exit the batch file after running using java

I know how to start the batch file using java code. When i run the batch file command prompt is opened. To close the command prompt i am using the taskill /im cmd.exe. but the problem is that the command prompt that is used to start the jboss is also closed. i want to kill the cmd with a particular process id. How do i get the process id of a particular cmd promt and kill that using java

I too had the same problem. I first used as

Runtime.getRuntime().exec("cmd.exe start /c test.bat");

Then I tried as below. It works fine.

Runtime.getRuntime().exec("cmd.exe /c start test.bat");

Try this.

Here is the solution that works: to close command window after executing the commands from the batch (.bat) file you need to add "exit" (without the quotes) in a new line of your batch file. If you want to delay the execution this is the way and it works: 

public class TestSleep 
{
    public static void main ( String [ ] args ) 
    {
         System.out.println("Do this stuff");
         try 
         { 
            Thread.currentThread().sleep(3000); 
         }
         catch ( Exception e ) { }
         System.out.println("Now do everything after this");
     } 
}

Cheers

Although this seems to be an old question and probably resolved.. I struggled with the same thing for a long time.. Finally this works

String command = "cmd.exe /c build.bat";
Runtime rt = Runtime().getRuntime();
Process pr = rt.exec(command);

If you start the batch file with Runtime.exec(), it returns you a Process object. Calling the destroy() method will kill that process.

can't you add exit to your batch file to exit it's own command prompt. Uisng taskill seems overkill for just closing one command prompt, don't you think?

PS: I've never worked on batch files just the command prompt so I'm assuming it accepts the same commands.

Run the batch file with cmd.exe /c job.bat. The /c switch carries out the command and then terminates the command interpreter.
