Creator Freeze Often -- SWING Worker thread also
I'm developping an app with creator. And I have many freezes in several minutes long as some people mentioned before.
I'm running win XP on an opeteron 244(1.8G) x2 , with 2G memory. I've updated creator to the latest updates, but it doesn't seem to be better.
The things I found is that when I edit Session Bean , Creator takes especially long time to come up.
At that time, SWING worker thread of Creator IDE also stopping, No update of display , I only look window frame.
You know the SWING has a Single thread model ,so if some logic uses SWING worker's thread long time, all displying process will be stopped.
Below is the stacktrace just after a few seconds when Creator freeze by editing Session Bean.
I use the stacktrace tool at http://tmitevski.users.mcs2.netarray.com/trace.do

Since swing is not thread safe the table is updated in a swing worker thread. This should ensure that all gui updates are scheduled in the main event dispatching thread. Following is that code :-
SwingWorker sw = new SwingWorker() {
public Object construct()
try{
_myTable.updateUI();
return null;
}catch(Exception e){
return null;
public void finished(){
sw.start();
Inspite of doing these i am getting these exceptions.try using javax.swing.SwingUtilities.invokeLater(Runnable doRun)

Worker Thread and Helper Thread for Gauge updates
Hi
I know that in the Smart Ticket sample application there is an example with the implematation of "Each worker thread also has a helper thread that displays an animated gauge to indicate the progress of the worker thread".
But i can't find the sample on java.sun.com anymore..:-(. Do you have the source code of smart ticket or even an example of the helper thread implemetation. The worker thread i have already implementated.
Thanx
MichaelHere's a simple outline of what I do. This has been drastically stipped down from my actual code as I use teh message for all kinds of things incluing requests on a queue to the worker and resposes back. So in the real code I also have a success flag, a command type, an argument object and a result object with get and set methods for all of them.
1) define an interface that the GUI code can implement and pass a reference to the worker which stores it in myTarget.
interface MessageTarget
void postMessage(Message m);
void runMessage(Message m);
}2) define a message class
class Message implements Runnable
Object data;
MessageTarget target;
Message(MessageTarget target, Object data)
this.target = target;
this.data = data;
public void run(){target.runMessage(this);}
public Object getData(){return data;}
public void postMessage(){target.postMessage(this);}
}3) implement the MessageTarget interface in the GUI
// put a response from the database onto the swing queue
public void postMessage(Message r)
javax.swing.SwingUtilities.invokeLater((Runnable)r);
// process messages
public void runMessage(Message m)
Object data = m.getData();
}4) post messages back from the worker
new Message(myTarget,myData).post(); -
My X6 freezes often and it works by itself
Hi,
Someone plz help me.
I have bought X6 couple of days back and face lot and lot of issues with it.
1. It often freezes.
2. Whenever I unlock the keypad (or Phone), Facebook opens automatically.
3. Few application automatically opens by themselves, when I hold the mobile on both ends.
4. Touch secitivity is more worse.
5. I was trying to download "Twitter" Software, which took around 30 mins at last mobile freezes.
Have I chosen a wrong mobile...
Is there any solution for the above issues? Plz help me guys..
Thanks in Advance.Please consider updating your firmware.

