问题描述

错误是:

java.io.IOException: Resource could not be found 
http://www.abc.com/ABC.cod:411 - Length Required.

当我按下下载按钮时，代码将执行&我在blackbarry中收到此错误.在Windows&诺基亚手机正在下载Jad文件&然后抛出错误的贾德不支持，这是可以的.

Blackbarry是RIM os mobile，为什么会引发错误，请帮助我.

我的开发代码是这样的:
此代码位于按钮单击事件中

Blackbarry is RIM os mobile tht why this throws error plz help me for tht.

my develop code is like this:
this code is in button click event

mFileName = "ABC.jad";
mContentType = "text/vnd.sun.j2me.app-descriptor";

bool succ = ResponseFile(Page.Request, Page.Response, mContentType,
        mFileName, Server.MapPath("~/" + mFileName), 1024000);
if (!succ)
{
   Response.Write("Download Error");
}
Response.End();

此功能用于下载文件:

this function is used to download file:

public static bool ResponseFile(HttpRequest _Request, HttpResponse _Response,string _ContentType, string _fileName, string _fullPath, long _speed)
    {
        try
        {
            FileStream myFile = new FileStream(_fullPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
            BinaryReader br = new BinaryReader(myFile);
            try
            {
                _Response.AddHeader("Accept-Ranges", "bytes");
                _Response.Buffer = false;
                long fileLength = myFile.Length;
                long startBytes = 0;
                int pack = 10240; //10K bytes
                int sleep = (int)Math.Floor((double)(1000 * pack / _speed)) + 1;
                if (_Request.Headers["Range"] != null)
                {
                    _Response.StatusCode = 206;
                    string[] range = _Request.Headers["Range"].Split(new char[] { '=', '-' });
                    startBytes = Convert.ToInt64(range[1]);
                }
                _Response.AddHeader("Content-Length", (fileLength - startBytes).ToString());
                if (startBytes != 0)
                {
                    _Response.AddHeader("Content-Range", string.Format(" bytes {0}-{1}/{2}", startBytes, fileLength - 1, fileLength));
                }
                _Response.AddHeader("Connection", "Keep-Alive");
                _Response.ContentType = _ContentType;
                _Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(_fileName, System.Text.Encoding.UTF8));
                br.BaseStream.Seek(startBytes, SeekOrigin.Begin);
                int maxCount = (int)Math.Floor((double)((fileLength - startBytes) / pack)) + 1;
                for (int i = 0; i < maxCount; i++)
                {
                    if (_Response.IsClientConnected)
                    {
                        _Response.BinaryWrite(br.ReadBytes(pack));
                        Thread.Sleep(sleep);
                    }
                    else
                    {
                        i = maxCount;
                    }
                }
            }
            catch
            {
                return false;
            }
            finally
            {
                br.Close();
                myFile.Close();
            }
        }
        catch
        {
            return false;
        }
        return true;
    }
