XI 3.1 with HP Neoview 2.4
Hello:
I'm at a client using XI 3.1 Fp 1.3 on HP64 connecting to HP Neoview 2.4.
They would like to know with the ODBC drivers that we support HP ODBC 2.3.1...and 2.3.2...
which Driver Manager is provided with XI 3.1 FP 1.3?
On my workstation using the Designer and HP ODBC Driver for windows, I can see this in the unvierse connection
ODBC manager version 03.52.1132.0000
and ODBC manager API level 03.52.0000
how the boe server running XI 3.1 FP 1.3 on HP64,
which Driver manager do we provide out of the box?
Thanks,
Hi Dwayne,
HP Neoview ODBC driver 2.3.1 data connector is already supported for HP Neoview 2.4 for XI 3.1 SP2 on HP-UX (IA-64) platform.
Please refer to page 7 of the [Supported Platforms document|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/30320fb6-155f-2c10-37bb-d9ad00a1ea77&overridelayout=true]
Hope this helps.

The attached is the trace from the UnixOdbc driver manager. Not sure, whether the difference in driver manager is the issue (ignore the error at the end, it is expected). For some reasons (or UnixODBC driver manager?!), DG4ODBC proceeds beyond the INVALID sql type error!
Your help is really appreciated. Thanks!

WIS 10008 Error in WebI from Neoview data source
Hello:
I'm getting a timeout error (WIH 00013), in Infoview,
but the webi trace logs reports WIS 10008.
The data source is neoview.
What do I do in order to resovle this error.
I've scaled webi report servers up to 2GB memory.
I have adjusted all applications with a timeout to now = 120.
Tomcat timeout = 120
I also reviewed the document on CMC & Infoview session management.
Environment details:
XI 3.1 SP2
SAP IK 3.1 SP2
HPUX-IA64
Datasource = Neoview 2.4.
Thanks,
Dwayne Thomas
P.S.
Error message from webi logs;

Edited by: Dwayne Thomas on Sep 29, 2009 7:27 AMHi,
I'm seeing similar issues. Can you please provide greater detail on the exact changes you made? I see a couple areas under the Webi Processing Servers to adjust memory. I'd also like to know where/how you adjusted your Tomcat timeout. I'm familiar with the timeouts in the web.xml files, but not Tomcat itself.
Thanks -
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,
LeftyThis 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();

Understanding problem with threads
Hi,
yesterday (at least i think it was yesterday) I posted a question in this forum, I needed help with writing a multithreaded server. The answer was simple and I wrote my program. It kinda works, but there is one thing I don't understand:
I have a class, which handles the clientconnections and one that listens for incoming conections. I pass the socket returned by ServerSocket.accept() to the clientconnection object.
There is only ONE clientconnection-object. The listener just passes the socket and calls the start() method of the clientconnection object.
The clientconnection just writes some text to the client. Connecting more than one client at the same time works too. Everything works fine. And that's what I don't get. If I have only O N E clientconnection the texttransfer shouldn't work after i connect the second client, right?
But it does, is there a mistake in my logic or am I losing my sanity? :)Hi again Danbas,
Maybe you are losing your sanity... but that's ok. :)
public void startlistening(){
while(true){
try{
clientconn cc = new clientconn(ssock.accept());
}catch(IOException ie){}
//The Constructor in clientconn would look like this:
public clientconn(Socket sock){
//No idea what to do here
Every time you perform "new", you create a new object. And you are calling new every time you accept a new socket connection. So you are creating a new clientconn object each time. -
Hi all,
I would like to ask you for a help. I need to write a small program at my university. I started to write a midlet which function would be to countdown time for sports activities. I woul like to start a new thread - the one that counts down - and at the same time make the main thread sleep. After the "countdown" thread finishes, the main thread wakes up and waits for user input. The problem is that when the "countdown" thread finishes his work, I've got Uncaught exception java/lang/NullPointerException. error and the midlet halts.

Your Licznik class has a member m of type monitor, which has not been instantiated (in other words is null) hence, when calling m.put() you get NullPointerException. Please also mind, that using Thread.sleep(1000) is not an accurate way of measuring time.
If I may, please use recommended for Java class naming conventions - some of your names use lower case, while other don't which is confusing to the reader.

Problem with threads within applet
Hello,
I got an applet, inside this applet I have a singleton, inside this singleton I have a thread.
this thread is running in endless loop.
he is doing something and go to sleep on and on.
the problem is,
when I refresh my IE6 browser I see more than 1 thread.
for debug matter, I did the following things:
inside the thread, sysout every time he goes to sleep.
sysout in the singleton constructor.
sysout in the singleton destructor.
the output goes like this:
when refresh the page, the singleton constructor loading but not every refresh, sometimes I see the constructor output and sometimes I dont.
The thread inside the singleton is giving me the same output, sometime I see more than one thread at a time and sometimes I dont.
The destructor never works (no output there).
I don't understand what is going on.
someone can please shed some light?
thanks.
btw. I am working with JRE 1.1
this is very old and big applet and I can't convert it to something new.Ooops. sorry!
I did.

public void stop() {

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,

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.
The code works fine under a console, code is supposed to exit when the client (the other server )disconnects. the problem is that but the clientworker side of the code still works. which under console it doesnt.

