How can I execute a Windows batch file as a separate process from Java?

Question

I'm writing a class in Java which will be calling a Windows batch file. When I run this class, the batch file is getting opened and getting closed. How can I make the batch file continue to run after the Java program terminates?

Answer 1

You are probably calling the batch with cmd /c batch.cmd. If you use /k instead of /c the window will stay open after the batch ran.

Answer 2

See this article for how to use Runtime.exec properly.

You probably need to start a new command line window:

Runtime rt = Runtime.getRuntime();
String[] commandArgs = new String[]{"cmd", "/C", "start", "c:\\test.bat" };
Process proc = rt.exec(commandArgs);
