Call Batch file

Question

I have an JMS Subscriber that I'd like to have respond to a request by publishing to a different topic - I've setup batch files for the proof of concept - HOW DO I CALL A BATCH FILE from a java class ?

Answer 1

Like this:
import java.io.*;
public class RunProcess {
  public static void main(String[] arg) {
    try {
      Process myProcess;
      myProcess = Runtime.getRuntime().exec("cmd /c mybatch.bat");
      String s = null;
      DataInputStream in = new DataInputStream(
                           new BufferedInputStream(
                               myProcess.getInputStream()));
      while ((s = in.readLine()) != null) {
        System.out.println(s);
      System.exit(0);
    catch (IOException e) {
      System.out.println("Exception: "+ e);
      System.exit(-1);
}The InputStream/read is to display command o/p. Not absolutely necessary.
