Executing a .bat file from my code

[Meidan]

Hi,

Is there a way to execute a .bat file from within my java code?
Something like WinExec?

Thanks.

(and overloaded variants) though it might make more sense
to 'exec' the individual commands in the .bat file of interest.

I have a sample code which shows how to run a .bat file (or any
executable file from java). :

import java.io.*;
class test{
public static void main(String arg[]){
try{
String command = "cmd /C start C:/test.bat ";
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(command);

}catch (IOException e) {
e.printStackTrace();
}
}
}

Here the .bat file is present in c:\test folder.
Hope this will b of help to u.

Something like:
Runtime.exec("command.com /c your.bat");

Something like:
Runtime.exec("command.com /c your.bat");

Or cmd.exe for win2k / xp.

More information on how to make a good use of the Runtime's exec method

HI Guys
I have tested following code this working on Win..XP, over java 1.5++.
To test this code you need to create three different files.
1. RunBatFile.java
2. RunByJava.bat
3. testFile.bat

I hope it will help us to see execution of bat file using java.
All the best.

package batfile;
import java.io.*;
class RunBatFile{

public static void main(String args[]){

try {
Runtime rt = Runtime.getRuntime();
rt.exec("RunByJava.bat");
System.out.println("Process exitValue: ");
} catch (Exception e) {
System.out.println("Unexpected exception Trying to Execute Job: " +e);
}
}
}
