public static void main(String[] args) {
     Runtime runtime = Runtime.getRuntime();

     }
     catch(IOException ioException)

Answer 1

My first try will be to create a shared folder in windows, so you can access to remote file in the same way you do now:

 Process p1 = runtime.exec("cmd /c \\alias_of_folder\\sample.bat");

If create shared folder is not an option, what you need is to open an connection to the other computer from with your Java application.

• OpenSSH site has information that will give ou ssh support in Java .
• Also check JSch and it's examples .

UPDATE from this answer :

You can also combine Jsch with Expect4j and this way have a better control on the commands you want to execute ( nice example here ).
