Problem using Runtime.exec()

hi all,
I have a problem in executing the program which in turn runs the batch file which to deploy an EJB in IAS(application server).
pls go through the code
import java.io.*;
public class ExeBat
public static void main(String[] args)
try
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("dsg07.bat VitalsignsGroup");
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader in1 = new BufferedReader(new InputStreamReader(p.getErrorStream()));
int s = in1.read();
while(s!=-1)
System.out.print((char)s);
s = in1.read();
     catch(Exception e ){System.out.println(e);}
In this program dsg07 is the batch file that executes deploys an ejb and VitalsignsGroup is the name of the jarfile. During the execution this Jar file is used to generate the stubs and skeletons during which it hangs.
I hope u understood my problem and will suggest the solution.
Thanks In Advance
Parimala

try running it as Runtime.getRuntime.exec("cmd abc.bat vitalgrp"

  • Problems with runtime.exec()

    Hi All,
    I am having a problem using runtime.exec()
    in servlet to call a java file from the server.The server is a linux one and i am using a tomcat server-4.1.24 the server contains
    some java files which i need to invoke with the help of the servlet program so i try to use exec() in servlet to invoke a particular java file in the server.The program is compiling well but no information
    is displayed on the browser.Where in the servlet program i try to print the details of the particular java program that is in the server.For ur
    reference i will post the code :-
    import javax.servlet.http.*;
    import javax.servlet.*;
    import java.io.*;
    public class ExeServlet extends HttpServlet
    public void doGet(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
    try
    String path = getServletContext().getRealPath("/var/jakarta/webapps/examples/WEB-INF/classes/ServletExample.java");
    /*Where it is the path of the java file that resides in the server machine(linux)Which i want to invoke and print its details on the browser*/
    Runtime runtime=Runtime.getRuntime();
    Process proc=runtime.exec(path );
    BufferedReader br=new BufferedReader(new InputStreamReader(proc.getInputStream()));
    res.setContentType("text/html");
    PrintWriter pw=res.getWriter();
    pw.println("<b>");
    String line=null;
    while((line=br.readLine())!=null)
    { pw.println(line); //Displaying the details of the ServletExample.java file in the browser
    pw.println("</b>");
    catch (Exception e)
    pw.println("Listener *not* started!");
    What is the problem here?I was so frustrated with this.Pls. do provide an immediate reply if there is any code regarding this is working pls. do provide it.It is Urgent.I will be waiting for ur reply.
    Thanx,

    Hi Leo,
    Thank u for the reply i still have the problem with exec() in servlets.Has i said earlier in my previous mail by using exec() i trying to execute the output of a c-program for eg,Hello.run which provides an output of "HelloWorld" which is a sample eg.The Hello.run is the directory /var/jakarta/webapps/examples/WEB-INF/classes which is also the directory where my servlet program is.Where i am using a tomcat server-4.1.24 on the linux machine 7.3.Which is the server ofcourse.
    Here by using a servlet program i try to exceute the Hello.run c-program and display the output in the browser.This is what i need to do.
    I also used a sample core java class put the exec() there in a method and i try to call the method in the servlet.Which is also not working.
    Here is that example :-
    The core java program:-
    public class UsingExec
    public String ExeDisplay()
         try
    System.out.println("ExeDisplay");
         Runtime rt=Runtime.getRuntime();
         Process p=rt.exec("/var/jakarta/webapps/examples/WEB-INF/classes/Hello.run");
    p.waitFor();
    return "true";
         catch(Exception e)
    return "false";
    public static void main(String args[])
    UsingExec ue=new UsingExec();
    ue.ExeDisplay();
    When i run this program only ExeDisplay at the top is displayed.
    Here is the Servlet program:-
    import javax.servlet.http.*;
    import javax.servlet.*;
    import java.io.*;
    public class ExeServlet extends HttpServlet
    public void doGet(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
    try
    res.setContentType("text/html");
    PrintWriter pw=res.getWriter();
    UsingExec ue=new UsingExec();
    String line=ue.ExeDisplay();
    pw.println(line);
    catch (Exception e)
    When i display this program on the browser only "false" is displayed from the UsingExec.java & nothing is displayed.
    Thanx,

