Actually , i don't know how it will be active , so i have to using while (true)No, I'm pretty sure you don't need to. There are few cases where while(true) is needed and this isn't one of them.
but can't i using javascript to stop the java method ??Nope, not in the middle of a while loop.
or how to solve the problem ?What was your problem in the first place, what are you trying to achieve?

    I want to pass along a couple of tips that will get you more and better response on this list.
    1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
    2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
    3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
    4) If you have a question first search the examples for something tha
    t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
    5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
    6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"

  • How can i create messenger with java tv API on STB

    deal all.
    how can i create messenger with java tv API on STB.
    how can Xlets communicate each other?
    how?
    i am interested in xlet communications with java tv.
    is it impossible or not?
    help all..

    You can create a messenger-style application using JavaTV fairly easily. JavaTV supports standard java.net, and so any IP-based connection is pretty easy to do. The hard part of the application will be text input, but people have been using cellphone keypads to send SMS messages for long enough that they're familiar with doing this. This doesn't work well for long messages, where you really need a decent keyboard, but for short SMS-type messages it's acceptable.
    The biggest problem that you need to work around is the return channel. Many receivers only have a dial-up connection, ties up the phone line and potentially costs people money if they don't get free local calls. Always-on return channels (e.g. ADSL or cable modem) are still pretty uncommon, so it's something that you nee to think about. Of course, if you do have an always-on connection then this problem just goes away.
    This is really one of those cases that's technically do-able, but the infrastructure may not be there to give users a good experience.

  • How to use JavaScript Calendar with ADF Faces ?

    Hi All,
    Our application is running under limited bandwidth so that we want to use clientside/javascript calendar instead of the ADF Faces calendar (server side).
    I already have the javascript that will pop-up calendar selection dialog when invoked.
    Using JSP, this is working perfectly, BUT I don't know how to integrate this Javascript calendar with ADF Faces form.
    How can I do that ?
    Attached below is the JSP that works with script :
    <f:view>
    <html>
    <head>
    <script language="JavaScript" src="ts_picker.js">
    </script>
    <meta http-equiv="Content-Type"
    content="text/html; charset=windows-1252"/>
    <title>Calendar</title>
    </head>
    <body>
    <form name="tstest">
    <input type="Text" name="timestamp" value="">
    <img src="cal.gif" width="16" height="16" border="0" alt="Click here to get the date">
    </form>
    <h:form>
    </h:form>
    </body>
    </html>
    </f:view>

    Hi,
    ADF Faces does not provide a method that allows you to call JavaScript on the client. This may change in upcoming versions

  • How to control tcp connection with java tcp socket programing ??

    Hi,
    I am connecting a server as using java socket programming.
    When server close the connection (socket object) as using close() method ,
    I can not detect this and My program continue sending data as if there is a connection with server.
    How to catch the closing connection ( socket ) with java socket programming.
    My Client program is as following :
    import java.io.PrintWriter;
    import java.net.Socket;
    public class client
      public client()
       * @param args
      public static void main(String[] args)
        Socket socket=null;
        PrintWriter pw=null;
        try
                          socket = new Socket("localhost",5555);
                          pw = new PrintWriter(socket.getOutputStream(),true);
                          int i=0;
                          while (true)
                            i++;
                            pw.println(i+". message is being send.");
                            Thread.sleep(5000);
        } catch (Exception ex)

                            ex.printStackTrace();
                          } finally
    }

    I changed the code as following. But I couldn't catch the EOFException when I read from the socket. How can I catch this exception ?

        InputStreamReader inRead=null;
        InputStream in=null;
        try

                          while (true)
                            i++;
                            try
                              bufIn.readLine();
                              pw.println(i+". message is being send.");
                              System.out.println(i+". message has been send");
                            } catch (Exception ex2)
                              System.out.println(ex2.toString());

                            } finally
                            Thread.sleep(5000);
        } catch (EOFException ex)

    I have a nokia 6300 type s40v3

    I would like to know if it is possible to use a proxy of any and how ? kind with java applications.
    thank you

    Well, it works well when, into my applet, i do somethig like this:
    URL url = new URL(host);
    URLConnection connexion = url.openConnection();My applet uses proxy setting from IE6 but only if i use Java 1.4.2_08.
    With IE6 and Java 1.5.04, it doesn't work (my applet doesn't use proxy settings)
    With Firefox and Java 1.5.04, it's ok
    Have you already seen a problem like this with Java 1.5.04 ?

  • Servlet Communication with Java WebStart

    Hi there,
    we have an application that works fine with Java WebStart whenever we start it in a local area network. But from outside the LAN the application cannot communicate to it's servlets. I use the codebase IP address with the servlet runner's port (http://<codebase IP>:port/) as URL for servlet communication, but the application's request never reaches the servlets.
    My question is now, if anyone had the same or a similar problem with servlet communication using Java WebStart, or if anyone knows, if that might be a problem with proxy configuration.
    The servlet runner we use, is JServ from Sun (JSDK2.0) and the webserver where it is running on is not behind a firewall or a proxy, but the client PC with the web start application is.
    Thanks,
    Katja

    Thank you for your early reply. But I think, that's not the problem.
    I get no security error and the webserver is identified the same way it is in the jnlp file. Also my application is not running in the Sandbox. My assumption is, that the http-request to the servlet does not go through the proxy server between my PC and the PC the servletrunner is running on.
    I wonder if I have to configure my application to use a proxy server for communication with the servlets instead of the direct http-request to the servlet runner?

  • How to get php content with java ??

    i have made a php file what will display a number,
    here's a example
    <?php
    if ($action == "answer"){
    echo "18274926";
    ?>
    no i want to get the number with java
    so here's my java code
    import java.io.*;
    import java.net.*;
    import java.util.Date;
    class URLConnecties
        public static void main(String args[]) throws Exception
            int teken;
            URL url = new URL("http://www.gamer.mineurwar.nl/net/javachallenge.php?command=DaTe");
            URLConnection urlconnection = url.openConnection();
            System.out.println("Type inhoud: " +
                urlconnection.getContentType());
            System.out.println("Datum document: " +
                new Date(urlconnection.getDate()));
            System.out.println("Laatst gewijzigd: " +
                new Date(urlconnection.getLastModified()));
            System.out.println("Document vervalt: " +
                urlconnection.getExpiration());
            int lengteinhoud = urlconnection.getContentLength();
            System.out.println("Lengte inhoud: " + lengteinhoud);
            if (lengteinhoud > 0) {
                InputStream in = urlconnection.getInputStream();
                while ((teken = in.read()) != -1) {
                    System.out.print((char) teken);
                in.close();
    }if you change the url ro a .html file it displays the code correctly(source),
    but when trying to get the content of a php file (the number)
    it says that there is no content from the php file
    yhe source of the original php file what's in the code can be found at
    www.gamer.mineurwar.nl/net/javachallenge.txt

    The 'content' is generated dynamically by a PHP script so the "content lenght" can't be known in advance by the server. For this reason connection.getContentLenght() returns -1; it doesn't mean that there is no content, only that it can't be known how much there will be.
    To solve the issue, remove the if statement from around the while-loop:// if (lengteinhoud > 0) { DELETE THIS LINE
    InputStream in = urlconnection.getInputStream();
    while ((teken = in.read()) != -1) {
        System.out.print((char) teken);
    // } and this too
