Package required to execute perl script

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, I've serious doubt in executing perl scripts in java. I got to know, that using scalar refernce in Java, the array can be passed to perl. After this, i want to execute the perl in java using Getruntime.exec() command

My question is using JDK, i'm not able to execute this java code. What package i need to import in java, to run scalar refernce & running the perl after that

I'm pasting a sample code, of what i need to do. Please help me out in this

 To pass the array to perl using scalar referencing

  public class arrayforPerl {
  perl void max( int[] data ) {{
        # Get the array elements
        #
        my @arrPerl = GetIntArrayElements( $data );        
          }} ## double braces are for the perl code

    void maxProg() {
        int[] data = {101, 99, 42, 666, 23};
        max( data );
    }

    public static void main(String[] argv) {
        arrayforPerl javaPerl = new arrayforPerl();
        javaPerl.maxProg();
    }
}

This is a Java question, not a Perl question. I would ask whoever gave you the code about what packages you need. In Java, you usually have import statements that import packages from `com.wherever.something`.	[reply] [d/l]

Hi! I've used the Sample class on http://vishnuagrawal.blogspot.com/2008/08/execute-perl-script-from-java-program.html and replaced the command string in `process = Runtime.getRuntime().exec("perl test.perl");` [download] by an array of strings: `String [] perlCommand = {"perl","test.perl","1","2","3"}; process = Runtime.getRuntime().exec(perlCommand);` [download] My perl test script looks like this: `#!/usr/local/bin/perl use strict; use warnings; use Data::Dumper; print Dumper @ARGV;` [download] Best wishes.

It's not at all clear to me what this you expected to happen and what didn't happen. This also seems more of a question for the programmers who imported Perl into Java to me. That is, unless you're seeing some Perl error you forgot to mention.programmers	[reply]