Firefox crashes when loading Gmail, and random other pages, and freezes often.
Firefox upgraded itself to 3.6.10 sometime last Friday, I believe, and every since I cannot get into gmail, and it freezes often. When I try to log into gmail it will crash immediately. Sometimes if I click "sign in" rather than hitting "enter" it will load, but will lock up or crash within minutes or seconds. It also will lock up if I have more than three or four tabs open, often when loading a video, and crashed while loading Nexis, which I use often for work to do research.
I have disabled add-ons, disabled extensions, run in safe mode, uninstalled and reinstalled, rebooted, downgraded, re-upgraded. Nothing has worked.Problem does not seem to occur on a modern Win XP nebook with 1 gig RAM, but does on a relatively old laptop running Win 2000 with 98.5 MB ram.
Error message states that a script is running from a Firefox directory and asks to stop it. Crash occurs anyway! -
Cursor is freezing often after installing leopard
I don't know if this is just a coincidence or not but my cursor freezes often since I installed leopard on Friday. How can I solve that? So far I have been turning off the computer then turning it on to make it work. Help
Mine too. New Macbook Pro, upgraded to Leopard and started then. Continued after 10.5.1. I ONLY use the track pad. And it's only after sleeping and waking. Independent of what is running (including no apps) and processor is not being worked at all. Only cure is reboot....
I also get slowish shutdown, and once or twice a half wakeup from sleep - drives get power, but no screen.
Wondering how many who have these problems are running eyetv, or Awaken - something with wakeup style agents in the background? -
Worker Threads: Created by model or by controller?
Sometimes models needs to access blocking devices, like network cards, databases, files, and so on. This should be done by worker threads or services. But who is in charge of that? The controller or the model itself? I tend to say it is the model, as only the model knows about the fact that it accesses a blocking object. On the other hand, it is said that a model should be a POJO, so it would be the controller's job.
Is there a best practice or general design rule?It's impossible to make a general recommendations, but I'd say in many cases the answer to this question is really that the worker threads are created by neither a model or controller. Threads often need to be associated with processes and tasks which is independent of models and controllers. Instead you can use dependency injection to inject references into controllers to a common object instances which control isolated threading logic and implementation and encapsulate it to server a given responsibility (such as blocking server communication), with the entity providing this functionality also providing event driven callbacks to the models and controllers, so that they can get notified of changes for tasks spawned based upon their requests. For example, if you look at the Java JEE model, entity classes and controllers in that model usually never explicitly create or reference threads (that portion of JEE really a pretty general programming mechanism and is also applicable to client code in JavaFX).
MVC isn't a panacea solution to everything. In fact it tends to be overly quoted and widely misunderstood and what it actually is is open to different interpretation by different readers. There is a great discussion of MVC by Martin Fowler. Everybody claims to do MVC, and they are all doing it, they are just doing it in a different way, which is fine, but it means that it is not a very good reference in trying to communicate solutions to issues such as architecting a multi-threaded application.
What I would recommend instead of analyzing your entire application from an MVC viewpoint, is to use CRC modeling on it (class/responsibilities/collaborations), you can google it to see how it works if you don't already know. That way you are thinking about how to architect and build a solution to your application domain issues rather than trying to shoehorn solutions into a certain framework. Sure MVC is a great thing and is appropriate for many things, just make sure you really want to think from that viewpoint for a particular piece of the solution you are building.
With threading, you generally want to write as little concurrent code as possible. You also want this code compartmentalized, so you only need to study the concurrent code in one place (hopefully a single class or at most a single package). You also don't want the knowledge and use of the threads to leak. For example, ensure that almost all the code you write is only accessing a single thread so that you don't have to worry about concurrency related bugs and reasoning about concurrency in most of your code. This is the way the JavaFX system works. It has multiple threads internally for application processing and rendering, but from a user point of view, all the user application code just runs on a single JavaFX application thread. This makes the user code less error prone and easier to reason about and also simplifies the library API and usage greatly.
So let's say you have a server communication API which makes use of a multithreaded client pool of server connections such as apache HTTP components. Create a single class, e.g. Communicator with methods ResponseMessage send(Location destination, RequestMessage requestMessage) and void sendAsync(Location destination, RequestMessage requestMessage, Callback<ResponseMessage,Void> callback). The async version, can make use of Platform.runLater, to ensure your callback is invoked on the JavaFX application thread - then your calling JavaFX application code never needs to worry about the internal threading implementation of the communicator, it just reacts to an event driven callback (the same way something like the snapshot API works). If you need more fine grained feedback and control over the async task from your application, than rather than having a simple callback, you can return a Worker/Task which can be monitored for progress within your JavaFX application, see for instance the LoadWorker in WebEngine. If your communication implementation is actually reasonably involved and can't be implemented in a single class, that is OK, just make Communicator a facade and use multiple classes in the internal communicator package implementation, but don't use any of that implementation outside of the communicator package. You can use a dependency injection framework such as afterburner to inject a reference to a communicator into your FXML controllers. -
My iPad 2 is freezing often.
Please tell me that it has NEVER been jailbroke. If that's the case, here are some standard repair procedures:
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, if you have IOS-7, read this. -

We're using ASP.net with .Net 4, developing with Visual Studio 2012. We use SSRS 2012sp1 with local reports, so exporting the report ourselves instead of using a reportviewer control (and not using the SQL Reporting service). The reports are
executing fine when we export the report in the main thread, but if we spawn a worker thread and run a report there we receive the following error when calling Render():
Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Failed to load expression host assembly. Details: Invalid token for impersonation - it cannot be duplicated.
We only receive this when running a report that uses expressions on a separate thread. I've tried running the application pool under all the default built-in accounts (NetworkService, etc), and under admin user accounts to no avail.
This didn't occur with the previous version of our application which used .net 3.5.As mentioned, we are not using the Reportviewer control, we are rendering locally. Not certain if that would make a difference.
Also, I had tried using all the built-in accounts. Just for kicks I changed it to LocalSystem again, then reset IIS (see image below). I then tried to export the report in a worker thread and received the same error.
Here is the text from the exception:

