runtime.exec

I'd like to call the java keytool during runtime execution providing dynamic arguments. Here's what is working under Windows, but not under Linux (Ubuntu) same Java 1.6.0: File f = new File("mykey.jks"); StringBuilder command = new StringBuilder(); command.append(System.getProperty("java.home") + System.getProperty("file.separator") + "bin" + System.getProperty("file.separator") + "keytool"); command.append(" -genkey"); command.append(" -dname \"cn=foo,ou=bar,o=company,c=CH\""); command.append(" -alias myProduct"); command.append(" -keypass " + "testtest"); command.append(" -keystore " + f

I'm using Runtime.getRuntime().exec in eclipse to run another java program from the current program. I've used the following code. InputStreamReader isr=new InputStreamReader(System.in); BufferedReader br=new BufferedReader(isr); System.out.println("Enter the class name"); String s=br.readLine(); String str="XYZ"; String[] cmd = {"java","-cp", "C:/Users/..../workspace/Testing/bin",s,str}; Process pro=Runtime.getRuntime().exec(cmd); I'm also passing a string "XYZ" to that program. That program just accepts the string and displays Your string is XYZ But by using the line String[] cmd = {"java","

I want to exceute a simple command which works from the shell but doesn't work from Java. This is the command I want to execute, which works fine: soffice -headless "-accept=socket,host=localhost,port=8100;urp;" This is the code I am excecuting from Java trying to run this command: String[] commands = new String[] {"soffice","-headless","\"-accept=socket,host=localhost,port=8100;urp;\""}; Process process = Runtime.getRuntime().exec(commands) int code = process.waitFor(); if(code == 0) System.out.println("Commands executed successfully"); When I run this program I get "Commands executed

I'm writing a java application where I require to run a process in background throughout the lifetime of the running application. Here's what I have: Runtime.getRuntime().exec("..(this works ok).."); Process p = Runtime.getRuntime().exec("..(this works ok).."); InputStream is = p.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); So, basically I print out every br.readLine() . The thing that I'm not sure about is how to implement this code in my application because wherever I put it (with Runnable), it blocks other code from

I have compiled ffmpeg library on ubuntu 11.10 and ported compiled files on android. After compiling i got libffmpeg.so successfully. It gets loaded on android successfully. I am doing it on ubuntu 11.10 eclipse android emulator. I have created a small test application which act as command prompt which accepts command from user and displays result. (testing ffmpeg commands) When i run simple commands like "ls", "ls -l" it works perfectly. but when i simply type " cd mnt " or " ffmpeg " as command and try to run it. I got Warnings in Logcat saying that 08-26 16:44:52.553: W/System.err(5961):

try { Runtime.getRuntime().exec("excel C:\\file.xls"); } catch (IOException ex) { System.out.println(ex); } Doesn't work. I have to put the full path of excel.exe in order to work. How can I make it generic (For any Excel Folders/Versions)? When I run the same line from OS with Windows Run (Start --> Run) it works. Is there a code in Java to simulate Windows' Run command? Why don't you try with the Desktop class (api doc here ) introduced in JDK6 that has the method public void open(File file) throws IOException which is documented as what you want to do: Launches the associated application to
