Running Background  java program

Hi Everybody,
I have written a client server application in java where in the client interacts with the user for some set of steps after which it calls the server method and waits for the response. During this i want the application to run in the back ground without the knowledge of the user. I am not sure whether this can be implemented but if its possible Can anybody please tell me how to do that?
Thanks a lot in advance,
Swetha

  • 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".

  • Is it possible to run a java program without using the command prompt?

    Hi,
    I was wondering whether it is possible to run a Java program (not an applet) without using a command line in the command prompt?
    Basically I want to run a program that will be continually running in the background and hence I don't want to have a command prompt screen loaded up as well - I just want the program to be running in the task bar.
    I know how to run the program in the task bar - but I still need to launch the program from the command prompt - is there anyway I can get a program running without having to start it from the command prompt?
    Cheers

    Or create a desktop shortcut (in Windows) or an application launcher ( in Linux GUI).

    Ok, let's see. Write the following class:
    public class Grunt {
      public static void main(String[] args) {
        System.out.println("Hello Mars");
    }Save it as "C:\Grunt.java", compile by typing:
    javac c:\Grunt.javaRun by typing:
    java -classpath "C:\" GruntDoes it say "Hello Mars"? If yes, go back to your program and compare for differences (maybe you used the "package" statement?).

  • Running a java program a set number of times

    This is a general question. Is it possible to make a java program run only 5 times for the sake of arguement.
    Basically I want to write a program that will give the user some flexibility when it will actually run another Java program, but I only want them to be able to say "not now' for a set number of times. When the last time comes the other program will launch. I was initially thinking of the Do Whilw loop, but this needs to work when the program is restarted.
    Program starts, it has 5 times it will run before it does something else(doesn't really matter now I think). User takes option "Not Now" and the program ends, but warns the user this will run 4 more times before you will need to do something.
    This process will repeat until the user takes the option "Ok install now" or the time limit expires and the install occurs anyway. Can someone point me in the right direction.

    ok I see so it's like one those programs that you download for free on the internet and they give you a set amount times to use it before you have to pay for it. but in this case when the number of times you use it equals 5 (or when the user clicks ok) a different java app will open automatically.
    My first thought would be to Write a Serialized object to disk using objectOutputStream that stores the number of times the application has been opened. and each time the program runs it checks for the serialized object and then you can do something like what I posted before. of course if were worried about security the user could always look for the object and erase it, if so then I guess we would have to come up with another plan of attack
    Hope this helps

  • 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?

  • Running a java program via a batch file

    I am unable to run a java program from a batch file that I created.
    spiderpackage.EntryPoint is a class file which I am trying to run with a -v option to output something.What should I do to get the output?
    echo ^<html^>^<body^>
    echo hello^<br^>
    call java spiderpackage.EntryPoint -v
    echo ^</body^>^</html^>

    This has nothing to do with java programming. Have a look at the windows help for the call command.
    The echo <html> stuff doesn't make sense. What's it for?
    The command in you batch file should be:
    java -cp . spiderpackage.EntryPoint -v
    assuming that java is in the system path, and the EntryPoint.class is in a directory called spiderpackage which is a subdirectory of your current working directory

  • Running a Java program at startup in Linux

    Hello
    How do I run a Java program at startup in Linux? I know in Windows I can put a .bat file in C:\Windows\Start Menu\Programs\StartUp\ directory, but in Linux I have no idea how it is done.
    Thank you,
    Mihai

    This is really a Linux question, not Java.
    And then it depends on the version of Linux you are using.
    Maybe this will help, otherwise you should try on a forum for your version of Linux.

  • Running a java program in a directory other than the current directory

    How do I run a java program that's located in a directory other than the current directory?
    There is a file Test.java in /dir1/subdir1. If my current directory is anywhere other than that directory, say /dir2/subdir2, I can compile Test.java by using:
    javac -classpath /dir1/subdir1 /dir1/subdir1/Test.java
    But when I try to run it with:
    java -classpath /dir1/subdir1 /dir1/subdir1/Test
    I get a java.lang.NoClassDefFoundError: \dir1\subdir1\Test
    Any thoughts?

