Problems with 6230 & Ca-53

I have some problems with connectivity:
mobile Phone: Nokia 6230
Data Cable: Original nokia CA-53
OS: Windows XP professional Service Pack 2.
PC Suite: 6.84.10.4
Once i installed the Nokia PC suite,i connected the Cable and the mobile, following the Suite's wizard, and nothing happens. neither in the computer nor in the phone. I had the mobile unblocked, and the USB ports were active.
Being readed some topics here, I tried to uninstall the nokia suite, and all of the nokia components in my laptop; and tried to install all again.
I also tried a bat found in other topic and there were no positive answer, everything staid the same.
Any idea about that?

I have a very similar situation here. Took me a while to figure out why existing user certificates are OK but no new users can enroll. I checked all certificates for expiry. No go. It was not the expiry ("Valid to") time, but rather the "Valid From" time that is messed up.
This is what happens: The rollover gets created and replaces the original one (which remains in memory, no flash) But the new one is valid from the expiry of the old one - in my case TOMORROW and after a power-outage the day before yesterday (the most definitive way to get a reboot!) I only have the new NOT YET VALID certificate.
OK, I can wait until tomorrow and see if it works. But the design is far from intelligent. The industry standard is that when you renew a certificate, the validity of the new one is immediate - even if it means it runs for a few days longer than the designated lifetime.
So much for the overlap period of 30 days (as you can see from your own post) if the old certificate goes away after a reboot and the new one is not yet valid! (The CA certificate expiration timer gets reset to some Unix time-zero ( 01:00:00 CEST Jan 1 1970) which I take to mean "not valid yet".)
I only have a few days of trouble - and just one to go after finally working it out, but it could have been up to 30 days if I for any reason had rebooted after the roll-over certificate got created.

Nokia music manager problems with Nokia 6230 model...

Hello. Recently I installed the newer version of nokia PC-Suite, the version 6.8.22. I have a nokia 6230 model HS-12 with HS-3 handsFree attached. Make the connection via Bluetooth (SMC USB Bluetooth) over a Windows XP SP2 system. The connection works fine.
The problem arrives with the new MusicManager software.
First, the playlists that this program creates, generates a error in mi phone. It says "Invalid tracklist". Surfing the web, the problem was that MusicManager generates the playlist entries (in the phone) refers to C:\ and D:\ (this for the MMC), when the phone internally works with unities A:\ and B:\. Changing "manually" the playlist it works, so if any people with design responsabilities read this, please take note.
Second, when convert my .MP3 files into .AAC files, the program converts the files into a .AAC but in MONO !! The music only sound in one channel, when the .MP3 is full stereo. Really, the conversion is in Stereo, but only converts one channel. The other remains muted. I have no idea of this problem. I listen the "mono" files in any Windows player, even at the phone.
If any people can help me, or have similar problems, or need more information please make a reply.
Thanks.

Hi
The tracklist stuff with 6230 (Ive owned a 6230 before) is a very difficult procedure, because it is not a drag and drop process from PC to phone. You have to giggle and dive onto the Audio Manager app in PC Suite where you have to find the Playlist folder in your phone memory and place all playlists there to be able to be recognized by the phone. Simple drag and drop will not work (like the m3u is in the MMC).
About your mono problem, I haven't checked out this feature of Music Manager because I still think its purely buggy even of the newer features and new face it has now. Better use other music software to transcode your MP3's such as dbpoweramp's Music Converter software (its free trial for 30 days, after that the MP3 encoding and Power Pack features are useless, if you download other codecs, you can use them after the trial.)
cheers.
The world might be a better place if you were I.

Nokia 6230 Contacts Sync Problem with Outlook

I have a Nokia 6230 and used to sync my contacts with outlook using PCSYNC. Now I receive a message that sync is completed but only 1 or 2 contacts are copied to the outlook (always the same ones). I have already updated the PC Synch version many times, tried to change configurations on PC Sync and on the phone, created new folders on outlook and sync profiles, cleaned the configuration files on "documents and settings" folder, contacted Nokia phone suport in Brazil, but nothing worked.
I use Windows 2000 SP4 in English, connect through Infrared and have the 6.81.13.0 version of PC Sync (I have already tried many other versions). I'm using Phone memory. When I use PC Sync explorer those same few contacts that are synchronized are the only ones that I can see in the contacts folder.
I think the problem is in some configuration file in Windows environment or I have a problem with the phone set.
Please if anyone could help me I would apreciate. I have lost many hours trying to fix that problem.

