Save As feature in JSP

Question

Hi there,
I have a JSP where the user needs to be shown a dialog box onclicking the "Browse" button (like the "Save As" feature on browser right click).
Currently the way I have it is that I have used Input type="file" in my form in the JSP.
But the problem is that this will not allow non-existing new filenames to be entered.
But the good thing was that I didnt have to program anything for the MS window to browse the filesystem.
Is there something like this for "Save as" or do I have to explicitly program for this.
I'd really appreciate your help.
Thanks in advance!

And here is the code scriptlet.....
<%@ taglib uri="/coreTaglib" prefix="core" %>
<%@ taglib uri="/dspTaglib" prefix="dsp" %>
<%     try {
               String fileName = "C:\\Temp\\Baseline_Export.xls"; //request.getParameter("fileName");
               File f = new File(fileName);
               if(!f.exists() || f.isDirectory()) { throw new Exception("The requested file does not exist.");     }               
               String ctype = "application/vnd.ms-excel";
               response.setContentType(ctype);               
               response.setContentLength((int)f.length());               
               byte[] buffer = new byte[1024];               
               int r = 0;               
               FileInputStream fin = new FileInputStream(f);               
               OutputStream out1 = response.getOutputStream();               
               while((r = fin.read(buffer, 0, buffer.length)) != -1) {                    
                    out1.write(buffer, 0, r);               
               try {                    
                    fin.close();                    
                    out1.flush();                    
                    out1.close();               
               } catch(Exception e) {}               
               out1 = null;               
               fin = null;               
               buffer = null;
          catch (Exception ex){
               String msg = ex.getMessage();     
               System.out.println("Exptn in ExcelRenderer...."+ex);          
               response.setContentType("text/html");               
               response.setContentLength(msg.length());               
               PrintWriter out2 = response.getWriter();               
               out2.println(msg);               
               out2.flush();               
               out2.close();
