End Thread -- Urgent
Hi,
Let's said i have an applet that do a upload file. When clicking on the "upload" button, it starts to read a file and send each line to a serial port. And I have a "Cancel" button that I could click on durint the upload to cancel the upload...But the click on the "cancel" button is only performed after my upload end...
What should I do to performed the Cancel Upload during my upload session?
thx
just close the stream

if (!closed)
baos.wait();
}Which acquires a lock on baos, then tells its own thread to wait without ever relinquishing its lock on baos. So when your main method calls the read method, it hangs immediately when it tries to access baos because it is still locked. So what you're seeing is a basic deadlock condition.
Really, you're not gaining anything with your multithreading in this case. But that's a different issue. -

RMI and Threading: Urgent, pls help!
Hi everyone,
I read the previous topics in multithreading but i'm still confused about how RMI works in this case.
I have a client server application with RMI where client runs some time-consuming executables on the server.
(i use Process proc = Runtime.getRuntime().exec(cmd...)...)
Basically I want to make sure that simultaneous requests from different clients execute concurrently, instead of waiting for each other to finish. So my questions are:
1) When mutiple clients are making remote calls, does RMI map each client request to separate thread and execute them simultaneously (if yes, does it have some limit on number of threads that can be created?);
Or will I have to take care of creating threads on the server side for each request myself? if the later is the case, how could I go about doing that?
2) What if all (or some of) the clients are connected from the same VM? How can I ensure that they get executed in different threads, concurrently. Could you pls direct me to ways of implementing it.
any help is greatly appreciated,
yulduz1) When mutiple clients are making remote calls, does RMI map each client request to separate
thread and execute them simultaneously (if yes, does it have some limit on number of threads
that can be created?); Yes, RMI takes care of launching a thread on each remote call. It actually maintains a pool of threads from which, a free thread is assigned a new request. From then on, you have different threads running in server VM (one per each client call).
Or will I have to take care of creating threads on the server side for each request myself? if the
later is the case, how could I go about doing that?No, you dont have to create any thread just for the purpose of handling a remote call.
2) What if all (or some of) the clients are connected from the same VM? How can I ensure that
they get executed in different threads, concurrently. Could you pls direct me to ways of
implementing it.You dont have to do anything extra for achieving this. It doesnt matter whether you are running clients in the same VM or different VMs. If you want concurrency on the client side, you have to make remote calls from different threads. The following code outlines the difference between concurrency and non-concurrency in client VM (and NOT server VM).
class CallerThread extends Thread {
public void run() {
remoteRef.callMethod();
public class Client {
... main() {
// these are not concurrent in client VM bcos the second call happens only after first one returns
remoteRef.callMethod1();
remoteRef.callMethod2();
CallerThread t1, t2;
// these two calls are concurrent on the client side as they're called from two different threads
t1.start();
t2.start();
}regds,

hi all,
i have an application which forks out one or more threads.now if in between i need to save information and close down one thread what do i do.There are many ways to keep a reference to your Threads. You can use an array, a Collection, or in the code below, I hold a reference to the Threads in a DefaultListModel, which is used by a JList to show the Threads that are running.
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

private JList list;
private DefaultListModel model = new DefaultListModel();
public App() {
this.list = new JList(this.model);
JScrollPane scrollList = new JScrollPane(this.list);
JButton startButton = new JButton("Start");
JButton stopButton = new JButton("Stop");
this.getContentPane().setLayout(new FlowLayout());
this.getContentPane().add(startButton);
this.getContentPane().add(stopButton);
this.getContentPane().add(scrollList);
startButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
startPipelines();
stopButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
stopSelectedPipelines();
public void startPipelines() {

this.model.addElement(pipeline);
pipeline.start();
public void stopSelectedPipelines() {
Object[] pipelines = this.list.getSelectedValues();
for (int j = 0; j < pipelines.length; j++) {
((Thread) pipelines[j]).interrupt();
this.model.removeElement(pipelines[j]);

