i downloaded jre 1.6.0 1.5.6 1`.5.7 and 1.5.6 with bean and symlinked each one one at a time and I even used the debian alternatives system and I get the same results. nowmy system points to java -version
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20060601 (prerelease) (Debian 4.1.1-1)
how do i make jin look for jre instead of libgcj if that is my problem? I hope someone out here can help me i sure can use it. As for java on my system everything works. now if I can only start this program

still points to /usr/bin/java
that is where gcj is I need it to point to jre or /etc/alternatives/
bob@Linux:~$ which java

Problem with T400 and external monitor (1920x1200 resolution)

Hi there
My laptop:
ThinkPad T400 2767-C99* (graphics is: ATI Mobility Radeon HD 3470 256MB / X4500MHD (Switchable Graphics)), OS is WinXP
I just installed the newest video driver from the lenovo page (which also installs "ATI catalyst")
Externale Monitor:
I just bought a Samsung SyncMaster 2443FW, 24" TFT monitor with maximum resolution 1920x1200
Problem:
Monitor works great with my newer T400s and my old Acer laptop. However, with my T400 (described above), I can't make the monitor use the 1920x1200 resolution. However, all the other resolutions look ugly so I need it to work with 1920x120
- If i change the resolution by rightclicking on the Windows XP desktop (and then properties=>settings) and set the screen resolution there to 1920x1200, then my monitor only used a lower resoltion (1440x900) and I get a scrolling effect as I move my pointer across the screen
- if I use ATI catalyst software to set the resolution, I can only chose smaller resolutions (it does no go up to 1920x1200)
Questions
Is that a hardware (maybe the graphic card does not support 1920x1200) or a software problem (maybe some problem with the driver) or just a matter of setting?
What can I do?
Help would be very much appreaciated!
*Original description: Based 2767-2JG: T9550(2.66GHz), 4GB RAM, 250GB 5400rpm HD, 14.1in 1440x900 LCD, 256MB ATI Radeon 3470HD, CDRW/DVDRW, Intel 802.11agn wireless, Bluetooth, Modem, 1GB Ether, UltraNav, Sec Chip, FPR, Camera, 9c Li-Ion, DOS License

Thank you for your answer.
I have already installed the newsest drivers from Lenovo. I don't really see why I should install a non-official driver. I am convinced that it must work somehow with the official driver.
Kind regards
there are plenty of instances where the official driver have glitches... just look around the forum to find instances of which.... while official drivers maybe better in most instances, there are always the odd case where it doesn't work as well as it should. If they perfectly out of box, then there would never need to be multiple revisions and updates.

Problem with web.show_document with Jinitiator and Firefox

Not sure Firefox 2.0 is officially certified with Forms 9.0.4.1 and Jinitiatorbut regardless we have some users who want to use this combination. Everything seems to work fine except for the calls to web.show_document which opens a new browser window and displays some html etc.
The problem is that even though the client Forms JVM is Jinitiator (1.3.1.18 or .21) when the call to web.show_document occurs somehow the Sun Java Plugin starts and having the two JVM's at once causes a fatal crash in Firefox. Can anyone suggest a way to preven the second JVM from opening?
When the user uses the Sun Plug as the client Forms JVM there is no problem as the second JVM does not open. Unfortunately some users insist on Jinitiator with Firefox hence the problem. -quinn