  • Problem of executing a process under Linux using Runtime.exec

    Hi, All
    I am having a problem of executing a process under Linux and looking for help.
    I have a simple C program, which just opens a listening port, accept connection request and receive data. What I did is:
    1. I create a script to start this C program
    2. I write a simple java application using Runtime.exec to execute this script
    I can see this C program is started, and it is doing what it supposed to do, opening a listening port, accepting connection request from client and receiving data from client. But if I stop the Java application, then this C program will die when any incoming data or connection request happens. There is nothing wrong with the C program and the script, because if I manually execute this script, everying works fine.
    I am using jre1.4.2_07 and running under Linux fedora 3.0.
    Then I tried similar thing under Windows XP with service pack2, evrything works OK, the C program doesn't die at all.

    Mind reading is not an exact science but I bet that you are not processing either the process stdout or the stderr stream properly. Have you read http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html ?

  • Can we run a java application using Runtime.exec()?

    Can we run a java application using Runtime.exec()?
    If yes what should i use "java" or "javaw", and which way?
    r.exec("java","xyz.class");

    The best way to run the java application would be to dynamiically load it within the same JVM. Look thru the class "ClassLoader" and the "Class", "Method" etc...clases.
    The problem with exec is that it starts another JVM and moreover you dont have the interface where you can throw the Output directly.(indirectly it can be done by openong InputStreams bala blah............). I found this convenient. I am attaching part of my code for easy refernce.

  • Trying to run external script using Runtime.exec

    Hey,
    I am trying to use Runtime.exec(cmd, evnp, dir) to execute a fortran program and get back its output, however it seems to always be hanging. Here is my code snippet :
                Process process = Runtime.getRuntime().exec(
                      "./fortranCodeName > inputFile.txt" , null, new File("/home/myRunDir/"));
                InputStream stream = new InputStream(process.getInputStream());
                InputStream error = new InputStreamr(process.getErrorStream());
                BufferedReader stdoutReader = new BufferedReader(new InputStreamReader(stream));
                BufferedReader erroutReader = new BufferedReader(new InputStreamReader(error));
                System.out.println(stream.available());  //returns 0
                System.out.println(error.available());     //returns 0
                while (true) {
                    String line1 = stdoutReader.readLine();  //hangs here
                    String line2 = erroutReader.readLine();
                    if (line1 == null) {
                        break;
                    System.out.println(line1);
                    System.out.println(line2);
                }I know for a fact that this fortran code prints out stuff when run it in terminal, but I don't know if I have even set up my Runtime.exec statement properly. I think I am clearing out my error and input streams with the whole reader.readLine bit I have above, but I am not sure. If you replace the command with something like "echo helloWorld" or "pwd", it prints out everything properly. I also am fairly confident that I have no environmental variables that are used in the fortran code, as I received it from another computer and haven't set up any in my bash profile.
    Any Ideas?

    Okay, so I implemented the changes from that website (thanks by the way for that link, it helps me understand this a little better). However, my problem is still occuring. Here is my new code:

                String type;
                StreamThread(InputStream is, String type)
                    this.is = is;

                public void run()
                    try
                        InputStreamReader isr = new InputStreamReader(is); //never gets called
                        BufferedReader br = new BufferedReader(isr);

  • Launching another VM instance using Runtime.exec()

    Hi,
    I have two separate Swing applications, say A and B. I need to launch B from A using Runtime.exec() - essentially I am launching another VM instance from one VM. I am encountering strange problems - B's main window comes up, but GUI doesn't update; sometimes B comes up and GUI updates, but huge memory leaks happen. All the problems with B go away once A is shut down. It almost looks like both the instances of VM are sharing (or competing for) the event thread. Any comments will be of great help. Thanks.
    note: There is no problem launching B if A is a console java application (i.e. no Swing GUI).

