Problem with mutated vowel

Hello,
since I use Acrobat 9.0, I have a problem with the display of one mutated vowel: when I copy a text from an Acrobat-generated PDF-document and paste it into a Word document (Office 2004 and Office X) only the display of the German "ü" is not correct, when I use the "Optima" or "Arial" fonts.
With the Arial font an "u" followed by a square symbol is displayed.
With the Optima font the two points are shifted to the right side.
"ä" and "ö" and all capital letters are displayed correctly.
When I try "find/replace" in Word, the incorrect "ü" is not found.
Does anybody know a solution for this problem?
Your help and hints are appreciated.
Volker

Hey Paul and Graffiti,
thank you for your hints. The umlaute (mutated vowels - ä,ö,ü) are direct keys on a German keyboard. So it's not the problem to find the "ü" or a keystroke to insert. The problem seems to be in the step of conversion from the Acrobat and the display in a text editor after pasting.
Fonts like Baskerville, Big Caslon, Courier, Futura, Geneva, Helvetica, Lucida Grande, Palatino display the lower "ü" correctly.
Arial, Times, Times New Roman and all "TTF-fonts" don't, if I paste. When typed directly, the ü is displayed correctly.
Unfortunately, applications to regulatory health authorities require the font Times New Roman. Of course, I could correct each vowel by deleting and typing "ü" by hand, but my manuscripts are normally about 50 pages . . .

Blend in a new account with mutated vowel

I have problems to blend in a new account with mutated vowel - to write the mutated vowel with two letters is not the right solution.
So - how can I solve this problem?

Hey Lynx,
The 'you are running this application for the first time' thing is normal as most applications will put a few plist files and settings in a couple of places in your home /library folders. I wonder though about having to re-serialize...Have you installed them in other places rather than your /Applications folder? If not, some applications will ask if you want to install for all users or not- but I'd say that user speciffic applications are about 20-30% of apps...-ish ^^
Maybe running the installers and installing for allusers would save you a bit of a hassle going forward?
hope it helps

Translating with Umlaut / mutated vowel

Hi everybody,
I got the next problem in WD4J.
I've created a simple text view on my screen with the content "headline". After saving the view I have the possibility to translate the text in the navigator. The only thing I have to do is to copy the xlf file of the view and then I can edit the element in the tab resource text. This is very simple and works perfectly.
Until I don't try to translate a text that will contain in german a mutated vowel like ä ü ö. I can edit my entry but when I save the xlf nwds is processing a roll back to the old version without the mutated vowel. When I am not using an umlaut the xlf file will be saved and works perfectly.
How can I translate content with special chars like ä ü ö in the xlf file?
Thx a lot.

Hi Radhika,
I found your point under
Window > Preferences > General > Editors > Text editors > Spelling
but there the value "UTF-8" is already selected on the point encoding.
I can enter the mutated vowels in the text fields and edit the next one. That works. But when I press the save Icon it involves a roll back to the old values.
I have added a screenshot.
[Link|http://server3.uploadit.org/files/mrischah-xlf.jpg]
As you can see, the editor will accept my changes but on pressing save all changes will be reset.
Thx for help
Edit: Maybe this helps to find a solution: on the tab "header" the field "source language" is disabled and contains the creation language of the component.

Can anyone help me?

You are trying to lookup data from qw_qualifier you are currently modifying. You could see the data in a inconsistent way and Oracle is protecting you from it.
You could read here about how to program around this problem.
But: your table design seems questionable. You have two records for qw_qualifier and you are trying to log it into one qw_qualifier_log record. Maybe you could fix that, and the need for querying the same table as you are updating is removed.

Rob.

Problem with Arabic font: In certain contexts, when writing Arabic with vowel signs (fatha, damma, kasra, sukun) a sequence of sukun fatha/damma etc. would reverse automatically. Is this a known bug?

Problem with Arabic font: In certain contexts, when writing Arabic with vowel signs (fatha, damma, kasra, sukun) a sequence of sukun + fatha/damma etc. would reverse automatically. Is this a known bug?
Example: عَيْنٌ
would automatically convert to عَيُنْ
Funnily, it doesn't seem to happen here, but it does when entering text in a web interface (using Firefox, font Bayan) and when using Text Edit.
Seems to be a problem of a specific font, as e.g. Arial MS Unicode works fine. Any hints?
Thank you!

