jsp：怎么实现点击下载按钮直接下载文件而不是在浏览器中直接打开

点击按钮下载的时候会有一个弹出框，可以选择是打开还是下载，请大神们给出一个代码实例

//强制要求为下载，防止有些浏览器调用默认打开程序打开而不下载
response.setContentType("application/force-download");

    //获取文件
    File fileLoad = new File(path);
    //下载时文件显示的名字
    String fileDisplayName = null;

    try {
        if(displayFileName != null && (!"".equals(displayFileName))){
            fileDisplayName = URLEncoder.encode(displayFileName, "UTF-8");
        }else{
            fileDisplayName = fileLoad.getName();
        }
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

    //设置下载时的文件名
    response.setHeader("Content-disposition", "attachment;filename="+fileDisplayName);
    //当下载文件名为中文等Unicode字符时，可能导致乱码，此时需要将文件名重新编码为UTF-8
    //采用ISO8859-1编码 
    //response.setHeader("Content-disposition","attachment; filename="+new String(fileLoad.getName().getBytes("iso-8859-1"),"UTF-8"));
    //采用UTF-8编码 
    //response.setHeader("Content-disposition","attachment; filename="+URLEncoder.encode(fileLoad.getName(), "UTF-8"));

    try {
        OutputStream ops = null;
        FileInputStream fis = null;

        long fileLength = fileLoad.length();
        String length = String.valueOf(fileLength);
        response.setHeader("Content_Length", length);

        ops = response.getOutputStream();
        fis = new FileInputStream(fileLoad);
        byte b[] = new byte[2048];
        int i = 0;
        while((i = fis.read(b))!= -1){
        ops.write(b, 0, i);
        }
        ops.flush();
        if(fis != null){
        fis.close();
        fis = null;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

想问一下，download.jsp应该放在什么路径下

下载文件