Today I searched through the discussions and found many other users with the same problem (Himalaya2050, Marbru, tugrulislier). Almost everybody using Nokia6230 and using international character set, maybe the root cause for the sync problem.
I think Nokia should have a tested fix for that problem.
Was the phone update the solution for other users? Do you have any feedback? I haven't found in the discussions any user with that problem solved.
When I first contact Nokia support in Brazil they told me to do many time consuming procedures (reinstall and update PC sw many times) that didn't worked and didn't make sense for me, as the sync was working with previous version. So I don't want to try another non tested solution, because I will have to go to a tech assistance, wait and probably loose all the information stored on the phone.
I think I will have to exchange my phone ...

Problem with mail for exchange after update on E72...

Hi everyone,
I updated Nokia E-mail to ver 3.9 on E72. Now I am facing a problem with mail for exchange. I have configured gmail on mail for exchange. I recieve a warning that "unable to sync contact administrator if problem persist". It started to pop up just after the update was over and is very frustrating. Even previously i used to recieve mails instantly but now it generally takes half an hour for me to recieve them. I deleted and created mail for exchange several times but to no avail.
Also i am not able to automatically recieve mails other emails which i have configured. every time I have to manually download them everytime.
Can anybody suggest a way out.
Thanks
Anil

It could be a problem if you're using your network's connections...
I was on a Pay & Go tariff with o2 some time ago, and needed secure connections for various things, o2 told me they didn't provide secure connections on Pay & Go tariffs...
Could be worth checking with them to make sure it's supported.

Problem with two of my business rule triggers

Good morning every one,
I have a small problem with two of my business rule triggers.
I have these tables:
pms_activity
csh_cash
csh_integrate_leh
csh_integrate_led
and my process goes like this:
upon approval of a row in my pms_activity table I have a trigger that insert a row in my csh_cash - and in the csh_cash table I have a trigger that will insert in the csh_ingerate_leh and csh_integrate_led.
my problem is pms_activity does generate a row in csh_cash but the trigger in the cash does not fire to generate a row in the csh_integrate_leh and led tables.
I have generated in the following order after I created my business rule:
I have generated the table from the designer (server module tab)
I have generated the CAPI from the head start utility
I have generated the API from the designer
I have generated the CAPI from the designer
I have run the recompil.sql
I have checked that my business rule trigger is enabled and should run on insert and no where restriction
=== this is my business rule logic ======
l_rule_ok boolean := true;
begin

Any help will be appreciated as I have struggled with this for two days.
Thanks

hmmm...
Try resetting it again and restoring with the same backup file...
Does the phone work properly once you've reset it before you try restoring? A lot of people here have experienced problems restoring from backups... could be worth forgetting about it and starting from scratch.
You could try contacting your nearest Nokia Service Centre (www.nokia.com/repair) and see if they can do anything - it may need the firmware reinstalling or upgrading... possibly... give them a call though and see.

Please try using the phone without a Memory Card instered. If this solves the problem then you have got a bad memory card. I have had similar problem with a Nokia 6230i with a defective MMC card.
Experience and persistence are second to none just ask user one.

Any problem with 6110 navigator?

Hi,
Does anyone has any problem with your 6110 navigator? It seems like the phone always reset on its own and hang whenever the alarm clock goes off. I have sent it back to nokia care center, they upgraded my firmware but it hang when the alarm clock goes off. The nokia care center checked it again and said that it's due to my SIM card. I am not using a 3G SIM card. Does anyone has similar problem?

An older SIM card can cause problems in newer phones. You might want to upgrade your SIM card and see if that cures the problem.

HP posted a workaround for this problem while they were working with Microsoft to get the root cause of the problem, many customers commented that the workaround helped them out and they were able to print. This workaround was not easy to use as the customer needed to add another printer manually and changed drivers.
We can now announce that the problem has been fixed, the problem involved a Microsoft Network component that HP was using to talk to and track the printers on the network. This fix is being rolled out by Microsoft via Windows Update and anyone who has Windows Update enabled and set to automatically install updates should have already received this update. For those that do not have Windows Update setup to automatically install fixes the fix is available now and should be installed.
The details of this fix and a manual method of installing it can be found here.
http://support.microsoft.com/kb/3000461
This fix is only designed for users that are using there printer on a Network (Wireless or Wired) and will not fix partial printing problems encountered with USB connections.
There are many threads in HPs forums about this issue (below are links to a few of them)

So please help me.
Solved!

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,
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) {
                    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)

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!
