Problem downloading big size files

Question

Hi,
I am trying to add on my web application an hyperlink to let the user download a compressed file.
I am using the servlet to perform the transferring of the file.
Everything works perfect when the size of the file is small, otherwise I get a file smaller than the original one and the archive results to be corrupted.
Is there a limit somewhere on the hyperlink component or elsewhere?
To perform the transfer I am using the following object:
public class DownloadZip {
    /** Creates a new instance of DownloadZip */
    public DownloadZip(String fname, String mtype) {
        FacesContext faces = FacesContext.getCurrentInstance();
        HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();
        try{
        ServletOutputStream outputStream = response.getOutputStream();
        String filename = fname;
        String mimetype = mtype;
        if(mimetype == null || mimetype.length() == 0)
            mimetype = "application/octet-stream";
        response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\"");
        response.setHeader("Cache-Control", "cache");
        response.setHeader("Cache-Control", "must-revalidate");
        response.setHeader( "Pragma", "public" );
        File results=new File(path_name+filename);
        response.setContentLength((int) results.length());
        response.setContentType(mimetype);
        FileInputStream in = new FileInputStream(results);
        BufferedInputStream fis = new BufferedInputStream(in);
         int i = fis.read();
        while (i !=-1)
     try
             outputStream.write(i);
          i = fis.read();
     catch(IOException e)
          e.printStackTrace();
          break;
    outputStream.flush();
    fis.close();
    outputStream.close();
    catch(IOException e)
          e.printStackTrace();
}Please tell me what I am doing wrong.
Eva.

Yes. This is an issue. JavaFX team is working on enhacing HttpRequest API so as to allow huge data transfer. There are couple of new attributes added which will allow to do data transfer without buffering. Also Integer (used in may APIs) will be changed to use Long (new supported data type) to handle larger data. These changes will be available in next release - 1.2
