Couldn't run bat file through Java code

Question

Problem is that the same code below is working on other machine with Windows 7. I also use Windows 7, and bat file works well. But if I try to run this bat from code written before, cmd window just blink once and disappear.

s =  path + "makeInfomap.bat";  

try {   
    p = run.exec(s); 
} catch (Exception e) {
    System.out.println(e);  
    e.printStackTrace(); 
}  

final int exitVal = p.waitFor();

Answer 1

Run don't walk to this link: When Runtime.exec() won't .

It will tell you how to gobble output and error streams and will tell you how to call the OS's command interpreter when doing similar programs (although it is a little out of date).

Answer 2

My guess is that java is calling it fine but that the batch file itself is running in to trouble.

Try adding a 'pause' as the last line of your batch file and see if the batch file's console gives you any usable information.
