Starting java program from a shortcut?

Each time I wan't to run a Java Application I need to do it from my IDE (eclipse).
Is it possible to just put a shortcut on the desktop and when double clicking it the program will run without opening eclipse?

This is a decent BAT creating BAT that i wrote.
it prompts for parameters
and then makes the Java run BAT automatically.
copy it into any text editor and then save it as ".bat" extension
change ProgramMain in the last "create batch" section to your
programs main class name. you can also easily look at this
bat and have it prompt the user for the main class name
and have it write it automatically.

  • How to run java programs from a master java program?

    Hello,
    I have several java programs which run from the command prompt. I am seeking help with code for starting java programs from within a java program. For example, a program called master.java works something like this:
    import java.*;
    create connection pool
    create variables and result sets
    start/run slave1.java (var1, var2);
    start/run slave2.java (var3, var4, var5);
    start/run slave3.java (var1, var4);
    end of program master.java
    Each of the slave.java programs will run for up to an hour. I do not want the master.java program to pause for each slave program to stop. Instead, the master program will keep running and multiple slave programs will be running simultaneously with the master program. When a slave program starts, it is on its own. Also, if possible, I would like to have each of these slave.java programs open in a new separate command window, so I can observe each slave program running in separate windows.
    Any suggestions for code or helpful documentation are greatly appreciated.
    Thank you,
    Logan

    Thank you all.
    At the bottom of master.java I have successfully started a batch file with these lines:
    String jcmd = "cmd.exe /c start c:/data/simulations/MsgViewCount2.bat";
    Process proc = Runtime.getRuntime().exec(jcmd);
    But I still cannot get a java program to start. Here is one variation I have tried:
    String [] cmdArray = new String[2];
    cmdArray[0] = "java";
    cmdArray[1] = "slave1";
    Runtime runtime = Runtime.getRuntime();
    Process process = runtime.exec(cmdArray);
    This compiles, and no errors occur, but nothing happens.
    Regarding this comment:
    Why Runtime.exec? Either make the slaves Runnable or
    just call their main() methods.
    Oh, I see. Sepearate output. :PNone of the slave.java programs have any output.
    Thanks again.

  • Not able to execute one Java program from another one via. exec()

    Hi,

    Hi diptaPB,
    Thanks for your suggestion.
    Here is how I tried it again, but not getting the desired output:
    Class Pr looks like below -->
    class Pr
    public static void main(String a[])
    System.out.println("hi from process");
    When I run 'Pr' from command prompt, i get the desired output:
    D:\batchwe>java Pr
    hi from process
    However, when I call 'Pr' from another program Ap2.java, it seems that it does not call 'Pr':
    class Ap2
    public static void main(String a[]) throws Exception
    Runtime rt=Runtime.getRuntime();
    Process p=null;
    String[] cmd=new String[2];
    cmd[0]="javac";
    cmd[1]="Pr.java";
    p=rt.exec("cmd");
    D:\batchwe>javac Ap2.java
    D:\batchwe>java Ap2

  • Calling one java program from another

    Hello,
    How can I start another java program from one? Lets
    say I want Second.java to start by calling it from
    First.java. How do I do it? The two programs are given
    below. Any help is appreciated.
    Thanks,
    Amanda
    First.java
    import java.io.*;
    import java.lang.reflect.*;
    public class  First
         public static void main(String[] args)
              Process theProcess=null;

    public class  Second
         public static void main(String[] args)
              System.out.println("Hello World from Second.java!");
    }

    Thanks, warnerja
    What if Second.java is on a remote machine i.e.
    First.java and second.java are on different machines?
    Will I have to use RMI?Well, you'd have to do some kind of remote invocation. Depends on what kinds of apps house the classes. There are all kinds of ways - web services, servlets, RMI, (maybe others...)
    That's a totally different question than what you originally posted, and would have been very relevant to say so in the first place.

  • Starting Java application from other Java application..

    Hi all,
    I was wondering if it is possible to start a Java program from an other Java program.
    In Java program 1, I have this code to execute the other application:
    try {
        Process p = Runtime.getRuntime().exec("cmd /c java -cp JavaApp2.jar com.test.TestFrame");
    } catch (IOException e) {
    }I tried this code, but unfortunately I couldn't opened the other (JavaApp2.jar) Java Application. Is there a way to open the other application anyways?
    I really hope someone can help me. Help would be greatly appreciated! Thanks in advance.
    Tongue78.

