Hi,
What type of output you expected. If you want to cmd output from process then use following code
String[] cmd = new String[4];
cmd[0] = "cmd.exe";
cmd[1] = "/C";
cmd[2] = "start";
cmd[3] = "run.bat";
Process p=Runtime.getRuntime().exec(cmd);
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
     pingResult += inputLine;
in.close();
p.waitFor();Edited by: sagar_birari on Mar 26, 2008 4:47 AM
