How to run Perl script in Java program?

Question

Some say that the following statement can run Perl script in Java program:
Runtime.getRuntime().exec("C:\\runPerl.pl");
But when I run it, it'll throw IOException:
java.io.IOException: CreateProcess: C:\runPerl.pl error=193
at java.lang.Win32Process.create(Native Method)
at java.lang.Win32Process.<init>(Win32Process.java:63)
at java.lang.Runtime.execInternal(Native Method)
at java.lang.Runtime.exec(Runtime.java:566)
at java.lang.Runtime.exec(Runtime.java:428)
at java.lang.Runtime.exec(Runtime.java:364)
at java.lang.Runtime.exec(Runtime.java:326)
at test.runPerl.main(runPerl.java:16)
Exception in thread "main"
Where is the problem? In fact, I do have a Perl script named "runPerl.pl" in my C:/ directory. Could anybody tell me why it can't be run? Thanks in advance.

Hello sabre,
First of all thanks for your reply.
I have tried like what you mentioned.
Eventhough, i could get the exact error message.
I could get the Exception
"Exception:java.lang.IllegalThreadStateException: process hasn't exited"
<code>
import java.io.*;
public class Sample{
public static void main(String args[]) {
String s = null;
Process p;
try
     p = Runtime.getRuntime().exec("tar -vf sample.tar");
     //p.waitFor();
     if(p.exitValue() == 0)
          System.out.println("CommandSuccessful");
     else
          System.out.println("CommandFailure");
catch(Exception ex)
     System.out.println("Exception:"+ex.toString());
</code>
In this code, i tried to run the "tar command". In this command i have given -vf instead -xvf.
But it is throwing
"Error opening message catalog 'Logging.cat': No such file or directory
Exception:java.lang.IllegalThreadStateException: process hasn't exited
CommandFailure"
"Error opening message catalog 'Logging.cat'" what this line means ie,
I dont know what is Logging.cat could you explain me its urgent.
Thanks in advance.
