run dnschanger; nothing has fixed the problem.... Could this be a virus? Please help!!!!!!!!!!
    barry

    I opened more than one instance of my web application
    in Internet Explorer by pressing CTRL + N. And I
    tried to send the request from all the browsers. The
    requests are stopping my Tomcat application server.
    If I sent request from only one browser in that case
    Tomcat is sending correct response to browser to
    display in jsp pages.
    I tested this 10 times by sending requests from
    multiple browsers and all 10 times these requests
    stopped the Tomcat application server.
    Can any one please tell me where would I am going
    wrong?What do you mean by "stopped"? Did the Tomcat service shutdown?
    And also I have problems with session timeout. I
    added the following
    code to the web.xml file in my web application
         <session-config>
              <session-timeout>30</session-timeout>
         </session-config>
    My web application is automatically logging out after
    30 min if the user session is idle for 30 min.
    But I want capture the session idle time, so I can
    custom error message. Can some one please give me
    sample code to calculate user session idle time. Can
    we achieve this using HttpSessionBindingListener
    interface and HttpSessionBindingEvent class?You don't need to capture the session idle time for that. You only need to check if the session has invalidated and display a message accordingly.

  • A problem with threads

    I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
    Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
    My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
    Thank you in advance,
    Lefty

    This was one solution from the socket programming forum, have you tried this??
    public Thread MyThread extends Thread{
         boolean active = true;          
         public void run(){
              ss.setSoTimeout(90);               
              while (active){                   
                   try{                       
                        serverSocket = ss.accept();
                   catch (SocketTimeoutException ste){
                   // do nothing                   
         // interrupt thread           
         public void deactivate(){               
              active = false;
              // you gotta sleep for a time longer than the               
              // accept() timeout to make sure that timeout is finished.               
              try{
                   sleep(91);               
              }catch (InterruptedException ie){

  • Problem with Threads and a static variable

    I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
    Code functionality:
    A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
    The problem as far I understand is:
    Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
    Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
    Thanks,
    B.D.
    Code:
    private static volatile boolean bChanged = false;
    private static Thread objMainProcess;
       protected static void Init(){
            objMainProcess = new Thread() {
                public void run() {
                    while( objMainProcess == Thread.currentThread() ) {
                       GetState();
            objMainProcess.setDaemon( true );
            objMainProcess.start();
        public static void initStatusTimer(){
            if(objTimer == null)
                 objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                    public void actionPerformed( java.awt.event.ActionEvent evt){
                              SetState();
        private static void SetState(){
            if( objMainProcess == null ) return;
            synchronized( objMainProcess ) {
                bChanged = true;
                try{
                    objMainProcess.notify();
                }catch( IllegalMonitorStateException e ) {}
        private static boolean GetState() {
            if( objMainProcess == null ) return false;
            synchronized( objMainProcess ) {
                if( bChanged) {
                    SendMessage();
                    bChanged = false;
                    return true;
                try {
                    objMainProcess.wait();
                }catch( InterruptedException e ) {}
                return false;
        }

    Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
    Again as you said, There is a reason I can't call sendMessage() inside setState().
    The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
    Thanks,
    B.D.

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
    troy.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.

  • Problem with threads and camera.

    Hi everybody!
    I've a problem with taking snapshot.
    I would like to display a loading screen after it take snapshot ( sometimes i
    have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
    I was trying to use threads but i didn't succeed.
    I made this code:
    display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while((!performing.isShown()) && (backgroundCamera.isShown())){
                        Thread.yield();
                    notifyAll();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        this.wait();                   
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();This code is sometimes showing performing screen but sometimes no.
    I don't know why. In my opinion performing.isShown() method isn't working correctly.
    Does anyone have some idea how to use threads here?

    Hi,
    I've finally managed to work this fine.
    The code:
           Object o = new Object();
           display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while(!performing.isShown()){
                        Thread.yield();
                   synchronized(o) {
                      o.notify();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        synchronized(o) {
                           o.wait(1);
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();

  • Problem with threads hanging

    We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
    We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
    A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).

