手机 从 Servlet 下载文件 问题!!急
IE从该servlet就能下载,但是手机WIFI从这里下载就不行,下载文件是.apk文件(安卓的应用),如何解决呢?谢谢

具体代码如下:

Java code
@Override    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException    {        try        {            // path是指欲下载的文件的路径。            String path = "D:\\apps\\Resource\\bin\\android\\android.apk";            File file = new File(path);            // 取得文件名。            String filename = file.getName();            // 取得文件的后缀名。            // String ext = filename.substring(filename.lastIndexOf(".") +            // 1).toUpperCase();            // 以流的形式下载文件。            InputStream fis = new BufferedInputStream(new FileInputStream(file));            byte[] buffer = new byte[fis.available()];            fis.read(buffer);            fis.close();            // 清空response//            response.reset();            // 设置response的Header            response.addHeader("Content-Disposition", "attachment;filename="                    + new String(filename.getBytes("utf-8"), "utf-8"));            response.addHeader("Content-Length", "" + file.length());            OutputStream toClient = new BufferedOutputStream(response.getOutputStream());            response.setContentType("application/octet-stream");            toClient.write(buffer);  //这句手机访问的话就报错,错误在下面            toClient.flush();            toClient.close();        }        catch(IOException ex)        {            ex.printStackTrace();        }    }