boolean serverAlive = true;
* Server constructor generates a server
* Socket and then starts a client threads.
* @param aPort socket port of local machine.
public Server(int aPort, String aClientName, int aClientPort){
port = aPort;
clientName = aClientName;
clientPort = aClientPort;
try{
// create a new thread
aServerSocket = new ServerSocket(port) ;
// connect to the nPortExpress
aClientListener = new ClientListener(InetAddress.getByName(clientName), clientPort, queue,this);
// aClientListener.setDaemon(true);
aClientListener.start();
// start a dianostic port
DiagnosticsServer aDiagnosticsServer = new DiagnosticsServer(port,queue,aClientListener);
// System.out.println("Server is running on port " + port + "...");
// System.out.println("Connect to nPort");
catch(Exception e)
// System.out.println("ERROR: Server port " + port + " not available");
JOptionPane.showMessageDialog(null, (e.toString()),"ERROR: Server port " + port + " not available", JOptionPane.ERROR_MESSAGE);
serverAlive = false;
System.exit(1);
while(serverAlive&&aClientListener.hostSocket.isConnected()){
try{
// connect the client
Socket aClient = aServerSocket.accept();
//System.out.println("open client connection");
//System.out.println("client local: "+ aClient.getLocalAddress().toString());
// System.out.println("client localport: "+ aClient.getLocalPort());

Problem with Threads and "plase wait..."-Window
Hi everyone,
I have a problem that I'm not able to solve in any way... I have a time-consuming task (a file decryption) which I execute in a separate thread; I've used the SwingWorker class, like suggested by sun-tutorial, and it works right. The problem is that I have to wait that the decryption have finished before continuing with program-execution. Therefore I would like to display a "please wait"-window while the task runs. I've tryed all the possible ways I know but the problem is always the same: the waitWindow is displayed empty, the bounds are painted but the contents no; it's only painted when the decrypt-task has finished. Please help me, I have no more resources....
decrypt-file code:
public class DecryptFile {
private String cryptedFileNameAndPath;
private ByteArrayInputStream resultStream = null;
// need for progress
private int lengthOfTask;
private int current = -1;
private String statMessage;
public DecryptFile(String encZipFileNameAndPath) {
cryptedFileNameAndPath = encZipFileNameAndPath;
//Compute length of task...
// 0 for indeterminate
lengthOfTask = 0;
public ByteArrayInputStream getDecryptedInputStream() {
return this.resultStream;
* Called from ProgressBarDemo to start the task.
public void go() {
current = -1;
final SwingWorker worker = new SwingWorker() {
public Object construct() {
return new ActualTask();
worker.start();
* Called from ProgressBarDemo to find out how much work needs
* to be done.
public int getLengthOfTask() {
return lengthOfTask;
* Called from ProgressBarDemo to find out how much has been done.
public int getCurrent() {
return current;
public void stop() {
current = lengthOfTask;
* Called from ProgressBarDemo to find out if the task has completed.
public boolean done() {
if (current >= lengthOfTask)
return true;
else
return false;
public String getMessage() {
return statMessage;
* The actual long running task. This runs in a SwingWorker thread.
class ActualTask {
ActualTask () {
current = -1;
statMessage = "";
resultStream = AIUtil.getInputStreamFromEncZip(cryptedFileNameAndPath); //here the decryption happens
current = 0;
statMessage = "";
}The code that calls decryption and displays waitWindow
final WaitSplash wS = new WaitSplash("Please wait...");
final DecryptFile cryptedTemplate = new DecryptFile (this.templateFile);
cryptedTemplate.go();
while (! cryptedTemplate.done()) {
try {
wait();
} catch (Exception e) { }
this.templateInputStream = cryptedTemplate.getDecryptedInputStream();
wS.close();Thanks, thanks, thanks in advance!
EdoardoMaybe you can try setting the priority of the long-running thread to be lower? so that the UI will be more responsive...

//i've tried placing Thread.sleep between these lines
g.drawLine(x, y, a, b);
//Thread.sleep here
g.drawRect(x, y, 50, 70);
}I also need to put delays between method calls but I need to synchronize them. Am I doing it all wrong? The application pauses or sleeps but afterwards, it still drew everything all at once.

im using jdk 1.6 with java wtk 2.1
ya i know..
2.1 is a jdk1.4 source
but im using souce as 1.4 during compiliation so thats not the prob
this is my code
package org.learn;
import javax.microedition.midlet.MIDlet;
import javax.microedition.lcdui.Alert;
import javax.microedition.lcdui.Display;
public class thtest extends MIDlet
Thread t;
public void startApp()
Alert a=new Alert("hello");
a.setString("hello");
Alert b=new Alert("world");
b.setString("world");
Display d = Display.getDisplay(this );
d.setCurrent(a);
t=Thread.currentThread();
try{
t.sleep(10000);
catch (Exception e){}
d.setCurrent(b);
public void pauseApp()
public void destroyApp(boolean unconditional)
its just supposed to pause between the alerts using threads
however when i run it using the wtk, the emulator run properly but when i launch the app, it stops executing giving me this:
"Error verifying method org/learn/thtest startApp()V

please can someone help me out with this, is it an error on my part or do i have to set some option.Hi gandalf123,
First, Thread.sleep is a static method, so you don't need to create a Thread object to use it.
I think the problem is due to the fact you don't preverify your midlet.
More over, you don't need to double post your question. -
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(); -
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
Maybe you are looking for
