Running jar in unix using runtime exec command

Hi, i want to run a jar in unix with the runtime.exec() command,
but i couldn't manage to do it
Here is the code
dene = new String[] {"command","pwd","java tr.com.meteksan.pdocs.pdf.html2pdf "+ f.getAbsolutePath() + " " + pdfPath};
          System.out.println("Creating PDF");
          FileOutputStream fos = new FileOutputStream(new File(pdfPath));
          Runtime rt = Runtime.getRuntime();
          for(int i = 0 ; i < dene.length ; i++)
              System.out.println("komut = "+dene);
          Process proc = rt.exec(dene);
          // any error message?
          StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR"); // any output?
          StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT", fos); // kick them off
          errorGobbler.start();
          outputGobbler.start();
          // any error???
          int exitVal = proc.waitFor();
          System.out.println("ExitValue: " + exitVal);
          fos.flush();
          fos.close();
when i run this program, the exit value of the process is 0
can you tell me whats wrong?

i changed the string to be executed to:
                         dene = new String[] {"sh","-c","java -classpath \"" + Sabit.PDF_TOOL_PATH

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.

??First of all, you're not even calling the Happy Holiday one. If you want it to do something, you have to invoke it.
And by the way, in your comments, you mention that in one case, a new process is created. Actually, new processes are created each time you call Runtime.exec.
Anyway, if you want the output from the processes, you read it using getInputStream from the Process class. In fact, you really should read that stream anyway (read that URL I sent you to find out why).
If you want to print that output to the screen, then do so as you'd print anything to the screen.
in notepad HelloWorld.java, I can see it is opened,
but in Java, not.I have no idea what you're saying here. It's not relevant whether a source code file is opened in Notepad, when running a program.

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.

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.
As an aside, despite being opposite ends of the one question, I do not consider this question to be 'part' of the current thread. I think you would have been better off starting a dedicated thread and explaining more fully what the use case is (and adding lots of Dukes).

How to run db2 command by using Runtime exec

Hello
I am using java. When i am runing db2 command by using Runtime.exec( String cmd, String[] env ). I gave the environment path
DB2CLP=6259901
DB2DRIVER=D:\ibm\db2\java\db2java.zip
DB2HOME=D:\ibm\db2
DB2INSTANCE=DB2
DB2MMTOP=D:\CMBISS
but still I am getting error message
"DB21061E Command line environment not initialized"
after setting the above path in the cmd It is working fine. When i am trying thro java programm i am getting the above error. Can I get answer for this.
bhaski.

Before you can execute DB2 commands you have to open a DB2 CLP. The following code will do so:
import java.io.IOException;
public class Db2 {
     public static void main(String args[]) {
          try {
               Runtime rt = Runtime.getRuntime();
               Process child = rt.exec("db2cmd");
               child.waitFor();
          catch (IOException io) {
               io.printStackTrace();
          catch (InterruptedException e) {
               e.printStackTrace();

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:

            StreamThread(InputStream is, String type)
                this.is = is;
                this.type = type;
            public void run()
                try
                    InputStreamReader isr = new InputStreamReader(is); //never gets called
                    BufferedReader br = new BufferedReader(isr);
                    String line=null;
                    while ( (line = br.readLine()) != null)
                        System.out.println(type +">"+ line);
                    } catch (IOException ioe)
                        ioe.printStackTrace();
        try {

                  "./fortranCodeName" , null, new File("/home/myRunDir/"));
            StreamThread stream = new StreamThread(process.getInputStream(), "OUTPUT");
            StreamThread errorStream = new StreamThread(process.getInputStream(), "ERROR");
            stream.start();
            errorStream.start();

