Restarting a Thread

Hi.
I'm in the process of doing some research and I'm basically creating a web crawler that starts cralwling from the page that being viewed by the user. This works fine but what I need is for the crawler which is basically some Threads to restart crawling the web from the new page that the user is viewing.
For example:-
What i want is....
User Starts viewing www.google.com.
Crawler looks at googles links and follows them.
User then views www.java.sun.com.
Crawler looks at java links and starts to follow them.
What is happening at the moment is...
User Starts viewing www.google.com.
Crawler looks at googles links and follows them.
User then views www.java.sun.com.
My problem is crawler is still looking at and following googles links.
I would realy appriciate any help or advice.

Without seeing what you have I'd suggest setting the crawling threads to null and making new threads. This means that if you aren't already doing it you will have to store the threads in a variable so you can access it any time. If you want more help from people try posting some code.

Starting, returning data from, ending and restarting a thread

I have a program that uses SWTCalender and threads. When I click a button (date), the event will cause a thread to be created, which will create a new shell that contains the calender. When I click on a date in the calender, I want the calender to pass the date back to the other shell at the same time. BUT, I also want it so when I close the calender thread, I can reopen it, as, when I try and reopen it at the moment, I get this error:

You cannot 'restart' a thread; read the API documentation; you have to use a fresh new Thread object for that.

Java.lang.IllegalThreadStateException - Trying to restart a Thread

Hi, since I'm new to this forum, I'll start right off with a question.
I'm trying to create an application, which guides the user trough several windows. In the first window there is some user input, and frame2 opens. frame2 then opens, depending on user input, frame1 (restart the cycle) or frame3.
I tried this with Threads, a Thread for each frame to keep things less complicated (less messy etc.).
Now the problem:
When I try to restart frame1, I get the error "java.lang.IllegalThreadStateException". The source code:
public class Sss extends Thread
    (public variables that can be changed or used by other classes)
    public static frame1 a = new frame;
    public static void main(String[] args)
        a.start();
public class frame1 extends Thread implements ActionListener
    //several public static variables/object for the frame etc.
    public frame1()
    public void run()
          //create the frame, add objects, add actionlisteners
    public void actionPerformed(ActionEvent e)
        //several buttons redirected to different methodes
    //several methodes
    public void end() //is called in a method
      frame2 p = new frame2();
       p.start();
    } This still works, but then:
public class frame2 extends Thread implements ActionListener
//several public static variables/object for the frame etc
    public frame2()
    public void run()
//create the frame, add objects, add actionlistener
      public void end()
            if(a)          //boolean a is true or false
                frame1 q = new frame1();
                q.start();
            else
                 frame3 w = new frame3();
                 w.start();
public void actionPerformed(ActionEvent e)
        //several buttons redirecting to different methods
} In the end method, "q.start();" gives the error. Am I doing something wrong? Shouldn't I be using Threads at all, should I try something different(what, how?)
I'm a student from The Netherlands, 18 years old, and I'm going to study "technische informatica" (don't know what it is in English, sorry, but it involves programming ;)). I've worked with Java on a low profile the last two years, learning & exploring, my most difficult application made is an ChatProgram (client/server based, in a local network). So this gives you my level in programming a little bit, I hope ;)
If someone is able to help me, please.

Also, how is pointing out that the path you are currently taking is pointless and a waste of time not helpful. At the very least it should cause you to stop even attempting to continue along that path, and prompt you to take a step back and try to look at the problem from another angle.
Jeesh, instead you just, essentially, say "Shut up! I know what I'm doing!". Well, that sounds like you really wanted help. Sounded more like you wanted confirmation, not help.
In any case, why don't you simply get rid of all references to threads, and simply change all but the main frame to JDialogs?
From what I can I see, of what you have posted here, that should be more than enough.
Just make sure, of course, that you don't mix your business logic into your GUI. Which you must have be doing currently, since a GUI class, in and of itself, has absolutely no reason to need it's own thread. It wouldn't help anything regardless of how you looked at it.

How to restart an interrupted thread ?

Hi All,
I have to stop a thread and then restart it after sometime. Since, stop() method is deprecated in jdk1.3 so, I m using interrupt() instead of stop() method. Can anyone please tell me , what does interrupting a thread exactly means? Does it termainates a thread completely or not?
Because , if I use thread.interrupt() and then thread.start() just after it, it raises exception java.lang.IllegalThreadStateException but still starts the thread.
Prime concern is how to stop and restart a thread without using stop() method??
Thanx and regards,
Shweta

You have to determine in the run method if the thread has been interrupted.
Usually like this
run()
while(!isInterrupted())
// code body
you could try this
boolean restart;
run()
while (true)
if (isInterrupted())
waitForRestart();
// code
waitForRestart()
restart = false;
while (!restart)
sleep(500);
restart(){restart = true;}

How to maintain the status of the Thread ?

