How to exec .pl files which is in a jar package?

Question

hi,
i'm new to java so hope all the experts could give me a hand on this. i've a package structure as shown below. as you can see the a.pl file is in the lib folder which will be packaged in A.jar. so how am i able to call to execute the a.pl script if the java program (A.jar) being distributed? thanks in advance for the responds.
A.jar

-src
---main.java
---utils.java
-lib
---a.pl
---b.vbs

Sorry i'm abit dump to java...Do you have a sample on
what you trying to tell me?i just not quite
understand if i getResourceAsStream is returned as
Stream then how can i pass over to a process the
arguments? thanks for the advice.Don't feel a 'dump'. This is not a trivial problem though the resultant code is quite small.
As long as you just want to supply input from the command line then this is my standard example of how you use a perl script from the jar or class path.
import java.io.*;
public class InlinePerlExecution
    public static void main(String[] args) throws Exception
        final String[] command = {
            "perl",
            "-", // '-' says take the script from stdin
            "/home/sabre/jlib", // is the command line argument for the script
        final Process process = Runtime.getRuntime().exec(command);
        new Thread(new AsyncPipe(process.getErrorStream(), System.err)).start();
        new Thread(new AsyncPipe(process.getInputStream(), System.out)).start();
        // The perl stdin to write the perl script to
        final OutputStream os = process.getOutputStream();
        // The source of the perl script - at the root of the jar or on the class path
        final InputStream is = InlinePerlExecution.class.getResourceAsStream("/wc.pl");
        // Copy the perl script to perl stdin
        new AsyncPipe(is, os).run();
        is.close();
        os.close();
        final int returnCode = process.waitFor();
        System.out.println("Return code = " + returnCode);
}You will need this utility class.
import java.io.InputStream;
import java.io.OutputStream;
public class AsyncPipe implements Runnable
    public AsyncPipe(InputStream istrm, OutputStream ostrm)
        istrm_ = istrm;
        ostrm_= ostrm;
    public void run()
        try
            final byte[] buffer = new byte[1024];
            for (int length = 0; (length = istrm_.read(buffer)) != -1; )
                ostrm_.write(buffer, 0, length);
        } catch (Exception e)
            e.printStackTrace();
    private final OutputStream ostrm_;
    private final InputStream istrm_;
}