    I have recently had the same problem, especially with the part where it seems like the two applications are sharing or competing for the same event thread. Sometimes my application B hangs like it is stuck waiting for an event. Sometimes I can get it to unhang by moving the app window around or minimizing it. If it does break free, all the queued events occur in rapid succession. Anybody have any clue what's going on here? It's pretty annoying.

  • Opening a new browser using Runtime.exec()...

    I am trying to open a new IE browser window (from Windows) using Runtime.exec( ) command. The problem is that it uses the existing browser window instead of opening a new window. (opens a new window only if there isn't any other browser window)
    Here is the snippet of code that I am using to do this:
    String WIN_PATH = "rundll32";
    String WIN_FLAG = "url.dll,FileProtocolHandler";
    String url = "http://www.cnn.com";
    String cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
    Process p = Runtime.getRuntime().exec(cmd);
    Thanks in advance.

    If you're app. opens a page that you control, it can be done from the web page. See [Have a Java button close the browser window|http://www.rgagnon.com/javadetails/java-0282.html] or the JS based [Close the browser|http://www.rgagnon.com/jsdetails/js-0079.html].
    If you do not control the page, don't close it - the user knows where the little 'x' button is.

  • How do I copy a file to a remote server using runtime exec - plz Help!

    Hi,
    I am trying to copy a file to a remote server using a runtime exec command as follows:
    Runtime.getRuntime().exec("scp "+getProperty(ListNewHandsetDetailsConstant.PROP_OUTPUT_PATH_JAR)+getProperty(ListNewHandsetDetailsConstant.PROP_OUTPUT_JAR_NAME)+".jar "+" "+getProperty(ListNewHandsetDetailsConstant.PROP_OUTPUT_PATH_TWO_USERNAME)+"@"+getProperty(ListNewHandsetDetailsConstant.PROP_OUTPUT_PATH_TWO_URL)+":"+getProperty(ListNewHandsetDetailsConstant.PROP_OUTPUT_PATH_TWO_JAR));
    Problem is this statement does not execute, as when I try it directly on command line, it requests for a password. Any suggestions on how I can get rid of that? I think I might have to configure my ssh_config file, but when I did some "Googling", I found the configuration settings of a ssh2_config file. I tried those (changing it to Host-based Authentication), but it didn't recognise them. Please help, this is so urgent!
    Regards,

    Don't use Runtime.exec (or ProcessBuilder) for this. Check out JSch at JCraft (or some other Java SSH API.

  • IOException File not found - While using Runtime.exec

    Hey All,
    I have written a Java application which needs to start up another external application. I have executables for that external application for different platforms (Win32, PPC and Linux). When the Java application is started it detects the OS and starts up the right executable according to the OS. The executable loads up fine on Windows without any problems. But in both Linux and Max OS X I get this exception:
    java.io.IOException: java.io.IOException: "/home/vilas/Documents/Project/build/CLISP/linux/lisp.run": not found

If I copy the string (/home/vilas/Documents/Project/build/CLISP/linux/lisp.run) and paste it in a terminal and press enter, the application starts up fine without any problems!! Can you please tell me what could be going wrong?
    The following extra information maybe helpfull:
    1) I use the exec(String command, String[] envp, File dir) version of exec.
    2) The complete format of the command is as follows (one long string):
    "/home/vilas/Documents/Project/build/CLISP/linux/lisp.run" -B "/home/vilas/Documents/Project/build/CLISP/linux" -M "/home/vilas/Documents/Project/build/CLISP/linux/lispinit.mem" -i loader.lisp
    Thanks in advance for your time and efforts.

    I found the problem after extensively searing the forums (looking upto page 4 !! of the results). The problem was that I was using quotes to surround the paths in the command. If you copy and paste it in a terminal it will work fine but it does not work with runtime.exec. I am not sure, but I think the reason is that when a terminal is used, some pre-processing of the commands take place before they are passed onto the OS(shell). But while using runtime.exec, that pre-processing is not peformed and therefore some things will not work.
    In order to fix the problem, I use quotes only when the OS is windows. In other cases(OS X, Linux) I escape the spaces i.e. replace " " with "\ ".
    PS: The executable is a binary compiled from C code.

