Hi,

I want to start the command prompt window from my java program.
Tried using Runtime but its not working.These are my codes :


String command = "cmd.exe";
try {
child = Runtime.getRuntime().exec(command);
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Actually, its working when i change the value of command, like ita working when i put "notepad.exe". May be i m using a wrong command for cmd prompt. If anyone can figure it out, then i will be really thankful.

When you say it's not working, do you get an error message?

no i am not getting any error message. All other parts of the program are working well.Just at the end the command prompt is supposed to open.but it isnt doing so (

Not sure if this will work, but the command for opening the cmd shell in a batch file is simply cmd. Maybe try changing the line
to simply
and see what happens?

EDIT: Actually, if that doesn't work, try "start" instead of "cmd" as that is the command to open a new CMD shell from a running CMD shell.

It might also be worthwhile pointing out that this code will only work on windows operating systems. Really you should probably have this in an if-statement to ensure running this code only in a windows environment. An else statement might allow you to open a different shell in Linux, Mac, other environments?

Thanks,
Actually i did try "cmd" , and it was all the same. But i m trying again , will tell u the result.

hey dear, its not working.
i tried using "start" but its showing error

I am using Windows. But i am doing everything in Eclipse.Hope that doesnt make any difference.

Sorry manisha but I am out of ideas. Maybe someone else can help you?

its ok, thanx a lot for making an effort
