HI- I created a batch file to do various commands. However, every time I try to run it using:
Runtime.getRuntime.exec( BAT );
BAT being the path name and batch file in a String.
I get an IOException. Is there a way to run another command prompt in the VM so I can run my batch file? Thanks

Hi,
this is the way.
try
{
Runtime r = Runtime.getRuntime();
r.exec(BAT);
}
catch(IOException e) {}
Thanks

actually, I'm having the same problem
i'm using win2k, jdk1.3
and i've tried
cmd /c blahblah.bat
command /c blahblah.bat
cmd.exe blahblah.bat
command.com blahblah.bat
start cmd blahblah.bat
and all sorts of combination...
and it still doesn't seem to work... - it just seem to "skip over" the line and didn't start a new cmd
what envir do u have?
thx

It works for me on W2K and JDK 1.4 beta.
Here is the Java code:
public class Exec {
public static void main(String[] args) throws java.io.IOException {
Runtime.getRuntime().exec("foo.bat");
}
}
Here is the batch file foo.bat:
echo bar > bar.txt
Both files are in the same directory, which is the same as the current directory. When I run "java Exec", the foo.bat batch file creates the file bar.txt.
See if you can get this example to work.
Hi Schapel,
I am encounter an exception as follows when tested with your code.I am using jdk1.3
