Question

I am trying to fire the following command on a windows(that came as part of a product we have bought):

start /wait setup /z"/sfC:\temp\input_file.txt" /s /f2"C:\temp\newlogfile.log"

Now the sad part is that I am failing to run the command using a java program that I wrote. (I have to run it as a part of something else, hence the need of running it through java)

Here is my code:

String[] cmd = new String [6];

cmd[0] = "start";
cmd[1] = "/wait";
cmd[2] = "setup";
cmd[3] = "/z\"/sfC:\\temp\\input_file.txt\"";
cmd[4] = "/s";
cmd[5] = "/f2\"C:\\temp\\newlogfile.log\"";


try
{
    Runtime.getRuntime().exec(cmd);
}                               
catch(IOException e)    
{   
    e.printStackTrace();
}

Please tell me what I am doing wrong here.
This is the output I am getting:

java.io.IOException: CreateProcess: start /wait setup /z"/sfC:\temp\input_file.txt" /s /f2"C:\temp\newlogfile.log" error=2

Try with this:

String[] cmd = { 
    "cmd.exe", 
    "/c", 
    "start", 
    "/wait", 
    "setup",
    "/z\"/sfC:\\temp\\input_file.txt\"", 
    "/s",
    "/f2\"C:\\temp\\newlogfile.log\"" 
};

Runtime.getRuntime().exec(cmd);

Reason: start is an internal command available only from inside a cmd shell.