Calling a delegate on the UI thread from a work thread inside a child class.
Hi All,
I've run into a snag developing a WPF multithreaded app where I need to call a method on the UI thread from my work thread, where the work thread is running a different class.
Currently I am trying to use a delegate and an event in the 2nd class to call a method in the 1st class on the UI thread. This so far is not working as because the 2nd class is running in its own thread, it causes a runtime error when attempting to call
the event.
I've seen lots of solutions referring to using the dispatcher to solve this by invoking the code, however my work thread is running a different class than my UI thread, so it seems the dispatcher is not available?
Below is as simplified an example as I can make of what I am trying to achieve. Currently the below code results in a "The calling thread cannot access this object because a different thread owns it." exception at runtime.
The XAML side of this just produces a button connected to startThread2_Click() and a label which is then intended to be updated by the 2nd thread calling the updateLabelThreaded() function in the first thread when the button is clicked.

runInParentEvent();
I'm unfortunately not very experienced with c# so I may well be going the complete wrong way about what I'm trying to do. In the larger application I am writing, fundamentally I just need to be able to call a codeblock in the UI thread when I'm in a different
class on another thread (I am updating many different items on the UI thread when the work thread has performed certain steps, so ideally I want to keep as much UI code as possible out of the work thread. The work threads logic is also rather complicated as
I am working with both a webAPI and a MySQL server, so keeping it all in its own class would be ideal)
If a more thorough explanation of what I am trying to achieve would help please let me know.
Any help with either solving the above problem, or suggestions for alternative ways I could get the class in the UI thread to do something when prompted by the 2nd class in the 2nd thread would be appreciated.
Thanks :)If I follow the explanation, I think you can use MVVM Light messenger.
You can install it using NuGet.
Search on mvvm light libraries only.
You right click solution in solution explorer and choose manage nugget...
So long as you're not accessing ui stuff on these other threads.
using GalaSoft.MvvmLight.Messaging;
namespace wpf_Tester
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
public MainWindow()
InitializeComponent();
Messenger.Default.Register<String>(this, (action) => ReceiveString(action));
private void ReceiveString(string msg)
MessageBox.Show(msg);
Dispatcher.BeginInvoke((Action)delegate()
tb.Text = msg;
private void Button_Click(object sender, RoutedEventArgs e)
Task.Factory.StartNew(() => {
Messenger.Default.Send<String>("Hello World");
What the above does is start up a new thread - that startnew does that.
It sends of message of type string which the main window has subscribed to....it gets that and puts up a message box.
The message is sent from the window to the window in that but this will work across any classes in a solution.
Note that the receive acts on whichever thread the message is sent from.
I would usually be altering properties of a viewmodel with such code which have no thread affinity.
If you're then going to directly access properties of ui elements then you need to use Dispatcher.BeginInvoke to get back to the UI thread.
I do that with an anonymous action in that bit of code but you can call a method or whatever instead if your logic is more complicated or you need it to be re-usable.

What is the max. count of internal worker-threads in B1iSN 88?
Hi Experts,
We have an installation of B1iSN 88 with an ECC 6.0 and 54 SAP Business One installation. The Hardware is 8 Core multi-threads processor. 32GB Memory. Now we have a problem with the queuing of Events. What we have found is that the configuration of the internal worker-threads is set to -1(please see below for the settings). We change the settings to xcl.threads=20 and it improves the queuing. My question is what is the max. count of internal worker-threads per core? so that we can know how many worker will set and if we need to upgrade the CPU to 16 Core..
# The max. count of internal worker-threads afforded for the internal Scheduler (defaults to 1)
# The value of 0 means that there is no limit (what in general should not be set up).
# A negative value means the count of threads per available processor
xcl.threads=-1
Regards,
WilsonYou're very welcome.
Yes, they are very nice machines.
What a jump in performance when I swapped out the Pentium 4 620 mine had, for the PD 945, and tossed in 4 GB of memory.
That box will also run the Radeon HD 6570 with no problem too, which is what I put in mine.
The downside of that model is that there are no settings for ahci or raid.
I own or have owned every CMT since the d510 with the exception of the dc7900.
My main PC is now the 8200 Elite CMT which I installed W8.1 on.
It has an i7-2600 processor and 32 GB of memory, 1 TB SATA III hard drive.
I threw in a Radeon HD 6670 in that one.
Best Regards,

After installing yosemite on my laptop, once I open the internet through Safari, it at times will freeze or discontinue working causing me to close the wifi and turn it back on then reload the internet page to get it to work again. Is there any way to fix this?
1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
Part 1 of 8 done at … sec
Part 8 of 8 done at … sec
The test results are on the Clipboard.
Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