  • Problem with Runtime.exec()

    Hi,
    I'm having a problem with Runtime.exec() . I have a batch file with debug option to FTP the desktop file to mainframe. When I executed this in Windows it's shows me the responce from the server (like ' Transfer Completed' ) for my FTP commands. But when I launch this through java it's only shows the errors not the normal responces from the server. I need this responses to confirm the proper transfer of file.
    My Java Code:
    String strCommand = "cmd.exe /c " + outdirectory + batchfilename;
    boolean bWait = true;
    Runtime r = Runtime.getRuntime();
    Process pr = r.exec(strCommand);
    BufferedInputStream bis =new BufferedInputStream(pr.getInputStream ());
    int c=0;
    /** Outlet for IO for the process **/
    while (c!=-1) {
    c=bis.read();
    /**Now wait for the process to get finished **/
    if(bWait == true){
    pr.waitFor();
    pr.destroy();
    My Batch file is :
    FTP -n -d -s:C:\IT2.cmd > C:\tIT2.log
    EXIT
    Thanks
    Sathiesh

    Ahh, you are redirecting the standard out from the ftp command to a file, therefore no output is sendt back to your java code,
    you have to redirect the stderr stream, not the stdout stream in your batch file;
    FTP -n -d -s:C:\IT2.cmd 2> C:\tIT2.log(notice the "2>" instead of ">")
    Now your batch file should direct the error stream to the log, and the standard output back to the java program.
    (I'm used to UNIX streams, not NT, but the "2>" redirection should work on NT also I guess)

  • Executing bat file without using Runtime.exec()??

    Hi all
    From my java App ,I am running a bat file. This is what I did:
    When I press 'execute' button inside my App, it runs a bat file through Runtime.exec() method. Since exec() runs it through cmd.exe, get a DOS window when I press Execute button. If I manually runs my app from command promt , I dont get it. But I have to create a short cut of my main class in the desktop. This is happening when I run my app from desktop icon.
    Now I want to eleminate DOS popup everytime I press execute button. Would anyone pls give an idea how to run bat file without using Runtime.exec()? Any suggestion will be helpful.
    Thanks

    jscell
    Thanks for taking time to answer to my problem .
    Here is what my problem: I create a shortcut of my main class in the desktop. Through this shortcut ,I run my java App. My App has a execute button, When I press this button , It run another bat file through Runtime.exec() method, and show some result in the result PAnel. NOw what happen , I get a DOS command window , everytime I press execute button. , Which is very annoying . But If I run my App thorugh command promt by executing: "java myApp", then I dont get this DOS popup. But I have to create a shortcut in the desktop, so other can use it conveniently.
    NOw I am not sure why I am getting this DOS window in the middle of my Application. IS it for using Runtime.exec() method? or for running bat file through my application? Can anyone pls tell me? I am kind of new to java, and I am learning lot of stuff from this forum .
    Would u pls suggest me about how to eleminate this DOS popup when I press execute button.

  • Any problem with Runtime.exec()

    I am required to launch a local exe from an applet. At present I am using AppletContext.showDocument().The problem with this is that in netscape a box is popped up forcing the user to save that exe file. The requirwment is to run it directly without any message being asked.
    A workaround is to use Runtime.exec(), it works, however I have heard that it is not platform independent.
    (1) Is there a better solution than Runtime.exec() ?
    (2) If not could you give me some info on Runtime.exec() and the problems associated with it ?
    (3) Is there a way to use AppletContext.showDocument() without the message being asked ?
    Shikari.

    First of all, Java is platform independent language, and has many security restriction in it's applets.
    so from an applet you can't excute a program using "Runtime.getRuntime().exec()".
    coz. there is security restriction on that.
    for the "AppletContext.showDocument()" this methid is for displaying the specified document on the client browser, so it can't excute a client program.
    if u need to use Runtime.getRuntime().exec() you have to get the client agreement for that.
    see the applet security restriction for more info.

Maybe you are looking for
