Intermittent Error with Runtime.exec()

I have a Windows Service for an Adaptive Server Anywhere database server that is built upon install of our application.
One of the new things we're trying to do with our app
requires us to shutdown this service using Java (1.4.2_06) code. This
shutdown is done by using the runtime.exec("dbsvc -x
ASA_SERVICE") command. Sometimes this works fine, but
others it fails. I got the error output from the java
command which is: Overlapped I/O operation is in progress.
Error stopping service "ASA_SERVICE". When I try and
shutdown the service via the Windows Service dialog I have
no problems anytime. I see no errors in the ASA log
file. Can someone tell me what might be
causing the error sometimes when running this using the Java
runtime.exec(...) command?
Thanks,
Cory Musselman

Try running the command a couple of dozen times from the command line, not from Runtime.exec() but just from a plain old command line. That should give you a better idea of whether Runtime.exec() is part of the problem or not.

  • 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)

    Hi Rangnath,
    For running SharePoint Designer 2013, you need to install Microsoft .NET 4.0 Framework or higher.
    Please uninstall the Microsoft .NET 4.0 Framework, and install it again. After that, reboot your machine.

  • Launch Acrobat Reader with Runtime.exec() under WINNT4, without absolut pat

    Hi,
    I would like to launch Acrobat Reader from a Swing application. This works fine with Runtime.exec() as long as I provide the full path to the AcroRd32.exe. The problem is that I cannot predict the location of this exe on the systems of the users. Athough is in the Windows PATH, since I can launch from the windows execute-dialog, the Runtime.exec() is not able to locate the file.
    How can I solve this problem?
    Thanks a lot!

  • Killing Internet Browser opened with Runtime.exec

    I am running Win NT 4.0 and I am successfully opening my HTML help using the following code:
    String command = new String("cmd /K ");
    command = command.concat("G:\editor\help\index.html");
    Process p = Runtime.getRuntime().exec(command);
    However, if I run p.destroy(), the browser window does not close. This means that the help remains open after the program exits and also that multiple help windows can be opened.
    Does anyone know how to kill a browser opened with Runtime.exec()?
    Thanks for any help you can offer,
    Christopher Collins
    Marineering Limited

    Thanks jmschrei,
    I tried System.exit(0) and Runtime.getRuntime().exit(0) and neither succeeded in closing the internet browser process. I suspect that process.destroy() and runtime.exit(0) both are killing the instance of the command interpreter spawned by runtime.exec("cmd /K URL") and not actually the browser opened by that command. Therefore, I think that the process refers to the "cmd" and not the browser, which probably opens completely independently of my Java program, thus can't be closed by it.
    Unforetunately, I don't know another way to open a browser.
    If anyone has any additional suggestions, I would appreciate it. Many people in the forums seem to have asked this one, and there are no solutions I could find.

  • Intermittent errors with mxmlc

    Hi All,
    I have recently begun to encounter intermittent errors when executing the mxmlc ant task.  This appears to be some sort of timing issue, because I can just re-run the task and have the build run to completion.  The errors that I get vary, but usually are either invalid implicit coercions (with a line number being reported of -1), or attempting to access fields or functions that don't exist (with an actual line number where the error supposedly occurs).  In each of these case, I get many errors, followed by a ton of invalid embed commands.
    As I mentioned before, simply re-running the task will either cause a successful compilation, or a completely different set of errors and line numbers being reported.  This is turning into a very high visibility issue because automated builds are failing, and the only thing that I can do is to tell them to run it again.
    Here is the list of options that I'm sending to mxmlc:
    static-link-runtime-shared-libraries=true
    debug=false
    keep-generated-actionscript=false (have changed to true in an attempt to find the problem)
    incremental=false
    We are using the 4.5.1 "full" SDK, ant 1.8.2, and JDK 1.6.0_30.
    Thank you for any help or insight!

  • Problems with Runtime.exec inside OC4J in OAS!!! help!!

    Hi all,
    I have a method on my webapplication and the same call a script .cmd on windows and a .sh on unix using Runtime.exec command, inside this script have a call to a java program ie.
    java JMSAdmin < jcajms.txt
    OK, this is fine in OC4J Standalone 10.1.3 in windows and linux but in OAS 10.1.3 the same not run and not throw any error. Its is a BUG ?? limitation ?? OAS ignore a call to another java ??
    please help.
    Tanks

    Normally, you must prepend the command with a call to the command shell (eg /bin/sh).
    But I suspect that this call isn't allowed due to Java EE specification restrictions.

