NEED PARAMETER PASSING SAMPLE INSTALLATION ZIP FILE...

Question

Hello All,
I was viewing the following page:
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/
articles/guidelines.parameter.passing.html
Near the end of the page it reads, "For a detailed PL/SQL portlet
sample, see the Parameter Passing sample included in the PL/SQL
section including the Parameter Passing Sample Installation
article and check out the source code in the downloadable zip
file."
The phrase "downloadable zip" near the end of this line is a link
that is supposed to provide you with the zip file. When I click
on this link I get the file to save as sample.zip. Files get
downloaded but when I try to unzip it,
I encounter error messages :
Missing 1 bytes in Zip file (attempting to process anyway).
Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again.

let say i have a code as below:
public void init()
      String rootDirectory = JOptionPane.showInputDialog( this,
         "Please enter a directory name:" );
      FileTreePanel panel = new FileTreePanel( rootDirectory );
      getContentPane().add( panel );
   }and i use this code to call the batch file:
import java.io.IOException;
public class callbatch{
     public static void main(String args[]) {
          try {
               Runtime runtime=Runtime.getRuntime();
               Process process=runtime.exec("cmd /c start callnvcc.bat");
               catch(IOException ioe) {
                    System.out.println(ioe);
     }how can i pass the rootDirectory into my callnvcc.bat?
