Problems with ClientSession.getQuery()

hi folks,
i have a problem with TopLink 10.1.3/ Oracle db 9.2.0.5.0/ oracle oci client 9.2.0.1.0/ WebSphere 5.1/ IBM java SDK 1.4.2
is there any reason why i am observing the following:
I have created a named query in the mapping workbench...
for any ClientSession cs.....
cs.executeQuery("myNamedQuery", MyClass.class) works as expected. giving me a Vector of obejcts of my target class
but...
cs.getQuery("myNamedQuery") gives me null
Using my debugger, I can see that the hashmap of queries that belongs to my ClientSession (and the owning ServerSession) are both empty. Am I missing something?
I want to set some partial object parameters on the named query before I execute it so I can't just use the executeQuery(...) call.
any help appreciated.
cheers
paul

excellent...works great. thanks!!
the only problem is that the solution uses deprecated methods.
i am seeing lots of deprecation messages in this area, but not all deprecations have replacement instructions in the javadoc.
Last time I used toplink was pre-oracle so maybe I just have 'the old way' stuck in my mind?? however.......
DatabaseQuery query = relationalDescriptor.getQueryManager().getQuery(queryName);
maybe the RelationalDescriptor.getQueryManager();
shouldn't return the deprecated DescriptorQueryManager (the one in oracle.toplink.publicinterface) but the one in the new oracle.toplink.descriptors package instead?)

XA Datasource Problem with ClientSession

Hello,
in my configuration i'm using a OracleXADatasource. When i call a sessionbean method where i only use a clientsession then i can see how toplink generates and executes the sql. But at the end of the execution i get there always an rollback.

Is this a configuration issue or it is not possible to use a clientSession?

The issue is that the OracleXADatasource you have configured in Websphere cannot be used outside a JTA transaction, or at least will cause a rollback when released.
When using a UnitOfWork you are forcing TopLink to begin a JTA transaction, so this works with the data-source.
Does the rollback cause an exception, or only the log? If it just logs the rollback, it should not cause any issue as it is just a read operation.
You must either ensure that you always have an active JTA transaction, or configure a non-JTA data-source. In TopLink you can also configure the read connection pool to use a non-JTA data-source, and have the write connection pool use a JTA data-source.
You may also want to contact Websphere on this issue as DataSource connection accessed outside a JTA transaction should be set in auto-commit mode, so should not be causing a rollback.

Problem with SLD and Creation of JCo

Hello everyone!
I have a problem with the SLD and the Creation of JCo on the Portal, in trying to create the JCo always tells me that the name used there in the SLD, being that the facility is new.
Who performs the installation, set in the SLD the ECC 6 PRD, delete it to see if I could create a JCo but still the error again when creating the ECC 6 PRD in the SLD I said that already exists and can not create it.
I found a forum which recommended re-import the cimsap .... .... zip and zip CR_Content which would clean everything, I managed to import the zip cimsap ... but in trying to raise CR_Content gives me the following message "All incremental updates of the selected aggregate import for export SAP_CR line have already been loaded before. You require a newer import to update your current content SAP_CR version 4.11." .
I recommend, do the installation again, reload the cimsap.zip and CR_Content.zip a copy homogeneous.
from already thank you very much

Hello!!
The "SLD" with which I am working up to Portal, the "ECC" installs itself as "ABAP.
Who did the installation and initial configuration, do not leave any documentation about it.
Now I need to create the systems and "JCo" necessary to enable them to implement the "ESS", but errors are presented above.
Some days ago I managed to update the CR_Content, which allowed me to create the "JCo" but at the time of the test, says' com.sap.mw.jco.JCO $ Exception: (103) RFC_ERROR_LOGON_FAILURE "name or password incorrect .
I managed to also create the portal systems, "System Administration -> System Configuration -> Content Portal" and to test it fails on "Test Connection with Connector", which as noted is associated with the connectors "JCo".
For the creation of the system, I think I should create something in the Visual Administrator ", but within the documentation that I do not see anything about it.
thanks for your help!

Weird problem with role assignment in Portal

Hi,
In our newly installed Portal for eRecruitment Production System we encounter a weird problem with assigning roles to users.
When I open User Administration and search for roles, it displays the Portal roles perfectly.
However, when I search for a user in User Administration and click on it when found, I am unable to find any roles to assign! So I am unable to find any roles, when I want to modify the assigned roles for a particular user, while the roles do exist and can be found on its own. How is this possible? Am I missing something here?
We have installed SPS 15 and use ABAP as user store. We have used reverse proxy and web dispatchers in this case.
Thanks in advance and best regards,
Jan Laros

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) {
                    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.

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)

Hi,
Here is my /var/log/messages.log output.
Since several days my computer repeatedly restarts programs that require at least a bit memory, such as firefox ('segmentation fault'), skype, virtualbox, generaly gnome 3 environment. Sometimes it happens that the system hangs and I can't do nothing, although I can hear that hard disk is working - at that moment only hard reset helps.
I know that the Dell Inspiron laptops (1720) have problems with Nvidia 8600M GT (the cold solder). Is it like that this time? Or maybe something wrong with the memory, CPU (Core Duo) cache memory?
I will be happy to add any additional information.
Regards,
Lukasz
