Open a Local file from JSP

Question

Hi All,
I want to access a local file from a JSP. On click of the link the local file should open. The location of the local file is
O:/VWS00000000000000000001/REPORT_FRAGMENTS/Title1.doc
and the hyper link on the JSP shows
file:///O:/VWS00000000000000000001/REPORT_FRAGMENTS/Title1.doc
somehow the file does not open from the JSP page but it opens from the browser if I type
'file:///O:/VWS00000000000000000001/REPORT_FRAGMENTS/Title1.doc' in the address bar.
Can anybody please help.
regards,
Shardul.

if you'd like to show the real path to the user, use simply an ftp server !
however, if you prefer a secure solution, so use a servlet:
example:
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class SendWord extends HttpServlet {
  public void doGet(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
    //get the 'file' parameter
    String fileName = (String) request.getParameter("file");
    if (fileName == null || fileName.equals(""))
      throw new ServletException(
          "Invalid or non-existent file parameter in SendWord servlet.");
    // add the .doc suffix if it doesn't already exist
    if (fileName.indexOf(".doc") == -1)
      fileName = fileName + ".doc";
    String wordDir = getServletContext().getInitParameter("word-dir");
    if (wordDir == null || wordDir.equals(""))
      throw new ServletException(
          "Invalid or non-existent wordDir context-param.");
    ServletOutputStream stream = null;
    BufferedInputStream buf = null;
    try {
      stream = response.getOutputStream();
      File doc = new File(wordDir + "/" + fileName);
      response.setContentType("application/msword");
      response.addHeader("Content-Disposition", "attachment; filename="
          + fileName);
      response.setContentLength((int) doc.length());
      FileInputStream input = new FileInputStream(doc);
      buf = new BufferedInputStream(input);
      int readBytes = 0;
      while ((readBytes = buf.read()) != -1)
        stream.write(readBytes);
    } catch (IOException ioe) {
      throw new ServletException(ioe.getMessage());
    } finally {
      if (stream != null)
        stream.close();
      if (buf != null)
        buf.close();
  public void doPost(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
    doGet(request, response);
}hope that helps