Using Runtime.exec on a Unix System

hi,
I have a web service which executes a command line process 'Runtime.exec(command)'. When the server starts to go on a high load I start to get "IOException: Not Enough Space" which I understand means that I am running out of swap space. No problem as I can increase the swap space to cope with demand. The problem is that I have read that when JVM attempts a fork on a Unix system it temporarily creates a new JVM with the same space requirements as the app server JVM. So if I set my app server to require 1GB memory, I am likely to need to set up swap so that it has 1GB * Number of Parallel Processes. I need to know if this is correct. Our application today does not limit the number of Runtime.exec commands which can be run in parallel and if the above is true we are going to have a problem ensuring we don't run out of memory.
Can any one verify this or suggest other solutions to the problem?
Thanks
Stephen

hi,
Yes, very helpful jwenting! Problem is that we are working with legacy systems where we have few other options. If you can give any positive input it's not worth leaving your option at all.
Thanks

PATH Setting using Runtime.exec() on a UNIX env?

Hi,
How do we set the PATH using Runtime.exec() on a UNIX Env?
I've tried the 'export' command and 'setenv' command but it throws an exception saying 'export' and 'setenv' not found.
objProcess = Runtime.getRuntime().exec("setenv PATH /opt/ibm/java2-x86_64-50/bin");+
Please suggest.
Thanks,
Tanu

Your experimenting with the stuff could shed light on the question, whether the outcome is influenced by the relying of the started process on elements of the starting environment other than PATH.
String[] envp=new String[1];
envp[0]="PATH=/jdk1.5/bin";
Runtime rt=Runtime.getRuntime();
Process proc=rt.exec("java Test",envp);

How to display Runtime.exec() command line output via swing

Hi all, I'm new to java but have a pretty good understanding of it. I'm just not familiar with all the different classes. I'm having trouble capturing the output from a command I'm running from my program. I'm using Runtime.exec(cmdarray) and I'm trying to display the output/results to a JFrame. Once I get the output to display in a JFrame, I'd like it to be almost like a java command prompt where I can type into it incase the command requires user interaction.
The command executes fine, but I just don't know how to get the results of the command when executed. The command is executed when I click a JButton, which I'd like to then open a JFrame, Popup window or something to display the command results while allowing user interaction.
Any examples would be appreciated.
Thank you for your help in advance and I apologize if I'm not clear.

You can get the standard output of the program with Process.getInputStream. (It's output from the process, but input to your program.)
This assumes of course that the program you're running is a console program that reads/writes to standard input/output.
In fact, you really should read from standard output and standard error from the process you start, even if you're not planning to use them. Read this:

Using runtime.exec to zip some files

Hi,
I am using runtime.exec to try to automatically zip a bunch of files on a server. However, it does not seem to be working.
Before I execute the command, I save the zip command in a string. I then print the string to a log file, and then execute the runtime zip command. But nothing happens.
Yet, when I copy the string from the log, and paste it in a terminal, it properly creates the zip files. So, I know I have the correct command string, it just does not seem to be working within the java application. Also, the command string uses fully qualified directories, so it is not a directory issue.
I am using ubuntu linux.
Any ideas?

Within Runtime.exec() any command does not run in a shell and I bet you use wild cards and/or other commands to be interpreted by a shell which will not be interpreted since there is no shell. And, since you don't mention error messages or the return code, I will also bet you don't process the Process stdout , stderr and the return code properly.
It looks to me like you have fallen for at least two for the traps in [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html].

}The inputStream of the process doesnt get printed at all , the loop condition in StreamGobbler 'while ( (line = br.readLine()) != null)
' is never true.
Also , in random cases i've seen the System.out.println("exitVAl "+exit); line executing before the System.out.println("Start Reading"); line , and i though proc.waitFor() would guarentee otherwise.

thx guys for ur replies . The issue was because of some browser security system ( or so they said . ).However i'm still puzzled about the 'waiting for the stream to finish' part .

Also, do not break out >>of the loop when you find what you're looking for, you should >>continue .reading until the end of the stream.Wasn't I suppose to be reading out of the stream to prevent an overflow?Also the break is done there are multiple lines like 'Physical address .....: xxxxxxxxxx ' in the output , and the macid is the first one.About the ProcessBuilder , I'll look into it . Thx for your advice.
