Run command prompt from java?

Question

Hi i want to run something from command prompt using java

i want to go to the following directory C:\Program Files\OpenOffice.org 3\program\ and then run soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

i tried but i am not able to do that!

my code

public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            Runtime rt = Runtime.getRuntime();
            //Process pr = rt.exec("cmd /c dir");

           // Process pr = rt.exec("cmd /c dir");

            Process pr = rt.exec(new String[]{"C:\\Program Files\\OpenOffice.org 3\\program\\soffice", 
                    "-headless",
                    "-accept='socket,host=127.0.0.1,port=8100;urp;'",
                    "-nofirststartwizard"});

            BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));

            String line=null;

            while((line=input.readLine()) != null) {
                System.out.println(line);
            }

            int exitVal = pr.waitFor();
            System.out.println("Exited with error code "+exitVal);

        } catch(Exception e) {
            System.out.println(e.toString());
            e.printStackTrace();
        }
    }

What sort of error are you getting? It's possible that soffice is not in you system path. — joekarl, Jun 08 '11 at 05:12
please post the *minimum complete* code that exhibits the problem behavior, and also post the stacktrace. — jcomeau_ictx, Jun 08 '11 at 05:12

Don't use cd, and use the string array method:

rt.exec(new String[]{"C:\\Program Files\\OpenOffice.org 3\\program\\soffice.exe", 
    "-headless",
    "-accept='socket,host=127.0.0.1,port=8100;urp;'",
    "-nofirststartwizard"});

can i first change the directory and then run "soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard" – Harinder Jun 08 '11 at 05:18
No you can't change the directory first – OscarRyz Jun 08 '11 at 05:23
@Harinder I updated the answer to include `.exe`, could you try again with this new line? By the way you can not and do not need to use `cd` here. – Thomas Mueller Jun 08 '11 at 06:58

Finally i solved it

String[] SOFFICE_CMD = { "C:/Program Files/OpenOffice.org 3/program/soffice", "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager", "-invisible", "-nologo"}; 
        Runtime.getRuntime().exec(SOFFICE_CMD);

Thank u all for supporting!!

@Harinder : I would like to suggest an alternative method. What u can do is ;

First try to run whatever u want to run from the command prompt directly with all attributes etc. Once u have successfully run the service/application from the command prompt directly do 2.
Go and save the command in a .bat file.

For example: C:\m-admin\app.exe I saved this as app.bat on C:\

Now modify ur java code accordingly to execute this script which will in turn execute ur application or service.

For example:

 ProcessBuilder builder = new ProcessBuilder(new String[]{"cmd", "/c","C:\\app.bat"});
 Process pr =   builder.start();
 BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));

if even this does not work ...we need to start from scratch again.

I have edited the code(below) using the process builder method. See if this works for you. Using exec sometimes does not work due to access violations:

public static void main(String[] args) {
    // TODO Auto-generated method stub
    try {
        Runtime rt = Runtime.getRuntime();
        //Process pr = rt.exec("cmd /c dir");

       // Process pr = rt.exec("cmd /c dir");
       ProcessBuilder builder = new ProcessBuilder(new String[]{"cmd", "/c", "C:\\Program Files\\OpenOffice.org 3\\program", "soffice",
        "-headless",
        "-accept='socket,host=127.0.0.1,port=8100;urp;'",
        "-nofirststartwizard"});
       Process pr =   builder.start();
       BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));


        String line=null;

        while((line=input.readLine()) != null) {
            System.out.println(line);
        }

        int exitVal = pr.waitFor();
        System.out.println("Exited with error code "+exitVal);

    } catch(Exception e) {
        System.out.println(e.toString());
        e.printStackTrace();
    }
}

}

i want C:\\Program Files\\OpenOffice.org 3\\program\\ to be my directory when i run soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard — Harinder, Jun 08 '11 at 05:31

I think I have found your mistake: change your argument to the following: See if it works:

(new String[]{"cmd", "/c", "C:\\Program Files\\OpenOffice.org 3\\program\\soffice",
            "-headless",
            "-accept='socket,host=127.0.0.1,port=8100;urp;'",
            "-nofirststartwizard"})

I think u was correct about changing the directory first. See the above code again...I made some edits to the original thing i posted... – knurdy Jun 08 '11 at 05:47
@Harinder : I am making my last effort, I have done some edits above...try this one for me... – knurdy Jun 08 '11 at 05:57
if i remove "cmd", "/c", and then run this i get Cannot run program "C:\Program Files\OpenOffice.org 3\program": CreateProcess error=5, Access is denied – Harinder Jun 08 '11 at 05:57
the following works for me: `new String[]{"cmd", "/c","C:\\m-admin\\app.exe"}` did u got it running?? if yes do post your solution – knurdy Jun 08 '11 at 06:11
@knurdy you forgot the `.exe` after `soffice` in your answer (well I did as well...) – Thomas Mueller Jun 08 '11 at 06:59
even ProcessBuilder builder = new ProcessBuilder(new String[]{"cmd", "/c", "C:\\Program Files\\OpenOffice.org 3\\program\\soffice.exe"}); doesnot open my application – Harinder Jun 08 '11 at 07:09

Exit status 0 usually means no error.

Try using ProcssBuilder instead.

With ProcessBuilder you can set the working directory.

Here are some links that might help.

BTW, if you're trying to launch the app you may also try `Desktop.open()` but I'm not sure if that's what you need. – OscarRyz Jun 08 '11 at 05:28
