Error while running DOS command in Java

Hi all,
I use "runtime" class to execute a DOS command "copy C:\\pathname\\*.* C:\\backupPathname\\". But I saw an error msg "CreateProcess: copy C:\pathname\*.* C:\backupPathname\ error=2".
I did create a folder C:\backupPathname\ before running the DOS command.
Pls help me all Java genius.

I ended up writing a small 'c' program and pasing the command in to it from java. The problem seems to be that in dos, unlike unix, the copy command is not a program, rather the command is interpreted by the command.com program.

Problem while running dos command from java program

Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
     public static void main(String args[]) {
          KillProcess kProcess = new KillProcess();
          kProcess.getRunningProcess();
          kProcess = new KillProcess();
          kProcess.readProcessFile();
     public void getRunningProcess() {
          String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
          try {
               Runtime run = Runtime.getRuntime();
               Process process = run.exec(cmd);
               int i = process.waitFor();
               String s = null;
               if(i==0) {
                    BufferedReader stdInput = new BufferedReader(new
                           InputStreamReader(process.getInputStream()));
                    while ((s = stdInput.readLine()) != null) {
                     System.out.println("--> "+s);
               } else {
                    BufferedReader stdError = new BufferedReader(new
                           InputStreamReader(process.getErrorStream()));
                    while ((s = stdError.readLine()) != null) {
                     System.out.println("====> "+ s);
               System.out.println("Running process End....");
          } catch(Exception e) {
               e.printStackTrace();
     public String readProcessFile() {
          System.out.println("Read Process File...");
          File file = null;
          FileInputStream fis = null;
          BufferedReader br = null;
          String pixieLoc = "";
          try {
               file = new File("ProcessList.txt");
               if (file.exists() && file.length() > 0) {
                    fis = new FileInputStream(file);
                    br = new BufferedReader(new InputStreamReader(fis, "UTF-16"));
                    String line;
                    while((line = br.readLine()) != null) {
                         System.out.println(line);
               } else {
                    System.out.println("No such file");
          } catch (Exception e) {
               e.printStackTrace();
          return pixieLoc;
}     when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,
Sathish

}when i execute the above code, i got output as,
Execing cmd.exe /C wmic process where "name='java.exe'" get commandline,processid
and keeps in running mode only.
If i execute the same command in dos prompt,
CommandLine
ProcessId
java -classpath ./../lib/StartApp.jar;./../lib; com.abc.middle.startapp.StartAPP 2468
If i modify the command as,
cmd.exe /C wmic process where "name='java.exe'" get commandline,processid > 123.txt
and keeps in running mode only.
If i open the file when program in running mode, no contents in that file.
If i terminte the program and if i open the file, then i find the processid in that file.
Can you help me to solve this issue?

How to run DOS command in Java environment?

Can i run DOS command in Java environment?
I did like this:
Runtime r = Runtime.getRuntime();
r.exec("cmd.exe");
r.exec("set classpath=%CLASSPATH%;.\\tmp")
but failed.
However if I run the java command, it runs successfully.
r.exec("javac Test.java");
r.exec("java Test");
how should I do so that i can run the DOS commands metioned above in Java Environment?
thanks a lot.

Have a look at http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
This may help. I wonder if this is ok ?
Runtime r= Runtime.getRuntime();
r.exec("cmd.exe /C set classpath=%CLASSPATH%;.\\tmp\"");

Running DOS command from JAVA

Hi ,
I would appreciate if anyone could tell me how to run DOS command such as "del" using JAVA language .Thank you.

<steps onto soapbox>
Surely for something like 'del' we should be advocating a non-OS specific method so we don't lose sight of Java's cross platform abilities.
If it has to run an OS specific thing fine, but please look for a non OS specific solution first.

Run dos command from java

May I ask how I should write if I want to execute a dos command in java? The command is :
"C:\Program Files\Real\realproducer\rmeditor -i abc.rm -d abc.txt". Should I use array?
Thanks!

why an array ?
String command = "C:\\Program Files\\Real\\realproducer\\rmeditor -i abc.rm -d abc.txt";
Process p = Runtime.getRuntime().exec( command );what about the seach function on the left side ? ;-)

Error while running the SAP JCO java program running via command line

Hi,
We are facing an issue while using SAP JCO. When i try to run the sample program using RAD 8.0 ( IBM IDE tool For Java Development) its working fine.
The same sample program if i try to run using command line, Then its giving below exception message.
Exception in thread "main" java.lang.NoClassDefFoundError: Integration
NOTE: I have configured proper sapjco jar & Dll files path in class path settings in my batch file.