I've no idea how i can even start using arabic vowels on Microsoft Word for Apple
You can't do Arabic on MS Word for Mac. This app has never supported RTL scripts, so you need to use something else. Mellel is best, but Pages 5, TextEdit, Nisus Writer, Open/LibreOffice should work OK.
You switch between languages by using the "flag" menu at the top right of the screen or by using the keyboard shortcuts apple/command plus space. Go to system prefs/keyboard/shortcuts to make sure that is activated.
To see which key does what, you use Keyboard Viewer.

You place vowels on letters by typing the key for the vowel after the key for the letter. The vowels are on the option/alt keys, option/alt + a gives you َ

Problems with EURO currency character

Hi,
I'm trying to insert the EURO currency character (€) in a CHAR field from a Java client but after the insert in the field I find a ? turned upside down.
I'm using
- Oracle DB server 11.2.0.1.0 running with character set US7ASCII (same problem with a different Oracle server with WE8ISO8859P1 encoding) on a Linux Red Hat server
- Java client with JDBC driver 11.2.0.1.0 (ojdbc5.jar) with JDK 5 running on Windows XP: the encoding of the JVM is CP1252.
I've googled a lot but found only solutions like "... change the encoding of the DB ...": I can't change the DB encoding.
Any idea?
Thanks.

Thank you Oradba for the explanation of the COBOL program behavior: we're going to change the DB character set (export/import seems not required, we've found an Oracle Note 257722.1 "Changing WE8ISO8859P1 to WE8ISO8859P15"). I'll mark your answer as the (most) correct.
Oviwan, NLS_NCHAR_CHARACTERSET is AL16UTF16: I tried with an NCHAR field but I can't even store correctly accented vowels.
Thank you very much everyone,

Problem with switch-statement & ä, ö, ü

Hi all,
I am doing this Java online tutorial right now and have a problem with one of the exercises. Hopefully you can help me:
I have to write a program that determines the number of consonants, vowels, punctuation characters, and spaces in an input line. I found a solution, but have two questions about it:
     Im unable to calculate the amount of umlauts (ä, ö, ü). Somehow the program doesnt recognize those characters. Why?
     In general Im not very happy with this huge list of cases. How would you solve a problem like this? Is there a more convenient/elegant way?
Thanks in advance!
Write a program that determines the number of consonants, vowels, punctuation characters, and spaces in an input line.
Read in the line into a String (in the usual way). Now use the charAt() method in a loop to access the characters one by one.
Use a switch statement to increment the appropriate variables based on the current character. After processing the line, print out
the results.
import java.util.Scanner;
class Kap43A1
public static void main ( String[] args )
    String line;
    char letter;
    int total, countV=0, countC=0, countS=0, countU=0, countP=0;
    Scanner scan = new Scanner(System.in);
    System.out.println( "Please write a sentence " );
    line = scan.nextLine();
    total=line.length(); //Gesamtanzahl an Zeichen des Satzes
    for (int counter=0; counter<total; counter++)
      letter = line.charAt(counter); //ermitteln des Buchstabens an einer bestimmten Position des Satzes
      switch (letter)
        case 'A': case 'a':
        case 'E': case 'e':
        case 'I': case 'i':
        case 'O': case 'o':
        case 'U': case 'u':
          countV++;
          break;
        case 'B': case 'b': case 'C': case 'c': case 'D': case 'd': case 'F': case 'f': case 'G': case 'g': case 'H': case 'h':
        case 'J': case 'j': case 'K': case 'k': case 'L': case 'l': case 'M': case 'm': case 'N': case 'n': case 'P': case 'p':

        case 'X': case 'x': case 'Y': case 'y': case 'Z': case 'z':
          countC++;
          break;
        case ' ':
          countS++;
          break;
        case ',': case '.': case ':': case '!': case '?':
          countP++;
          break;
        case 'Ä': case 'ä': case 'Ö': case 'ö': case 'Ü': case 'ü':
          countU++;
          break;
    System.out.println( "Total amount of characters:\t" + total );
    System.out.println( "Number of consonants:\t\t" + countC );
    System.out.println( "Number of vocals:\t\t" + countV );
    System.out.println( "Number of umlauts:\t\t" + countU );
    System.out.println( "Number of spaces:\t\t" + countS );
    System.out.println( "Number of punctuation chars:\t" + countP );
}

