CreateProcess error=2, The system cannot find the file specified

Question

I am writing a program in java which would execute winrar and unzip a jar file for me placed in h:\\myjar.jar into the folder h:\\new. My java code

Answer 1

I used ProcessBuilder but had the same issue. The issue was with using command as one String line (like I would type it in cmd) instead of String array. In example from above. If I ran

ProcessBuilder pb = new ProcessBuilder("C:/Program Files/WinRAR/winrar x myjar.jar *.* new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

I got an error. But if I ran

ProcessBuilder pb = new ProcessBuilder("C:/Program Files/WinRAR/winrar", "x", "myjar.jar", "*.*", "new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

everything was OK.
