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();
 }
 }

• joekarl: What sort of error are you getting? It's possible that soffice is not in you system path.
• jcomeau_ictx: please post the minimum complete code that exhibits the problem behavior, and also post the stacktrace.
• Harinder: @joekarl Exited with error code 0
• Harinder: @jcomeau-ictx na its there when i run it diretely from my comman prompt

Answer 1

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"});

• Harinder: can i first change the directory and then run "soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard"
• OscarRyz: No you can't change the directory first
• Thomas Mueller: @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.

Answer 2

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!!

Answer 3

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

1. 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.

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:\

1. 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()));

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

Answer 4

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();
 }
}

}

Answer 5

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"})

• knurdy: 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: @Harinder : I am making my last effort, I have done some edits above...try this one for me...
• Harinder: 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
• knurdy: 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
• Thomas Mueller: @knurdy you forgot the .exe after soffice in your answer (well I did as well...)

Answer 6

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.

• OscarRyz: 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.

• Harinder: na actually i am trying to run a service