Mac OS X Lion freezes often in help related activities
Hello, Mac OS X Lion 10.7.3 freezes often on my 13-inch, Mid 2009 MacBook Pro. It seems it's (almost) always related to some activities with help system - it mostly happens when I use search input field in Help menu of any application or sometimes if system help viewer is opened.
The freeze is little bit strange. Typical symptoms are
mouse doesn't freeze, but cursor changes to spinning wheel when it's placed over application which caused freeze
frozen application doesn't respond to any input
it's possible to switch to another application with mouse or keyboard shortcut
any other application appears to be working correctly (mouse cursor is not spinning wheel at least), but UI interactions (with mouse or keyboard) get it to the same state as described above
applications can't be forced to quit, even with keyboard shortcut
finally, all applications and OS X freezes, mouse cursor still moves (even using Magic mouse), but nothing works anymore. Only solution is to switch MacBook off and on
I tried to delete Caches/* in /Library and ~/Library, but it didn't help. My MacBook is upgraded to 8 GB RAM with Kingston DDR3 modules (choosed via Kingston compatibility tool) and Kingston SSDNow V200 Series 256GB SSD disk (trim enabled with Trim Enabler). Crashes are probably not related to RAM upgrade, but it may relate with SSD installation (but I'm not sure when they appeared first).
Freezes almost don't happen in other situations than described.
Any ideas what could cause these problems? Thank you.I am having similar problem with my machine, a Mac Pro (1,1) with Kingston V200 256GB SSD installed. It is fairly random when it chooses to freeze up, and you described it exactly-- I can still move the mouse and select programs, but nothing is happening, requiring me to do a hard reboot. I have noticed the past few instances it seems the trigger might have been an unattended alert box from Apple Mail (asking for a password) which I didn't see until getting home from work, so it could have been sitting there for hours. Not addressing the alert box holds up all the other Mail processes and I guess it just snowballs (?)
Anyways, I'm thinking the problem is this particular Kingston SSD (the V200). I have another Kingston SSD (the SSDNow V Series SNV425-S2/128GB) which I was using as the boot drive and it has worked flawlessly since I installed it. Later, I got a good deal on the V200 and decided to use it as a secondary drive to hold my working data, for things such as my huge iPhoto library file. Not long after installing the V200 I noticed the problems starting, and after a lot of troubleshooting I noticed this pattern with iPhoto:
If I had just booted up and was using the computer actively and then launched iPhoto, everything was fine. If the computer went idle for a while and then I launched iPhoto, I would get an error about it not being able to write to the iPhoto library (remember the library was housed on the V200). After many trial and errors I found that the solution to this was to use Disk Utility and unmount the V200 (sometimes having to force eject it), then remount it, and then I could run iPhoto fine.
And then of course there were times when I was just trying to browse the V200 in the Finder and it would cause the system freeze as described above. It seems like the drive somehow goes to sleep and then you just can't get it to wake up and it causes all sorts of problem. Whenever I have to hard reboot I run FSCK in single user mode, and I've been getting this error notice a lot:
AppleAHCIDiskQueueManager::setPowerState(0x1c7b1600, 1 ->2) timed out after 100892 ms
SATA WARNING: Enable auto-activate failed.
However, it will finish the disk check and say the disk is OK, with that "File System was Modified" note. Then when I run the check again it goes through with no problems.
I ended up doing a warranty exchange with Kingston and got a new replacement drive (as opposed to them refurbishing the drive I sent in). I am now using the new V200 as the boot drive, which is turning out to be a bad idea, but I kind of wanted to test it out.
I read on this forum that it might have been my Icy Dock adapter case, which is used to fit the SSD into the Mac Pro hard drive sled, perhaps a faulty case causing the problems. But when I installed the replacement drive I nixed the Icy Dock and have it directly connected, and the problems still remain. I had used TRIM enabler at one point but turned it off long ago to troubleshoot, so I don't think that affects this problem.
Incidently, while I was waiting for Kingston to send back the replacement V200, I was using an external firewire drive in its place as a secondary data drive (ie. the drive housing my iPhoto library) and never had any problems or freezes.
So that's my woes. I can't pinpoint it exactly or definitively but the evidence I have points to something screwy with this particular Kingston SSD model. I am going to contact them again and see about returning it for a refund. If anyone has any helpful information or insight I'd appreciate the info. -
How to destroy the worker thread
My problem is I have a swing client which has 2 buttons, search and cancel. In search button I am creating a new worker thread which will be calling my EJBs method. Thus I have an event thread and a worker thread running. Now when I click cancel button I want to interrupt my worker thread and screen should enable the search button but what happens is when I click cancel button it still continues with the worker thread even though I am calling workerthread.interrupt() method and this results in showing the result of the EJB's method on the screen. how can I prevent the worker thread to stop executing the ejb's method and come back to normal mode.
This application its a socket server, Im doing:
main {
Thread1 - createServer();
Thread2 - createLogging();
waitForServerShutDown();
the createServer method must be placed in a thread, its must not blocks the application because createLogging(); must be executed just after the server was created and createLogging(); doesnt blocks the application then... I must block the main{} to keeps application running