    Why are you posting hundreds of lines of code not related to the problem??? 99.9% of the code you posted has absolutely nothing to do with using the Runtime.exec() method.
    Create a simple test program that simply tries to invoke the Runtime.exec() method. Once you get that working, then you incoporate it into you real program. Don't clutter the forum with unnecessary code.
    public class WindowsFileProtocolHandler
         public static void main(String[] args)
              throws Exception
              String[] cmd = new String[4];
              cmd[0] = "cmd.exe";
              cmd[1] = "/C";
              cmd[2] = "java";
              cmd[3] = "YourClassHere";
              Process process = Runtime.getRuntime().exec( cmd );

  • Executing .cmd with Runtime.exec()

    I'm trying to run a file with the following cod:
    Runtime rt = Runtime.getRuntime();
    String[] command = {"cmd.exe", "/c", "start", "c:\\Documents and Settings\\Rahul Shroff\\Desktop\\svn\\trunk\\c\\rahul_facedetect.cmd"};
    try{
             Process proc = rt.exec(command);
    catch(Exception e) {System.out.println("error with proc" + e.getMessage());}With the code, a command prompt is opened, but my .cmd file is not. Does anyone know how to fix this? Please don't send me a link to the "When Runtime.exe() Won't" ; I have already looked through this. Thanks!

    Okay, I tried that, and the code compiled fine, but I got this runtime error:
    error with procCreateProcess: "C:\Documents and Settings..." error = 123
    My code is :
    Runtime rt = Runtime.getRuntime();
        String[] command = {"C:\\Documents and Settings\\Rahul Shroff\\Desktop\\svn\\trunk\\c\\rahul_facedetect.exe --cascade=C:\\Documents and Settings\\Rahul Shroff\\Desktop\\svn\\trunk\\OpenCV\\data\\haarcascades\\haarcascade_frontalface_alt.xml"};
        try{

             System.out.println("tried to execute .cmd");
        catch(Exception e) {System.out.println("error with proc" + e.getMessage());}
      }I am sure that the command C:\Documents and Settings... works; I've tried it separately in a command prompt. Any suggestions? Thanks for the help!

  • I am getting intermittent error messages "Runtime Error" when clicking on links

  • Launch Command Line Scanner with Runtime.exec()

    Hi im trying to develop all the process of a common Antivirus ,
    I have a command line anti-virus. But when i try to scan a single file mi code doesnt work.
    I made the following code:
    Runtime runtime = Runtime.getRuntime();
    commands = new String[] {"cmd.exe", "/c","C:\\KAVCLineScanner\\kavecscan.exe","C:\\anfed\\a.txt"};
    Process p =runtime.exec(commands);
    BufferedReader b =new BufferedReader(new
    InputStreamReader(p.getInputStream()));
    String line=null;
    while( (line=b.readLine())!=null){
    System.out.println(line);
    I think the problem is my parameter where i send the file to scan "C:\\anfed\\a.txt", because if i execute this instruction from MSDOS, the process doesnt have problems.
    I also made a .bat file with the instructions but i have the same problem :(
    Thanks for any advise

    I think java naming is from programmer's point of view, so the output stream of the process would be the inputstream to the programmer, hence I am trying to write to my outputstream, which is actually the process' inputstream.

  • Problems with Runtime.exec() and certain Unix processes

    Certain Unix processes don't behave correctly when run from Java using Runtime.exec(). This can be seen by running /bin/sh and trying to interact with it interactively. The issue appears to be that /bin/sh (and many other Unix tools) are checking the file handles on the spawned process to see if they are associated with a TTY.
    Is there any way to associate a process spawned by Runtime.exec() with a terminal or alternatively, is there a JNI library available that would setup the process correctly and still provide access to the input and output streams?
    Our objective is to have the flexibility of expect in being able to run and interact with spawned processes. A bug was opened at one point but closed back in 1997 as being a fault in the spawned process, not Java.

    }This program reopens its standard input against /dev/tty and catenates it to stdout. And voila, it takes its standard input from the terminal, even though it was started with stdin against /dev/null..