How to maintain the status of the Thread ?
namanc

I want to know whether a particular thread (java
application) is completed successfully or not ...
If the thread is not completed successfully then I
want to restart the Thread.
Actually this is the Task Scheduler Application ...
If the particular task is not running successfully
then I want to start the Task again ...
namancThen it could look something like this: // loading the queue
for each task
    add task to list of incomplete tasks
    enqueue task in work queue
// dispatcher
while !done()
    task = workQueue.dequeue();
    New Thread(task).start();When a task finishes, it can call a callback method on the dispatcher. The dispatcher looks at the task's status. If it finished successfully, the task gets removed from the list of incomplete tasks. Else it goes back on the work queue.
There will be some syncing issues involved. You'll have to use wait() and notify()/notifyAll() to handle the situation where the work queue is empty, and all incomplete tasks are being worked on. And the case where the dispatcher wakes up after the notifyAll() and there's nothing to dequeue and nothing in the list of incomplete tasks.
Clearly it needs some fine tuning, but I hope you get the idea.

The problem about multi-thread in java application

i have problem with the multi-thread in java application, i don't know how to stop and restart a thread safely, because the function thread.stop(),thread.suspend() are both deprecated.
now what i can only do is making the thread check a flag(true or false) to determine whether to start or to stop, but i think this thread will always be in the memory and maybe it will lower the performance of the system, as the program i am developping is working under realtime enviorement.
please help me about it. thanks !

hi,
you can stop a thread by exiting it's run()-method which in terms can be done by checking the interrupted-flag:
public void run(){
while(interrupted()){ //if the thread consists of a loop
or
public void run(){
if(interrupted())return;
if(interrupted())return;
or by the use of the return-statement anywhere withing the run-method. Afterwards, that is when the thread is no longer needed, you clear all the references to the specific thread object by setting them to null:
Thread t;
... //working
t.interrupt(); //interrupting
while(t.isAlive()){
Thread.yield(); //wait till thread t has stopped
t=null;
best regards, Michael

Thread Pool Problem

Hi,
I amhaving problem with a thread pooling my code once allocates a thread to a user then never is able to find that it is idle. the code is some what like this.
public class foo extends Thread{
pubblic void setPrimeData(Hashtable data){
//sets the primary data
run()
this.isrunning = true;
//does something
this.isrunning= false;
}

You cannot restart a Thread. Once it has run, it cannot be reused. If you want to hand new tasks to threads in a pool, device some means by which you can hand a running (started) thread a new Runnable to execute in its run() method.

Need help stopping a thread

I have a thread that starts a file download. I tried using the following.
On the mouse click event of a button
thread.interrupt();
in the file download method
if(!thread.isInterrupted())
do stuff
else
thread.interrupted();
The way it stands now, the file download stops and everything seems fine. But I cant restart the thread. I read something about having to return from the run method but I cant get that to work.
Thanks,
Jason

interrupt is not a replacement for the deprecated stop. It performs interruption of waits and blocks. And sets a flag the next time the code in the thread hits a wait or block.
Your if else logic is unsafe wrt the use of interrupt.
You need to change the code to depend on a synchronized object with wait and notify
For example in the thread follow the motionObject:
    public LocateSampleThread(AerotechWrapper aerotechWrapper, double xScale, double yScale, double zScale, double φScale)
        this.aerotechWrapper=aerotechWrapper;
        //this.xScale=xScale;
        //this.yScale=yScale;
        //this.zScale=zScale;
        //this.φScale=φScale;
        this.motionObject=new Object();
        alarmEventListeners=new java.util.Vector();
        recoveredAlarmEventListeners=new java.util.Vector();
    public void run()
        int loopCount=0;
        while(!abort)
            try
                synchronized(motionObject)
                    motionObject.wait();
                    stop=false;
                if(abort) break;
                StateModel.getInstance().setState(StateModel.MOVING);
                try
                    StateModel.getInstance().setActive(StateModel.MOVING,true);
                catch(PropertyVetoException pve)
                StateModel.getInstance().incrementActiveThreadCount();
                System.out.println("LocateSampleThread "+StateModel.getInstance().getActiveThreadCount());
            catch(InterruptedException ie)
...do activity here.
            synchronized(motionObject)
                motionObject.notify();
            try
                StateModel.getInstance().setActive(StateModel.MOVING,false);
            catch(PropertyVetoException pve)
            StateModel.getInstance().clearState(StateModel.MOVING);
            StateModel.getInstance().decrementActiveThreadCount();
            sendStageMotionEvent (new StageMotionEvent (this, false));
    public void moveAndWait () throws InterruptedException
        synchronized (motionObject)
            motionObject.notify();
            motionObject.wait();
    public void moveAndDontWait ()
        synchronized (motionObject)
            motionObject.notify();
    protected Object motionObject=null;in the controlling code
                                try
                                    locateSampleThread.moveAndWait();
                                    //System.out.println("locateSampleThread notify/wait done");
                                    sleep(100);
                                catch(InterruptedException ie)
                                }Notice that the in moveAndWait the notify and wait ion the motionObject inside a synchronized is safe threading because the controlling code that calls moveAndWait will be waiting even before the thread's run(which is synchronized as well) starts going from being notified.

