Servlet Program doesnt work in Client Side.

[Chella]

Hi,
In my web application,I have to download a zip file from ftp server and unzip that file to local system.I have written a servlet code and got the output successfully in server system(my system).The problem is when i run this servlet from client (another system),the zip file get unzips in server system only.not in client. I dont know where is the problem and what is the problem.. I could not able to find any solution. Please provide me some solutions or suggestions.Any body have got these kind of errors? I have used Streams to download and unzip a zip file and an input dialog box in swing to get destination folder path from client (to store the unzipped files). Below the complete code.

public class Unzip extends HttpServlet
{
public void doGet(HttpServletRequest req,HttpServletResponse res) throws IOException,ServletException
 
{
 
PrintWriter pw=res.getWriter();
RequestDispatcher rd=null;
byte[] buffer = new byte[16384];
File f2 = new File("some.zip");
OutputStream one = new FileOutputStream(f2);
 

try
{
URL url = new URL("ftp://ipaddress/folder/somefile.zip");
URLConnection con = url.openConnection();
BufferedInputStream fis=new BufferedInputStream(con.getInputStream());
fis= new BufferedInputStream(con.getInputStream());
byte[] buf = new byte[4 * 1024]; // 4K buffer
int bytesRead;
while ((bytesRead = fis.read(buf)) != -1)
one.write(buf, 0, bytesRead);
}
catch(Exception e)
{}
 

// Input Dialog Box to get destination path
String str = JOptionPane.showInputDialog("Enter the destination folder path.e.g:\" C:\\new\"");
 
ZipFile zip=new ZipFile(f2);
Component parentComponent=null;
File outputDir=new File(str);
 
if (zip == null)
{
throw new NullPointerException("outputDir is null");
}
int size = zip.size();
if (size > 0) {
if (outputDir == null)
{
throw new NullPointerException("outputDir is null");
}
if (!outputDir.exists())
{
outputDir.mkdirs();
}
 
Enumeration entries = zip.entries();
for ( int i = 0; entries.hasMoreElements(); ) {
ZipEntry entry = (ZipEntry) entries.nextElement();
File File = new File(outputDir, entry.getName());
File.getParentFile().mkdirs();
if (!entry.isDirectory()) {
InputStream in = null;
OutputStream out = null;
try
{
in = zip.getInputStream(entry);
out = new FileOutputStream(File);
for (int n = 0; (n = in.read(buffer)) > -1; )
out.write(buffer, 0, n);
}
finally {
if (out != null)
{
try
{
out.close();
}
catch (IOException e)
{
pw.println(e);
}
}
}
}
}
}
}
}
