Perl in Java

[bdan44]

HI,
I have a perl script that I want to call in java. I can call it, the only problem is that the perl script has <STDIN> and the perl sciprt doesn't work. Other perl scripts(without <STDIN>) do work however. here is my code:
import java.util.*;
import java.io.*;
class Rename {
public static void main(String args[]) {
try {
Runtime r = Runtime.getRunt ime();
r.exec("perl mydir/rename.pl");
} catch (Exception e) {
e.printStackTra ce();
}
}
