Can I run my java program in windows environment?

How can i make my compiled java program run into windows environment?
What program will i use to be able to do that?

1. Install the JRE.
2. Go to the command line.
3. Type something like java myClass or java -jar myJar.jar.
You could also use one of the many java2exe (java to executable) programs floating out there.

    Hi all
    I want to run java program on windows environment as background processSo command prompt return after executing java command and program on background In Linux we can do this easily �but I do not how to do this in windows
    for example look this programe
    import java.io.*;
    import java.util.*;
    public class TestClass {
         class ravi extends Thread{
              public void run(){
                   try {    
                        String target_file = "ravind.txt";
                        File targetfile = new File(target_file);
                        PrintWriter writer = new PrintWriter(new FileWriter(targetfile)) ;
                   for (int i =0 ; i < 100 ;i++ ){
                        Thread.sleep(10000);
                        writer.println(" ravindra shukla ");
              } catch (Exception e) {               
                             e.printStackTrace();
         public static void main(String[] args) {
              TestClass test1 = new TestClass();
              TestClass.ravi r1 = test1.new ravi();
              r1.start();          
    System.out.println(" return from main ");
    first i compile this
    javac TestClass.java
    then i run this by using this command
    java TestClass
    but becouse i put sleep on threads run function so it takes to much time to get return on command promt .... i want to run this programe as background process so command promt return as soon as i execute java command

    Thanks dude
    This solution �start java TestClass� works fine �. But it does not solve my problem
    It opens another black window and that black window persist till the life time of my program
    Is it possible application run on complete background without opening another black window �as in Linux

  • How can i run my java program in background process?

    hi all,
    i am working on desktop monitoring so when i start my program on client machine that is visible to all but i want this program client not visible to all instead of this can be run in background process . so, nobody can see that.
    so, how i can do this ?
    pls pls help me
    thanks in advanced to helper
    regards
    maulik & ritesh

    this will run the java program in the background.It'll just use the Windows Java Console instead of the command-line console. It has nothing to do with running as a background process.
    Edit: though this might be exactly what the OP wants: not "background process" but "no DOS console".

  • How can I run a java program on Linux?

    I have JBuilder's IDE installed on my Linux partition and it works. However I don't know how to compile and test a program without it. Also I tried to install Limewire on Linux and although I've installed the Java SDK on the system. Once before I installed JBuilder and then JBuilder (I guess) installed it again. However it told me it couldn't find the Java Virtual Machine. Isn't this installed with the JDK? I am able to run programs through JBuilder so I can't see why I'd have a problem. Any answers to the above issues would be greatly appreciated.

    Go here and work out how to make a simple app to compile and run on the command line: http://java.sun.com/docs/books/tutorial/getStarted/cupojava/unix.html#2b
    (You should find the JDK from a directory under the jbuilder directory so use that and not the /usr/local/jdk1.4 in the example.)
    Then find the classes or source code of your project and do the same thing to it.

  • Opening a Word Document with a Java program in Windows

    When running a Java program in Windows, is it possible to have a button where when it is clicked it will open a Word document?
    If so, is it hard and can someone tell me how to do it??
    Thanks

    try this instead of Excel.exe you have to use Word.exe
    1. Declare your button
                   JButton butexlcom = new JButton("Carnet Offre");
                   butexlcom.addActionListener( new ButExlCommercial(msgout));
                   butexlcom.setBounds(215,510,110,30);
                   c.add( butexlcom );
    2. run your word document.
    class ButExlCommercial implements ActionListener {
         private JTextArea msgout;
         public ButExlCommercial( JTextArea msg) {

  • How can I run a java-application on starting of Windows 2000

    How can I run a java-application without any user on starting of Windows 2000?
    For example, if the computer is restarted and nobody enter into it yet, my java-application should run anyway.
    How can I do that?

    Hi, you have to put it in a Windows service.
    To do this you have a program, Srvany.exe that allow to insert a .exe or .bat program in a Windows service.
    For example, i develop a program, TomcatGuardian and i put it in a service because i need to run it in a server without Administrator logged in.

  • Can we run a java class in a external server through abap program?

    Dear Experts,
    Can we run a java class in an external server ( other than application server and client system )?
    I have tried running it in the client system through a program and it works.
    But i have the requirement of running it in another system. Can it be done?

    Hi,
    If this is the case I think you can call this web service from SAP and triger the execution of the application on the "external server".
    SAP is behaving as a client in this case.
    Another alternative:
    "have tried running it in the client system through a program and it works." please elaborate.

  • Running a java program from an icon

    I want to run my program from an icon on my desktop. I have a .bat file that I've built a shortcut to and it works.MY GUI program does display and run when I click on the icon. The problem is that the DOS window also shows up behind my GUI.
    Is there anyway to prevent the DOS window from showing? Or is there another way to run a Java program without resorting to a DOS command line or running it through FORTE or another IDD?

    Chris's solution worked well, with one small problem. Once my GUI starts, it takes up the whole screen. Normally when I run it, it appears as a small window.
    not a big problem, I can reduce it easily after it starts. But does anyone know a way to make it come up in the reduced size it norally comes up in when I run it from my IDE?