1. Regular expressions can vastly reduce the list of cases. For example you can capture all letters from a to z or A to Z as follows [a-zA-Z]. To match a single character in a String you can then make use of the Pattern and Matcher classes, and incorporate the regular expression. e.g.
//Un-compiled code, may contain errors.
private Pattern letterPattern = Pattern.compile("[a-zA-Z]");
public int countNumberOfLettersInString(final String string) {
    int count = 0;
    Matcher letterMatcher = letterPattern.matcher(string);
    while(letterMatcher.find()) {
      count++;
    return count;
}2. As mentioned above, Sets are an excellent choice. Simply declare a static variable and instantiate it using a static initializer block. Then loop over the String to determine if the character is in the given set. e.g.
//Un-compiled code, may contain errors.
private static Set<Character> macrons = new HashSet<Character>();
static {
    macrons.add('ä');
    macrons.add('ö');
    macrons.add('ü');
public int countNumberOfMacronsInString(final String string) {
    int count = 0;
    for(char c : string.toCharArray()) {
      if(macrons.contains(c) {
        count++;
    return count;

Problem with a trigger

I have a problem with a very simple trigger:
CREATE OR REPLACE TRIGGER contratos_factuali
AFTER UPDATE OF descrip,fautori,origpeso,origdls,
montopeso,montodls,aant,aact,fifiobserva,pedsap
ON ulises.contratos
FOR EACH ROW
BEGIN
UPDATE contratos SET factuali=TO_DATE(SYSDATE,'DD/MM/YYYY HH24:MI')
WHERE ncontra=:NEW.ncontra;
COMMIT;
END;This trigger update the column 'factuali' of this table everytime any other column of this table is updated. But returns me an error:
SQL> update contratos set montodls=1 where ncontra='ODPS-086/00';
update contratos set montodls=1 where ncontra='ODPS-086/00'
ERROR at line 1:
ORA-04091: table ULISES.CONTRATOS is mutating, trigger/function may not see it
ORA-06512: at "ULISES.CONTRATOS_FACTUALI", line 2
ORA-04088: error during execution of trigger 'ULISES.CONTRATOS_FACTUALI'What's happening?

(1) You cannot use DML to update the table on which the trigger is based. Think about it: your trigger fires on UPDATE so each time fires, it updates the table and fires again. This is what is known as mutation.
What you should do is create a trigger that executes BEFORE the update and simply do
:NEW.factuali := SYSDATE;
If ncontra is not a unique column and you genuinely want all rows of the same value to have the same factuali timestamp, well, it's very difficult, indeed I don't think it can be done. You could try submitting a DBMS_JOB to do the update, passing in the factuali value as a parameter; that DBMS_JOB would have to disable the trigger before doing the update (to prevent the recursion) and then re-enable it afterwards. Which seems like a lot of work: are you sure your design is correct?
(2) You don't need the commit statement: the triggere exectutes within the commit phase of the original update.

Problems with extension of generic abstract class

Hello,
I'm having some problems with the extension of a generic abstract class. The compiler tells me I have not implemented an abstract method but I think I have. I have defined the following interface/class hierarchy:
public interface Mutator<T extends Individual<S>, S> {
     public void apply( T<S> ind );
public abstract class AbstractMutator<T extends Individual<S>, S> implements Mutator<T, S> {
     public abstract void apply( T<S> ind );
}Now I implement AbstractMutator as such:
public class BinaryMutator extends AbstractMutator<StringIndividual<Integer>, Integer> {
     public void apply( StringIndividual<Integer> ind ) { ... }
}The compiler says:
BinaryMutator.java:3: ga.BinaryMutator is not abstract and does not override abstract method apply(ga.Individual<java.lang.Integer>) in ga.AbstractMutator
Why does it say the signature of the abstract method is apply(Individual<Integer>) if I have typed the superclass as StringIndividual<Integer>?
Thanks.

Yes, but the abstract method takes an arg of type <T extends Individual>. So it takes an Individual or a subclass thereof, depending on how I parameterise the class, right? StringIndividual is a subclass of Individual. So if I specify T to be StringIndividual, doesn't the method then take an arg of type StringIndividual?

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)

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
