run bat file from java program

[AdverseDeviant]

i have a bat file that i want to run from a java program that creates that bat file. Ive looked around but i dont see anything straight forward. something about a runtime class? Can anyone help me out? Thanks.

Ok, here's a quick example that runs an external command and outputs the exit code.

One thing to bear in mind here is that the 'waitFor' method means the parent app will halt until the child app has completed (useful if you need the output to make decisions from prior to resuming).

This was just a quick google, more detail can be found here (including a non-halting example): http://www.rgagnon.com/javadetails/java-0014.html

import java.io.*;
public class CmdExec {
  public static void main(String argv[]) {
    try {
	  String line;
	  Process p = Runtime.getRuntime().exec("test.cmd");
	  p.waitFor();
	  System.out.println(p.exitValue());
    }
    catch (Exception err) {
	  err.printStackTrace();
    }
  }
}
[/CODE]