    String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
    We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

    Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

    Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there.  Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this. 
    We're using the following memory options:
    -ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
    -verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
    Thanks!

  • Problem with threads and ProgressMonitor

    Dear Friends:
    I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
    But I need deactivate the main class(the main class is the user interface) until the thread ends.
    I use something like this:
    LongTask myTask=new LongTask();
    myTask.start();
    myTask.join();
    Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
    What's wrong?

    Is the dialog a modal dialog? This can block other UI updates.
    In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating

  • Problem with threads and/or memory

    I'm developing an application where there are 3 threads. One of them sends a request to the other, and if the 2nd can't answer it, it sends it to the 3rd (similar to CPU -> CACHE -> MEMORY). When i run the program with 1000-10.000 requests, no problem occurs. When i run it with 300.000-1.000.000 requests, it sometimes hangs. Is this a problem with the garbage collector, or should it be related to the threads mecanism.
    (note: eache thread is in execution using a finite state machine)

    i had been running the program inside Netbeans.
    Running the jar using the command line outside
    Netbeans i have no more problems... Does Netbeans use
    it's own JVM?Depends how you set it up, but look under the options. There are settings for the compiler and jvm that it uses.

  • Installation problem with NW'04 SR1: database connection failed

    Hi all,
    while installing NW '04 SR1 on Windows Server 2003 SP1 and MS SQL Server 2000 SP4 I ran into an error related to the database connection. While performing the step "Load Java Database content" SAPinst crashes with the message
    com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
    The connection to the SLQ Server with e.g. the Query Analyzer is OK. I had a problem with this installation setup before (have a look at the corresponding <a href="https://forums.sdn.sap.com/thread.jspa?threadID=338638&tstart=0">thread</a> ), the JDBC drivers where missing on the installation master but after copying them in the right direction the installation went on with no problem up to this point...
    Has anybody an idea what could have happened here? Is this maybe a problem connected to the one I recently had
    Below I attached the sapinst.log and jload.log with more detailed messages.

  • Problem with item and/or data during page-processing-PS/SQL

    Greetings!
    On my page I have a custom report (from 2 tables) and a small form-field, that adds and edits data in the report. After generating the form with the wizard I added an extra item, to store the id from one of the tables from the report data.
    Now, on submit a calculation should take place, that updates data according user input with a procedure in Page-Prosseses:
    declare a number;
    begin
    case :PLATZ
    when 1 then a:=100;
    when 2 then a:= 50;
    else a:=25;
    end case;
    update TBL_MITGLIEDER set TURNIERPUNKTE = TURNIERPUNKTE + a
    where ID_MITGL = :P14_ID_MITGL;
    end;
    :PLATZ is user selected (1,2,3), :P14_ID_MITGL stores the reference to TBL_MITGLIEDER (and shows the change, when I select another record)
    As I understand, that process should also run, when I submit a chance, but nothing happens then.
    But when I try to save a new record (which worked without any problems before adding that process), I get this error message:
    ORA-06550: line 1, column 64: PL/SQL: ORA-00957: duplicate column name ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
         Error      Unable to process row of table TBL_TURNIERSIEGER.
    Then, when I go back into the app-builder and try to run the page again, I get this message:
    ORA-01403: no data found
         Error      Unable to fetch row.
    I am not sure, if you guys have all the information you need, to know whats going on. Maybe this has to do with session-id and the whay, items are updated. I hope you can help me.
    Thanks, best regards,
    tobi

    First can you please post all log file errors
    >> I can't really give you a solution or specific recommendation since I did not saw this error yet myself, but on your own risk you can try:
    1. You may try to just register 'dts.dll' using regsvr32.exe, but this error may indicate a bigger problem with setup.
    If you are running SQL Server 64bit then try running this at the command prompt: %windir%\syswow64\regsvr32 "%ProgramFiles(x86)%\Microsoft SQL Server\90\dts\binn\dts.dll"
    2. You can try reinstall from start (In this case you have to make sure that you un-install all)