Need help with java thread program

Hi
I have an applet which does some painting etc, i need to write a thread which runs in background, and if there is no user activity for 30 min will refresh the screen.
I have one good thing that all user options go from one program so i know when user does some thing.
How do i write this thread program?
1. I need this program to start counter as soon as some activity is done by user
2. When user does some thing stop this thread
3. when user completes his action restart the thread with 30 min timer.
4. when there is no activity for 30 min refresh the screen
Any help will be really good
Ashish

Not sure what the problem is. Your pseudo code looks good to me.
The only suggestion I would make is that your use a Timer so you don't have to worry about creating your own Thread. You schedule a Timer to fire in 30 minutes. Everytime you have activiity you cancel the timer and reschedule it.

Does a thread can be declare once?

for example:
Thread thread = new Thread();
thread.start();
somewhere in my list code:
thread.stop_run();
thread.Interrupt();
i want to start thread again without:
Thread thread = new Thread();
thread.start();
just thread.start() and it will begin from the begining of a thread.
Is it can or not ???
thx....

You can not do that.
Once a thread is stopped, where yourThread.getState()==State.TERMINATED that thread can never be started again.
You can either just create a new instance of the thread like yourThread=new Thread(some class);
or you can avoid killing your thread in the first place. Once you're finished doing what you needed with that thread, put it to sleep for a long time like Long.MAX_VALUE. That thread will sleep until you interrupt it again.
To make sure the thread will execute from the beginning put the thread code in a infinite loop and use the continue command statement to reset the execution when you need to restart the thread.
In your code then every time you press a button or whatever starts the thread, first check the state of the thread if it's WAITING then just interrupt it, if it's NEW then just do what you regularly do.
It's probably easier to just create a new instance, but if you want to avoid that then try the above technique.

Stop Threaded stream reader reset

I have been trying to create a threaded search for looking through a comma delimited text file for a certain string section. The search uses a custom input stream reader which is currently declared in the thread class. The search works however I want to be able to find the next search result from the file. Obviously if I run the thread again the stream is reset to the start so my question is how do I declare the stream so it carries on from the previous position. Im thinking I have to declare it in a seperate class or something but am unsure, thanks for the help in advance.

I am not quite sure why you mention that it is a threaded search. I just cannot imagine how and why you would go about and search through an InputStream with multiple threads, so I assume you are just plain searching in an InputStream and this just happens in a separate thread from main.
Why is it that your custom InputStreamReader is reset when the thread is started? You seem to have full control, so just don't restart it. Make sure that the object is not just a field in the thread object that most likely is dismissed when the run() method terminates. Or just keep the thread object in a variable and reuse it instead of creating a new one when you want to restart the thread.

Passing date parameter from prompt

Hi experts
I am getting some problem while passing date from a dashboard prompt.
In RPD i have changed the date column properties as DATE only so that i will get the DATE part of the data not the time stamp.
Now in the dashboard prompt i added a prompt for the date column.
I initialized the date prompt with a server variable of sysdate
when i am running the dashboard i am getting default value in the prompt(04/15/2011)
when i am changing the date it is selected as(04/15/2011)
but when i am clicking the 'Go' button the date is converting to 2011-04-15 00:00:00 due to which my report is not running and i am getting error as
View Display Error
A date value was expected (received "2011-04-15 00:00:00").
Error Details
Error Codes: QABPH2PO
can anyone help me to pass only date part
thanks in advance
regards
Gourisankar

Hi J / Srikanth
Sorry to restart the thread again.
As we discussed i have downloaded the patch and applied to my windows 32 bit machine.
But now when i run the report the report is running only for the default value(Server Variable) which is specified to the prompt. when i change the date there is no effect to the report.
When i drill down to the report i found that the date column(is prompted) is changed to teh server variable name which is might be the cause.
any input on this???
regards
Gourisankar
