Run executabeles in a java program

I am running windows platform...I was wondering if there is a java package that would allow me to run an executable file from within a java program? ...in other words, is there a method i could call that would ,for example, take a .exe file reference parameter and run that exe file in a seperate process (much similar to what would happen when say double clicking an application program)?

Hi,
U Can Try This Option As Well...
Process prc = Runtime.getRuntime().exec("Exe File Name");

How to run Perl script in Java program?

Some say that the following statement can run Perl script in Java program:
Runtime.getRuntime().exec("C:\\runPerl.pl");
But when I run it, it'll throw IOException:
java.io.IOException: CreateProcess: C:\runPerl.pl error=193
at java.lang.Win32Process.create(Native Method)

Exception in thread "main"
Where is the problem? In fact, I do have a Perl script named "runPerl.pl" in my C:/ directory. Could anybody tell me why it can't be run? Thanks in advance.

Hello sabre,
First of all thanks for your reply.
I have tried like what you mentioned.
Eventhough, i could get the exact error message.
I could get the Exception
"Exception:java.lang.IllegalThreadStateException: process hasn't exited"
<code>
import java.io.*;
public class Sample{
public static void main(String args[]) {
String s = null;
Process p;
try
     p = Runtime.getRuntime().exec("tar -vf sample.tar");
     //p.waitFor();
     if(p.exitValue() == 0)
          System.out.println("CommandSuccessful");
     else
          System.out.println("CommandFailure");
catch(Exception ex)
     System.out.println("Exception:"+ex.toString());
</code>
In this code, i tried to run the "tar command". In this command i have given -vf instead -xvf.
But it is throwing
"Error opening message catalog 'Logging.cat': No such file or directory
Exception:java.lang.IllegalThreadStateException: process hasn't exited
CommandFailure"
"Error opening message catalog 'Logging.cat'" what this line means ie,
I dont know what is Logging.cat could you explain me its urgent.
Thanks in advance.

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,

Please help How can i run Os commands thru Java programs

Hey,
I want to stop and restart the linux server thru java program.Is it possible to run the os commands thru java program.
I had it thru Runtime.getRuntime().exec("*.exe");
it only runs the exe files.How can run files other than exe files like .bat,com ans shell commands..Any body knows please help with the code..or mail to this address
[email protected]
thankyou,
regards,
j.mouli

What about "start command.com /C execute.bat", or using the overload that takes a String[] as argument?
What if you use the the full path of execute.bat?
What error code do you get?
And what comes th linux, I'm not sure... you'll need a shell interpreter there too, me thinks. (never had to run anything with runtime.exec on linux). Check the man pages if csh, bash, ksh, or what ever shell you like.

How to run sscript shell with java program

Hi everybody,
i want to know how can i do to execute a script shelle (bash) with program java (if it s possible)
for example this script:
#!/bin/bash
echo "hello"
can i run it with java program or i have to make dome modifications .
thank you for your help in advance.

Well, if you want to be portable across platforms, you should write as much code in Java as possible and not rely on native scripts (I'm sure your script is more complex than this 'echo' example ;-) ).
Having said that, you can use the java.lang.Runtime class and in particular its various exec() methods.
Try something like this:
Process p;
try {
p = Runtime.getRuntime().exec("myscript.sh");
} catch (IOException ioe) {
}You can then "interact" with the spawned process with the Process object returned by the exec method.
Note you need to have the appropriate security rights.
For more details, look at the API documentation here:

Hi!
What do you mean execute commands? Like: "openssl x509 -in cert.pem -out certout.pem" ??
In that case you can just try the following:

Error when running a very simple java program

java.lang.NoClassDefFoundError: HelloWorldApp
Exception in thread "main"
Tool completed successfully
I am getting the above error. I just downloaded java standard edition 1.4 sdk. I compiled the program with no errors. But when I run it . I get the above error. Is it something related to finding the package java.lang?
Please let me know.
Thanks.

I have the same problem but in a different way. I download/installed jdk1.4 and J2me. I was able to run j2me without any problem following their tutorial.
I set my config.sys to:
PATH=C:\j2sdk1.4.0\bin;C:\j2me\j2me_cldc\bin;C:\j2me\midp1.0.3fcs\bin;
I did compile and ran couple of programs with no problems at all, for some reason some of them give me error ex: Exception in thread "main" java.lang.NoClassDefFoundError: NamofFile
I read couple of posting about setting the CLASSPATH, is that maybe the source of the problem if so how I can do so given that I�m using win2000. Any Ideas !!!

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].

Run shell commands using java program

Hi guys,
I am trying to run shell commands like cd /something and ./command with arguments as follows, but getting an exception that ./command not found.Instead of changing directory using "cd" command I am passing directory as an argument in rt,exec().
String []cmd={"./command","arg1", "arg2", "arg3"};
File file= new File("/path");
try{
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(cmd,null,file);
proc.waitFor();
System.out.println(proc.exitValue())
BufferedReader buf = new BufferedReader(new InputStreamReader(proc.getInputStream()));
catch(Exception e)
{e.printStackTrace();
So can anyone please tell me what is wrong with this approach? or is there any better way to do this?
Thanks,