Hi,
I am not sure i am posting this in the correct area. Please bear and advice.
My application needs to run a thread contiuously for every 1 hr. I have made the coding in servlet as
package invservlet;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
import java.util.Timer;
import java.util.TimerTask;
import java.util.Date;
import java.util.Calendar;
import sample.Reminder;
public class SampleReminder extends HttpServlet{
Timer timer;
Date date=new Date();
Calendar calc=Calendar.getInstance();
public void init(){
timer = new Timer();
timer.schedule(new Reminder(),calc.getTime(),1*1000*60*60);
public void doService(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{
public void destroy(){
timer.cancel();
super.destroy();
and the execution file is
package sample;
import java.util.TimerTask;
import java.util.Date;
import box.util.SendMail;
public class Reminder extends TimerTask{
SendMail sendMail=new SendMail();
public void run() {
taskBody();
public void taskBody()
try{
sendMail.SendMail("192.168.0.33","[email protected]","[email protected]","","","Test log mail","This is a test mail for every 1 hour"+new Date());
}catch(Exception e){System.out.println("ERROR IN Remainder");}
BUT EVERY 2 - 3 DAYS I AM GETTING MY TOMCAT HANGING. I THINK THE PROBLEM IS IN THE THREAD. PLEASE ADVICE. THANKS.Sorry, forget to add some more points which may help for analysation.
My application will fetch more than 1000 records for single transaction.
And also some times in will be transferred (sendRedirect) to another page with nearly 20 fields of data.
Will this also create problem? -
HI SAP Gurus
we are going to apply SAP notes , today do i need any furthur configuration required for that or SPS will already configured, plese help me out
thank you in advanceHello Goutham,
Kindly clarify whether you are taking about Payroll US or Payroll Canada,
If it is Payroll US,
then all the relevant note's and HRSP Level is document in the year end page
"Service.sap.com/hrusa" --> Year end
Also you can put watch this thread for year end thread for payroll US
"US - Year End 2011
If it is Payroll Canada,
then all the relevant notes and HRSP Level is document in the year end page
"service.sap.com/hrcanada" --> Year end

Thread problem or jvm problem?
Hello, I've posted message on this link and now I've finished my project. Now, I have a different problem: that's why I'm posting this message here.
if you want me to post my project code, I can , but I think it's not necessary for now... So, there are 5 classes; Main, Thread1 extends Thread, thread2 extends Thread, Thread3 extends Thread and ThreadFactory... in main method; factory instance is called for the creation of threads; so in main three type of thread instance created by factory. And right after that threads starts running and thread1 finished first, thread2 finished second, and thred3 finished third; However, the program itself never ends. There is a problem with thread endings. I've also make dubugging. Main thread creates the three of them and first main thread finishes second thread1 and the other three never finishes... keeps running.
when main thread end it's state becomes zombie and thread1 also becomes zombie tooo.... but the other 2 of them never ends. I've tried may� things to do that: I've used finalyze() method too. Nothing chanced.
I guessed that this may happen becouse of JVM... so what do you suggest for ending threads in a sequence like thread1, thread2, thread3, main?no help?

URGENT : replacing letters in an expression
Hi all
I think that I should post this topic here because I think it concerns SQL functions. Here is the problem :
I am developping a forms application . There is a listbox named FORMULA containing list of formulas. When I choose a formula from that list then there is a program which exctracts all of its operands. For example if the formula is : (a+b)*abs(c-d) then the operands are : a,b,c and d.
Then I populate another listbox named OPERANDS with these operands. So the value of the OPERANDS listbox is either a or b or c or d in our example.
I held the expression of the formula in a global variable so it can be accessible anywhere in my application.
When I choose one of the operands from the OPERANDS listbox , for example b,then I enter its value , for example 5, in a text field named VALUE ,and then I click on a button to replace the letter "b" in the formula with the value I entered , which is 5. So I want to get an expression like this : (a+5)*abs(c-d) .
But the problem is that when I run the application then all letters "b" in the formula are replaced by 5 . So even the expression "abs", which is a pl/sql function, is replaced by "a5s". And I do not want that to happen.
Here is how I proceeded :
formula := replace(formula,operands,value); where "formula" is the global variable containing the formula expression, "operands" is the variable containing the value of the OPERANDS listbox which is "b" here, and "value" is the variable containing the value 5.
So how can I avoid this misreplacement ?
Thank you very much indeed.post it where you want, but only once...
I will follow the other thread

