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.getRuntime();
            r.exec("perl mydir/rename.pl");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

"doesn't work" is too vague. If it has <STDIN> is the perl programming waiting for some user input?

[bdan44]

yes. the perl script needs some user input. however, the java program doesn't provide an oppurtunity for the user to provide said input, or at least it doesn't in its present state.

Seems like a JAVA question. There is a perl module called Expect but I don't know if it will work in this situation.

Moving thread to the Java Forum.
