How to stop single VU, java-code

Hi,
Is there a way to stop a single VU?
E.g:
if (condition){
stop iterating;
Regards

public void run() throws Exception
    boolean stopIt = false;          
    if (stopIt)
        IteratingVUser vu = (IteratingVUser) this.getScriptVUser();
        vu.stop();
        return;
}

  • How to 'STOP' a running java thread in J2ME?

    Dear All,
    How to 'STOP' a running java thread in J2ME?
    In the middleware viewpoint, for some reasons we have to stopped/destroyed the running threads (we have no information how these applications designed).
    But in J2ME, Thread.destroy() is not implemented. Are there other approaches to solve this problem?
    Thanks in advance!
    Jason

    Hi jason,
    Actually there are no methods like stop() and interrupt() to stop the threads in J2ME which is present in normally J2SE Environment.
    But the interrupt method is introduced in Version 1.1 of the CLDC.
    So, we can handle the thread in two ways.
    a) If it is of single thread, then we can use a boolean variable in the run method to hadle it. so when the particular boolean value is changed , it will come out of the thread.
    for eg:
    public class exampleThread implements Runnable
    public boolean exit = false;
    public void run()
    while(!exit)
    #perform task(coding whatever u needed)
    public void exit()
    exit = true;
    b) If it is of many threads then we can handle using the instance of the current thread using currentThread() method
    for eg:
    public class exampleThread implements Runnable
    public Thread latest = null;
    public Thread restart()
    latest = new Thread(this);
    latest.start();
    public void run()
    Thread thisThread = Thread.currentThread();
    while( latest == thisThread )
    #perform some tasks(coding part);
    public voi d stopAll()
    latest = null;
    while ( latest == thisThread )
    performOperation1();
    if( latest != thisThread )
    break;
    performOperation2();

  • How to calling JVM in java code

    Hello!
    I continued my homework -- a java IDE written in java. I've asked how to compile the java code in my IDE here. Thanks to Franck_Lefevre, he showed me this:
    import com.sun.tools.javac.Main;
    public static boolean compileSource(String filename) {
    String[] javac_args = { filename };
    int result = Main.compile(javac_args);
    return (result == 0);
    now the problem is how to RUN the .class file on the JVM. Is there a method corresponding to this, ie also using java tools? or some better ways? I've tried a few ones but they don't work well.
    I really appreciate you who helped me so much.

    Planetar, remember to read the API docs for the
    complete method signature for Class.getMethod.Good point, take my code example as just a rough guide of what to look at in the API docs. Namly,Class, ClassLoader and Method.

    Say me a tip!

    But I don't know how to.
    Basic flow is :

    and the java module call a reports RDF with parameters
    I don't need reponse message from rwcgi60 or rwrun60.

  • How to execute a custom java code from the process

    Hi All,
    I'm writing a process to generate the PDF and it works fine. Now, at the end or in the middle of the process, i would like to execute/write a java code then it will be invoked when the process running. Assume not using web service, is there another way? samples how to write custom code?
    Thanks,

    The Execute Script service allows you to execute java code on a particular step.
    A more robust solution would be to create a custom component for your custom code.

  • How to generate single signature for code signing and timestamp

    Hi we are developing Win 7 VC++ app using Crypto APIs.
    Here code signing is done using Cryptsignhash() method, that generates the signature. Later for time stamping CryptRetriveTimestamp() method is used which also generate the time stamp signature. Thus we wanted to know
    whether there is any single Crypto API available that can do code signing and timestamping together and shall generate single signature. At verification side it should be also possible to separate code signing and timestamp signatures prior to verification.
    Any help is highly appreciated. Thanks.

    No. Normally, you don't counter-sign the actual data - you counter-sign and time stamp your signature. You don't want to transmit the whole data (which could be a) large and b) confidential) to a third party. This is why it's a two step process.

  • How to stop a daemon Java Thread?

    If I have a thread set as daemon and the main program has already exited, how do I locate the thread to stop it?
    Thanks.

    > As for stopping it you use a socket and send it a message. That of course would require another thread because it is a listener.
    Could you explain me a little bit more this (or send a link)? That is probably what I want to do. I want to open another instance of the program and stop the running thread. (By the way I'm doing this on Windows).
    Daemon thread != unix daemon.
    I'm not actually setting the thread as deamon because I want it as a background task, but because I want the main program to exit after it has started the thread and I want the thread to keep running. I read somewhere that I could do this setting the thread as daemon. But I misunderstood what I read.
    Again, what I want to know if there's a way of running an app that when you press a start button, for example starts a thread that performs some ops. and exits, but the thread is still running, and if you re-open the app and press the stop button it stops the running thread, that is, the instance of the app that created the thread is not the one who's going to stop it.
    I don't necesarily want to do it using threads but that was the way I first thought of.
    Thank you for your reply :)