Hi,
class loader can't find class definition during runtime but it could find it during compilation. So the problem is with your classpath. Does your classpath point to file with class Integration? Check this [blog|http://javarevisited.blogspot.com.au/2011/06/noclassdeffounderror-exception-in.html].

Error while running executable file through java in WinNT

I would like to run an executable file with Java.
- If I try with notepad or paint, i.e. Windows Applications,
  I have no problem.
- I also can run Non-Windows-Own Applications, except one.
  I get an error message, if I want to run this program through Java.
I have tried following commands to run an executable file.
Runtime.getRuntime().exec("cmd.exe /c "+command);
Runtime.getRuntime().exec("cmd.exe /c start "+command);
Runtime.getRuntime().exec("cmd.exe /c start /wait "+command);
Runtime.getRuntime().exec("cmd.exe /k start "+command);
command : the path to the executable file
I can run the application directly, if I click the icon on desktop,
but not through Java.
here is the error message I get
screenshot : http://www.aykut.de/error_message.jpg
Text : "Security Check failure"
        The Logon System has been tampered with.
        The Administrator will need to re-install.
my Idea :
The application is "old".
I think it was written for Win 3.1.
Therefore I don't know if there is any other
possibilty to run a "DOS Exe File" through Java.

I have just figured out how it works,
if somebody else here in forum have this problem,
here is the solution :
String path = "F:\...\...\Application.exe";
String envDir = path.substring(0, path.lastIndexOf("\\"));
String[] command = {"cmd.exe", "/c", "start", "/wait", "/D"+envDir, path};
Process process = Runtime.getRuntime().exec(command);
"start /Dpath" => path: environment directory F:\...\...\
"start /wait" => wait until Application.exe terminates
if you use Win95 or Win98 use command.com instead of cmd.exe

HOW DO I RUN DOS COMMANDS ON JAVA

I SWEAR, I'LL PAY YA IF YOU HELP ME!!!
Hi, this is the thing:
have you ever run the "time" command on a DOS console?? if you have, you know that it shows the current time, and lets you set a new time.
well, i need to make a java program to open a DOS console and execute the command, and making it able to write in information on the console so it sets a new time.
MY PURPOSE IS NOT JUST WATCHING THE CURRENT TIME!! so please don't tell me to use System.getCurrentTimeMillis() or something like that; i explicitly need to run that DOS command. what's the Java code to do it??
thank you!! and please attach your account # so you get a $50 deposit by the end of the week
thank you!!

Thanks a lot, you all guys, but i don't know what's with this thing.... it always throws an IOException, with the following exception stack trace:
java.io.IOException: CreateProcess: temp.bat error=0
        at java.lang.Win32Process.create(Native Method)
        at java.lang.Win32Process.<init>(Win32Process.java:63)
        at java.lang.Runtime.execInternal(Native Method)
        at java.lang.Runtime.exec(Runtime.java:550)
        at java.lang.Runtime.exec(Runtime.java:416)
        at java.lang.Runtime.exec(Runtime.java:358)
        at java.lang.Runtime.exec(Runtime.java:322)
        at Tarea.main(Tarea.java:15)and it will come out the same shit over and over. The above case was thrown by the line Runtime.getRuntime().exec("temp.bat") where temp.bat is a file where the only thing written in it is the word "time". and you can change the string parameter of the method exec, and thats what will change in the stack trace above.
I also tried "cmd", "command", and "command.com". With the last one, it opens the command.com application but it freezes and does nothing. With the other two, appears the same old shit from above.
Please help me!!
Thank you...

We ran into this, too. It was filed as a bug and will be fixed in the PS1 release (11.1.2.1). Oracle wouldn't commit to a release date tho. As this is core functionality, it would be good if you raised it with Oracle support. This will make it easier to lobby for a patch.

Running Dos command in Java

hey, Just wondering can anyone help me get started, i pretty new to java and wanted to run the date command in Dos from a java application. If i could just know where to begin or even if this is possible, it would be much appreciated!!

If you're using Runtime.exec() you need to read this:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
If you're new to java it might be a bit heavy, but definitely add it to your "Favourites" for later!