James,
This whole applet embedded in a browser model for webforms is driving us batty at times. The list of problems includes:
1) Users are constantly tempted by browser controls and accidentally do all sorts of things to get them in trouble. This has included but not limited to using the navigation arrows, jumping off to read their email in the same window as the form and returning to a dead forms session, minimizing, resizing, blurring off to another window and then returning back by clicking on the title bar of the browser and wondering why the form doesn't tab etc.
Sure hobbling the browser by opening with limited functionality is a possibility but not a complete solution.
2) New versions of browsers seem to break something. Both IE 7 and Firefox 2 have their own problems with web.show_document, especially file associations such as CSV and DBF and trying to open things in Excel in IE7.Firefox seems to have less problems for some yet some some oddities like the one that started this thread (and 2.0 opening new windows in tabs by default instead of windows).
3) JVM jigsaw puzzle. Is it Jinit or Sun, which versions? Which combinations of browser version and JVM works.
4) General fragility of the whole architecture. Running a client JVM in a web browser on top of a PC Operating system connectiong to a forms server over a network embedded in a Java Container server on a full blown web server running on a unix operating system is pushing the bubble. Throw in the mix that any of these components can be combined in numerous ways makes one wonder how it works as well as it does.
Still users randomly getting dropped connections to forms server (network gltches?). General sluggishness (poorly written forms?). Periods of users with unduplicatable errors primarily network related it would appear.
General feel that it is not rock solid stable. Perusing metalink documents on performance and tuning gives too much and too general info to troubleshoot so just shrug shoulders and say 'network problem'.
What's the solution? Java webstart would seem to help at least with the browser realted issues but is that supported and documented how to use yet. Also we'd lose web_show_document which is critical (could it be replaced by webutil calls to open browser?).

Problem with Z60m R&R

Hi,
I have a Z60m (2530-37U) and am having a lot of problems with Windows XP being very slow. I tried to create R&R disks from the Think Vantage app, but it won't launch. I then bought a new HDD and installed it, I used the BIOS to "restore to factory" settings but after hours of that, there were essentially no drivers for this model, so I had no NIC and the video drivers were VGA only.
I created R&R disks from this install and tried to restore to factory settings and again after hours of CD swapping, etc, it installed Windows XP "Home" and still had a serious deficiency of drivers.
Any thoughts on what I am doing wrong? I am just trying to get this machine back to XP Pro, factory settings.
Thanks,
--Pete

well you should reenable it from your bios.

Problems with the load of Deliveries

Hi experts,
I am having some problems with the load of Deliveries from R/3 into BW.
In LIPS table of R/3, there are 41412 records. I delete the setup tables and realize the extraction with the transaction OLI8BW. After that I launch a simulation with RSA3 but only 6765 records are taken into account.
Apart of that, there is a range of deliveries documents (between 180000000 and 1084000000) that is not be taken into account.
Has someone have similar problems with the load of deliveries?
Thanks.

Matute,
you can try comparing those missing records with those already extracted. I found in my side that some records with document category of "H"(Returns) don't be extracted by 2lis_12_vcitm.

Problems with T60p

Hello,
I've got a problem with my display. After a view seconds in runtime my display switches very dark. Looks like as it is off.
But the System is currently running. If I'm lightning the display I can see a little bit of my Desktop. What can it be ?
The Bios is flashed to v2.23 OS is Windows Vista Ultimate Display Driver is also the newest.
This problem starts by updating the Adobe Acrobat Reader 8.0.
I can go to R&R-, in Bios- or in OS Screen, its all the same. Display is going dark after a view seconds.
Is there a hardware part broken ?
Sorry for my English -.-

15.1 ?? is that 14.1 or 15 inch??
This means that the CCFL needs to be replaced you can try to do it, which costs like 20 dollars for a new CCFL tube versus 300+ dollars for a new screen.
You can check out forum.thinkpads.com regarding how people did it. I know Harryc the mod on that forum actually changed a CCFL tube on his R51 or R52 a while back, so i think you could post a message there asking for tips on how to change the CCFL.
If you don't have the time then you can buy the whole LCD and swap it out.

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){
          interrupt();
}

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.
Graeme.Hi Graeme,
I dont understand what you mean by redirection to file? some of my code below.

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) {

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)

Also when it's having this problem, the "VM Thread" is always using a lot of processor time. We did a couple of pstacks today while it was having this problem, and this thread was stuck in the ONMethodSweeper.sweep for over 15 minutes when we finally killed the server.
From the thread dump:

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.
