Problems with JPopupMenu

Hi :
I have a problems with a JPopupMenu.
I have a JTable in a modal JDialog with some rows and I want to make some action with some rows so I make JPopupMenu visible with right click (no problem) but, when it reachs the JDialog border, it appears cut because it can't paint out of JDialog limits.
What can I do to watch the entire JPopupMenu ? It's urgent.
Thanks.
Miquel

This is because the Popupmenu is a lightweight component (which can't display beyond the borders of the window), try myPopup.setLightWeightPopupEnabled(false); that makes all popups in your app heavyweight.

Flickerring Problem With JPopUpMenu

Hello Friends,
In my application made in Java i show a JPopUpmenu on a JINternalFrame in a DekstopPane which is further kept in JFrame. The contents of the PopUpMenu may vary as according to the various places where the mouse is clicked. Sometimes when the mouse may be clicked on the lower part of the applciation some part of the PopUpmenu goes out of the visible area of the screen. For that after showing the popupmenu i get the height of the popup menu and shift it accordingly so that its length doesnt go out of the viewable area. It works fine but the problem is that it gives a little flicker. And alsoo of i try to set the position before showing the pop up menu i am not able to do so because before calling the show() method of the popUPmenu i am getting the height and width of the pop up menu. Please help me out.
Any type of pointers and links would be highly helpful.
Thanks in Advance
Vikram.

HI!
it didnt work
here is the code snippet
          popupClass.pack();
          popupClass.requestFocus();
          java.lang.System.out.println(" HEIGHTTTTT "+popupClass.getHeight());
          int Height = (int)Toolkit.getDefaultToolkit().getScreenSize().getHeight();
          int Width = (int)Toolkit.getDefaultToolkit().getScreenSize().getHeight();
          if ((DiagramInternalPane)getParent() != null)
               if(((mouseY+popupClass.getHeight()-((DiagramInternalPane)getParent()).GetParent().scrollpane.getVerticalScrollBar().getValue()+AsterixApplet.getFrame().getY()) > Height-160) && ((mouseX+popupClass.getWidth()-((DiagramInternalPane)getParent()).GetParent().scrollpane.getHorizontalScrollBar().getValue()+AsterixApplet.getFrame().getX()) > Width-20))
                    popupClass.show(comp,mouseX-popupClass.getWidth(), mouseY-popupClass.getHeight());
               else
                    if((mouseY+popupClass.getHeight()-((DiagramInternalPane)getParent()).GetParent().scrollpane.getVerticalScrollBar().getValue()+AsterixApplet.getFrame().getY()) > Height-160)
                         popupClass.show(comp,mouseX, mouseY-popupClass.getHeight());
                    if((mouseX+popupClass.getWidth()-((DiagramInternalPane)getParent()).GetParent().scrollpane.getHorizontalScrollBar().getValue()+AsterixApplet.getFrame().getX()) > Width-20)
                         popupClass.show(comp,mouseX-popupClass.getWidth(), mouseY);
          if(getParent() != null)
               getParent().repaint();
          popupClass.show(comp,mouseX, mouseY);
          java.lang.System.out.println(" HEIGHTTTTT AAAAAAAAAAAAAAAA"+popupClass.getHeight());
Before caluing the show() , method i am getting the height as 0 and only after calling the show method i am getting the actual height. Is it a java bug or something ?
Anyway thanks for all ur help

Problem with JPopupMenu and JTree

Hi,
Is there any way to have different JPopupMenu for every node.
When I right click on the treenode there is popup menu have a "*JCheckBoxMenuItem*". By default the value of that checkbox is false. Now when i try to right click on a particular node and select the checkbox the selected value gets applied to rest of all nodes also.
How can i just set the value of the checkbox to one perticular node.
my code is
import java.awt.*;
import java.awt.event.*;

import javax.swing.tree.*;
public class TreePopupMenuTest {

    JTree tree = new JTree();
    tree.setComponentPopupMenu(new TreePopupMenu());
    JPanel p = new JPanel(new BorderLayout());
    p.add(new JScrollPane(tree));
    p.setPreferredSize(new Dimension(320, 240));
    return p;
class TreePopupMenu extends JPopupMenu {
    private TreePath path;
    private JCheckBoxMenuItem compress=new JCheckBoxMenuItem("Compress");
    public TreePopupMenu() {
      super();
      add(compress);

Jpopupmenu visibility problem with JWindows

Hello,
BACKGROUND:
I am attempting to implement a feature similar to one found in the netbeans IDE for a programming editor I am helping to write. The feature is an autocomplete/function suggestion based on the current word being typed, and an api popup for the selected function.
Currently a JPopupMenu is used to provide a list of suggested functions based on the current word being typed. EG, when a user types 'array_s' a JPopupMenu pops up with array_search, array_shift, array_slice, etc.
When the user selects one of these options (using the up/down arrow keys) a JWindow (with a jscrollpane embedded in it) is made visible which displays the api page for that particular function.
PROBLEM:
The problem is that when a user scrolls down the JWindow the JPopupmenu disappears so he user cannot select another function.
I have added a ComponentListener to the JPopupMenu so that when componentHidden is called I can do checks to see if it should be visible and make visible if necessary. However, componentHidden is never called.
I have added a focuslistener to the JPopupMenu so that when it loses focus I can do the same checks/make visible if necessary. This function is never called.
I have added a popupMenuListener but this tells me when it is going to make something invisible, not actually when it's done it, so I can't call popup.setVisible(true) from popupMenuWillBecomeInvisible because at that point the menu is still visible.
Does anyone have any suggestions about how I can scroll through a scrollpane in a JWindow whilst still keeping the focus on a separate JPopupMenu in a separate frame?
Cheers

The usual way to do popup windows (such as autocomplete as you're doing) is not to create a JPopupMenu, but rather an undecorated (J)Window. Stick a JList in the popup window for the user to select their choice from. The problem with using a JPopupMenu is just what you're experiencing - they're designed to disappear when they lose focus. Using an undecorated JWindow, you can control when it appears/disappears.
See this thread for information on how to do this:
http://forum.java.sun.com/thread.jspa?threadID=5261850&messageID=10090206#10090206
It refers you to another thread describing how to create the "popup's" JWindow so that it doesn't steal input focus from the underlying text component. Then, further down, it describes how you can forward keyboard actions from the underlying text component to the JWindow's contents. This is needed, for example, so the user can keep typing when the autocomplete window is displayed, or press the up/down arrow keys to select different items in the autocomplete window.
It sounds complicated, but it really isn't. :)

Problem with file dialog (root frame)

Hi guys
I�m having a problem with open up a filedialog.
I have a rendered jlist and the are some items inside. The user, can right click any item and choose from a list some commands (print, save, update etc)
Everything works fine but when he clicks the SAVE option (again, right click and choose save)
FileDialog fd = new FileDialog(new JFrame(),"Save PAX list",FileDialog.SAVE);
I cannot use new JFrame() (as I did above) because it might block the application.
For this I�m trying to get the root by:
Component c = SwingUtilities.getRoot((Component)e.getSource());
JFrame myFrame = (JFrame)c;
And than:
FileDialog fd = new FileDialog myFrame,"Save PAX list",FileDialog.SAVE);
This get me a null frame :- (
Anyone?

The following worked on a "normal" menu item. I didn't test it on a "popup" menu item:
JMenuItem mi = (JMenuItem)e.getSource();
JPopupMenu popup = (JPopupMenu)mi.getParent();
Component c = SwingUtilities.windowForComponent(popup.getInvoker());
System.out.println(c);

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)

"VM Thread" prio=5 tid=0x000e2d20 nid=0x2 runnable

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.