    What if there is no JAR file?Then you can make it out of the .class files. And to anticipate your next question, if there are no .class files there is no application at all, so you can't exec() it or call the main() method directly. Your point?
    And JAR isn't part of the Java language.It is a major part of the Java platform.
    This means you can only get access to a JAR file via the OS. Wrong again. CLASSPATH. URLClassLoader.
    In short you cannot just shout main() in a Java program and hope some other Java program will hear you and start.Absolute rubbish. If the required classes are on the CLASSPATH you just call com.company2.app2.main(args) and off you go. Or you can load the main class and invoke its main() reflectively.
    No source code required, or 'source code merge' either.

  • Executing a Java Program from within a Java Program

    I need to execute the following Java Program from withing another Java Program. The office toolbar command line is
    D:\WINDOWS\system32\java.exe -cp E:\Development\Eclipse\UpdateServer\Classes -server -showversion UpdateServer
    I can find no combination of ProcessBuilder commands, including those that include "Cmd.exe /c" that will make this program run from within another Java Program. All the examples I can find only show how to run Windows *.exe programs. I keep getting error 123 from ProcessBuilder.start(), but I can find no documentation for error 123.

    Assuming your code didn't get mangled by the forum
    (it's missing one "), it may be that your "-cp
    E:\\Develop.." argument is getting quoted as it has a
    space in it; try passing "-cp" and "E:\\Develop..."
    as two arguments.That worked; specifically the following tested OK:
    ProcessBuilder pb = new ProcessBuilder("D:\\WINDOWS\\System32\\Java.exe", "-cp", "E:\\Development\\Eclipse\\UpdateServer\\Classes\\", "-server", "-showversion", "UpdateServer" );
    pb.directory(new File("E:\\Development\\Eclipse\\UpdateServer\\Classes\\"));
    try{
         Process p = pb.start();
         InputStream is = p.getErrorStream();
         InputStreamReader isr = new InputStreamReader(is);
         BufferedReader br = new BufferedReader(isr);
         String line;
         while ((line = br.readLine()) != null)
              System.out.println(line);
         p.waitFor();
    }catch(IOException ioe){
    I was sure I tried that exact same code before, and it did not work, but now it does, at least at the top level (when it is in main of a test program). I will have to wait to try it until later when it is buried deep in a subroutine.

  • Error while calling java program from ABAP

    Hi Experts,
    We are trying for RFC inbound scenario.
    We followed the below blog
    /people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
    We are working with SAP JCO 3.0.2
    We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
    After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
    If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
    But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
    'STFC_CONNECTION' could not be found in the server repository.
    If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
    'RFCPING' could not be found in the server repository.
    We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
    Please help us in resolving this issue.
    Thanks

  • 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)".

  • Execute a java program from an another program

    Like we can compile a code from wihin a java file by using the following :
    Tool javac = ToolProvider.getSystemJavaCompiler();
    Similarly,can we execute i.e. run a java program from within a java file i.e. running d java command from within the java file ??If yes then please tell me how??

    suppose on the Unix box or from a Unix script ( korn, perl, bourne, bash) you can run the following java program
    java ${JAVA_OPTS} -jar ${GMR_APPS_DIR}/risk.jar -I -c ${COB} -r ${BATCH} -o ${XML_DIR}
    in java you can do the following :
    Runtime rt = Runtime.getRuntime();
              try {
                   Process process = rt.exec("java ${JAVA_OPTS} -jar ${GMR_APPS_DIR}/risk.jar -I -c ${COB} -r ${BATCH} -o ${XML_DIR}
    // OR
                   Process process = rt.exec("/export/apps/Tools/apache-tomcat-5.5.17/bin/startup.sh");
                   // process.destroy(); if you want to kill the process
                   process.waitFor();
                   int RC = process.exitValue();

                   BufferedReader br = new BufferedReader(new InputStreamReader(is));

                   return strBuff.toString();
              }You need to relace the ${} by the appropriate values.

    This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
    Implement an RFC server in 7.0:

  • How to protect java program from hotspot sa

    I tried several methods(eg. custom classloader、jvmti) to protected my java program from decompile. They work well until meeting hotspot sa. "Hotspot sa classdump" is so powerf that it can directly dump class from java process's memory in a non invasive debug mode, which make any protect method useless. Is there any way to protect from "hotspot sa classdump"?

    There's really no secure way to protect code, in the way that you imagine.
    However, your code is most likely not so important that it matters (if it were important, you would already know that it's impossible to give your code away to someone and protect it at the same time).
    Of course if you provide your software as a service, the code is never executed by the client and he can't decompile it. Of course not all software can be provided as a service.

    I rather thought about RMI. But I could try servlets. So how it would look like?.
    I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
    But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.