    You need to specify just the name of the class you want to run. So java -classpath /dir1/subdir1 Test

  • Exception while Running a Java Program for UME.

    Hi Experts,
                           I am trying to run a java program to acess UME. Its a sample to create user but all of my samples are throwing this exception in NWDS  (Console).Can anyone tell me why is it throwing this exception .
    com.sap.security.api.UMRuntimeException: UME factory 'com.sap.security.api.IUserFactory' cannot be accessed because UME initialization has not started yet.
    Please check

    Hi,
    Earlier i faced the same exception when i tried to call the UME form Standalone java application,To resolve this i used stateless session bean approach. i follow the Below Mentioned Steps,
    1:-- create an J2EE -- EJB module project.
    2:-- Create stateless session bean and define the require methods ,implement Local and remote interface methods  in your bean class.
    3:-- refer the UME apis in EJB Projects build path.
    4:-- Call UME in Bean class methods.Build the EJB project and Archive.
    5:--Now create an Enterprise application Project ,Include the EJB module project to your EA Project by right clicking on EA project.Build EA project and EAR file
    6:--Deploy the EAR file on your server.
    7:--Now from your standalone java application include these two projects in Project tab of your Application.
    8:--Lookup the stateless session bean in your java class by its default JNDI name ,Obtain remote or local Home interface,And execute the BEAN Method which deals with UME.
    You can also refer this tutorial in some parts of it UME apis(like IUser,UMFactory) are used in Servelets and EJB ,You can download this tutorial source from SDN for your reference.

  • How to set path to run a Java program?

    my pc os is win2000 service pack 3.
    cpu is celoron 667mhz
    256 pc133 sdram
    i have done the setting b4 run a java program but no any effect.
    setting as below:
    set path=c:\j2sdk1.4.1_01\bin
    set classpath=c:\j2sdk1.4.1_01\lib
    my java file is store in C:\Java, file name is HelloWorld.java, so when i type:
    C:\>
    C:\>Java\javac HelloWorld.java
    (the screen show me : java\javac not internal or external........")
    and i try again as follow:
    C:>
    C:>\Java>javac HelloWorld.java
    (the screen show : Exception in thread "main" java.lang.NoClassDefFoundError:HelloWorld/java)
    i cant do anymore, who can help me?

    you need to put the CLASSPATH to dir: c:\j2sdk1.4.1_01
    and also to the directory you are working
    For example, you are working in "C:\Myclasses". You need to put:
    set CLASSPATH = C:\j2sk1.4.1_01;C:\Myclasses;
    if you don't put your working directory, java doesn't find your classes
    Try it and luck!

  • URGENT: How to run a Java program from a different directory?

    Hi.
    How do I run a Java program from a directory that the file is not located in? So lets say im in c:\Java. But the file is in c:\Java\abc\efg\.
    What would be the command to run the Java file from c:\Java.
    I can't remember it and I need it asap.
    Cheers.

    If the class you are trying to run is MyApp.class, try
    c:\Java\>java -cp abc\efg MyAppThe actual classpath you specify will depend on whether or not MyApp.class is in a package (I've assumed it isn't) and whether or not any 3rd party jars are involbed (I've assumed not).
    Edited by: pbrockway2 on Apr 1, 2008 6:42 PM
    The command arguments read as "Run the MyApp class using as a classpath abc\efg relative to here (c:\Java)".

  • How to run a java program without Java Compiler

    I have a small project and I want share it with my friends but my friend'pc have not
    Java compiler.
    for example, I writen a application like YM, then 2cp can sent,receive messege. My cumputer run as Server, and my frien PC run as client.
    How can my friend run it? or how to create an icon in dektop tu run a java program..??..
    (sorry about my English but U still understand what i mean (:-:)) )

    To run a program you don't need a Java compiler. Just the Java Runtime Engine. That can be downloaded from the Sun website and comes with an installer.
    You could then turn your application into an executable jar file and start it somehow like jar myYM.
    There is also software that packs a Java program into an executable file. I've never used that but one that comes to my mind is JexePack. It's for free if you can live with a copyright message popping up every time you start the program.