What gives you the idea that the process to execute is called "./command"? If this is in Windows, it is "cmd.exe" for example.It does not have to be cmd.exe in Windows. Any executable or .bat file can be executed as long as one either specifies the full path or the executable is in a directory that is in the PATH.
On *nix the file has to have the executable bit set and one either specifies the full path or the executable must be in a directory that is in the PATH . If the executable is a script then if there is a hash-bang (#!) at the start of the first line then the rest of the line is taken as the interpreter to use. For example #!/bin/bash or #!/usr/bin/perl .
One both window and *nix one can exec() an interpreter directly and then pass the commands into the process stdin. The advantage of doing this is that one can change the environment in one line and it remains in effect for subsequent line. A simple example of this for bash on Linux is
import java.io.OutputStreamWriter;
import java.io.Writer;
public class ExecInputThroughStdin
    public static void main(String args[]) throws Exception
        final Process process = Runtime.getRuntime().exec("bash");
        new Thread(new PipeInputStreamToOutputStreamRunnable(process.getErrorStream(), System.err)).start();
        new Thread(new PipeInputStreamToOutputStreamRunnable(process.getInputStream(), System.out)).start();
        final Writer stdin = new OutputStreamWriter(process.getOutputStream());
        stdin.write("xemacs&\n");
        stdin.write("cd ~/work\n");
        stdin.write("dir\n");
        stdin.write("ls\n");
        stdin.write("gobbldygook\n"); // Forces output to stderr
        stdin.write("echo $PATH\n");
        stdin.write("pwd\n");
        stdin.write("df -k\n");
        stdin.write("ifconfig\n");
        stdin.write("echo $CWD\n");
        stdin.write("dir\n");
        stdin.write("cd ~/work/jlib\n");
        stdin.write("dir\n");
        stdin.write("cat /etc/bash.bashrc\n");
        stdin.close();
        final int exitVal = process.waitFor();
        System.out.println("Exit value: " + exitVal);
}One can use the same approach with Windows using cmd.exe but then one must be aware of the syntactic differences between commands running in .bat file and command run from the command line. Reading 'help cmd' s essential here.
The class PipeInputStreamToOutputStreamRunnable in the above example just copies an InputStream to an OutputStream and I use
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
public class PipeInputStreamToOutputStreamRunnable implements Runnable
    public PipeInputStreamToOutputStreamRunnable(InputStream is, OutputStream os)
        is_ = is;
        os_ = os;
    public void run()
        try
            final byte[] buffer = new byte[1024];
            for (int count = 0; (count = is_.read(buffer)) >= 0;)
                os_.write(buffer, 0, count);
        } catch (IOException e)
            e.printStackTrace();
    private final InputStream is_;
    private final OutputStream os_;

Running Tomcat from a java program

I'm writing a program that shall run Tomcat from the program itself. The eacy way would be to just call org.apache.catalina.startup.Bootstrap.main(String[]) in a new thread, but that gives only a little information to the program about the state of the server. Actually I would only know when the server is told to start (just before the main method is called), and when the server had stopped (just after the main method).
I have browsed the Catalina API documentation and source code for hours, but the only solution I have gotten, writes the standard startup text:
Starting service Tomcat-Standalone
Apache Tomcat/4.0.4
Starting service Tomcat-Apache
Apache Tomcat/4.0.4If I could get that to work, I would could add a LifecycleListener, and get all the info. I need.
The essence of the code I use is this:
CatalinaService cs = new org.apache.catalina.startup.CatalinaService();
Server s = new StandardServer();
StandardService stdService = new org.apache.catalina.core.StandardService();
s.addService(stdService);
cs.setServer(s);
cs.process(new String[]{"start"});but the following also produce a simmilar result:
BootstrapService b = new org.apache.catalina.startup.BootstrapService();
b.load(new TomcatLoader(),null);
b.start();A dirty solution would be to copy the code form Bootstrap.main(String[]) and add a few lines, but I really dosn't like that. It would be a nightmare to maintain, primiarry because I would loose the functionallity of Catalinas class loader (where a lof of classes is loaded).
Does anybody know how I can get Tomcat to run, so I still get my info. and don't use any dirty solutions?

Check out the main method in the source code of class org.apache.catalina.startup.Embedded
It should help you.

Running ssh from within java program

Hi!
I am trying to start ssh from within java e.g.:
Runtime run = Runtime.getRuntime();
Process pro = run.exec("ssh -l xx 12.12.12.12");
But it complains:
socket: Operation not permitted
ssh: connect to host 12.12.12.12 port 22: Operation not permitted
Running ssh from the command prompt works just fine. It's run on win xp.
What is the problem, and how can I avoid it?

Afraid not. I think maybe it's related to security permissions, but I am really not sure. If you can help, I would appreciate it.

Problem with running java program

Hey again!
I missed out some information in last posting.. here is the full description
I have just installed 1.5.0_06 and have set paths and what otherwise is necessary to run the java programs. I was testing the install and run a standard HelloWorld.java program
I got the following error:
Exception in thread main java.lang.NoClassDefFoundError: HelloWorld
what is wrong...
Here is the entire HelloWorld.java
public class HelloWorld
public HelloWorld()
System.out.println("Hello World");
public static void main(String[] args)
HelloWorld hw = new HelloWorld();
I have checked that the path is correct too..
Hopefully someone can help me!
Anders

Your Path is set, probably the problem is classpath.
Change the cmd/command prompt to the directory that contains your HelloWorld.class file, verifying that it exists. If it does, issue this command from that directory:
java -cp . HelloWorld
Important: include the period and surrounding spaces
If that works, you can learn about setting and using the classpath here:
http://java.sun.com/j2se/1.5.0/docs/tooldocs/index.html#general
By the way, just add a reply to your original post with the additional information, rather than creating another post. That eliminates duplication of replies.