Confusion using Thread.sleep() method
I tried it in this program
class NewThread implements Runnable {
String name; // name of thread
Thread t;
NewThread(String threadname) {
name = threadname;
t = new Thread(this, name);
System.out.println("New thread: " + t);
t.start(); // Start the thread
// This is the entry point for thread.
public void run() {
try {
for(int i = 5; i > 0; i--) {
System.out.println(name + ": " + i);
Thread.sleep(1000);
} catch (InterruptedException e) {
System.out.println(name + "Interrupted");
System.out.println(name + " exiting.");
class MultiThreadDemo {
public static void main(String args[]) {
new NewThread("One"); // start threads
new NewThread("Two");
new NewThread("Three");
try {
// wait for other threads to end
Thread.sleep(10000);
} catch (InterruptedException e) {
System.out.println("Main thread Interrupted");
System.out.println("Main thread exiting.");
}the output is
one: 5
two: 5
three 5
delay of 1 second
one:4
two: 4
three: 4
delay of 1second
what all i know about sleep() is that it pause the currently executing thread for specified time. hence in above program when first thread runs and prints value 5 then it should get paused for 1 second cause there is Thread.sleep(1000) after println() statement.
and output should be
one: 5
delay of 1 second
two: 5
delay of 1 second
three: 5
delay of 1 second
but this is not actually happens. may be i am wrong about Thread.sleep method() or something else.
would you guys please clear it?
regards
sanThread.sleep() only sleeps the current thread. As each thread runs concurrently they all print concurrently and all sleep concurrently.

Surprisingly fast locking of single thread
The question in this thread
http://forums.adobe.com/thread/1080275?tstart=0
was correctly answered within two minutes by Bill, and his answer was marked as correct and the thread locked, probably shortly after Bill's posting.
What I find susprising is that the Reader forum has hundreds of similar questions and answers (see Pat's complain here http://forums.adobe.com/thread/1079699?tstart=0) , but only a handful of them are marked as Answered. And, without checking, I would say that (almost) none of these threads have been locked.
Bill, was that you?Locking dead-ended threads is one tool we can use to maintain an effective customer experience. Experts on the forum tend to ignore answered questions precisely because they're answered, so thread-hijackers have much less chance of getting help compared to when they post a new question. As Bill and John have said, if someone searches the forums for a keyword and hits one of the threads that were started in the wrong place we absolutely do not want them replying to it.
Locks are applied for three basic reasons:
The thread is in the wrong place and couldn't be moved due to lack of information (outright duplicate posts are removed when they're noticed - please report any you find).
The thread has deviated from the original topic or has violated the Guidelines (e.g. it's descended into a slanging match).
The post is for information only (e.g. FAQ pages).
If there is an active and pertinent conversation within a thread it won't be locked, even if a Correct reply has been selected, but there are some threads which are so old or so trivial there's no reason anyone should reply to them. These forums are used for internal reporting and it assists with that process to have a number of similar-but-separate questions in the database as opposed to one thread with several conversations crossing each other.
There are some forums which are read-only, e.g. legacy or beta versions of software, but there will always be a new and open forum for current issues if the product still exists.
Current policy is for hosts to assign a Correct status to answers as and when they are identified, allowing time for the OP to make the decision first. Historically we didn't do this so there are hundreds of thousands of old threads which are 'answered' but not marked as such. It's a very long process to go through and retag them - and there's little benefit from doing so. -
Urgent: ORA-04030 from PL/SQL code
Hi, we are running a data conversion program for Oracle Applications which works in the following logic
1. There is a loader program which uses SQLLoader to load 6.6L records from flat files to custom staging table
2. There is a Validation program which validates (for business requirements) records available in the custom staging table. Based on the validation results the program updates the Status field (a column of the table) to ERROR or SUCCESS. This program uses pl/sql table types with bulk insert and bulk update. While we run the program for less number of records it works fine, but when the volume of data is high (6.6L) we get the following exception:
ORA-04030 (out of process memory when trying to allocate ... bytes).
As an work around we have used "dbms_session.free_unused_user_memory;" statement after every plsql table.DELETE call. But still we get the issue. Can anyone suggest us whats going wrong? If we use of Global Temp Table in place of pl/sql table will it help?
Thanks /SantanuDuplicate Thread
