using Runtime class on Windows platform

Posted: Mar 14, 2003 1:59 PM

Hi,

I have a JRE in Windows and am trying to do the following:

Runtime run = Runtime.getRuntime();
String[] cmd = {"ping", "10.10.10.1"};
run.exec(cmd);

I am able to do the ping from the cmd window. When I run this Java program, the DOS window opens and just hangs. It seems like it invoked the ping.exe and just hangs. I also tried setting the environment by including the Path etc..but still doesnt work.

Any help is greatly appreciated..

Thanks

Works4me on 1.4 ,Win XP.

From java.lang.Process javadoc
<pre>
The Runtime.exec methods may not work well for special processes on certain native platforms, such as native windowing processes, daemon processes, Win16/DOS processes on Win32, or shell scripts. The created subprocess does not have its own terminal or console.
</pre>

Try to invoke Process.getInputStream() on created process to get more info.

Process proc = run.exec(cmd);
proc.getInputStream();
