错误的文件数插座异常而从上载到服务器文件 [英] Bad File Number Socket Exception While Uploading file from server

问题描述

我想从Android的SD卡到FTP Web服务器上传文件。对于这个我使用Apache FTPClient库。
这里是我的code上传文件...

I am trying to upload file from android sdcard to FTP Web server. For this i am using Apache FTPClient library. Here is my code to upload file ...

FTPClient con = new FTPClient();
                try
                {                       
                    con.connect("host ip",21);

                    int reply = con.getReplyCode();

                    if (!FTPReply.isPositiveCompletion(reply))
                    {
                        con.disconnect();
                        System.err.println("FTP server refused connection.");
                        System.exit(1);
                    }else{
                        System.err.println("FTP server connected");                         
                    }

                    if (con.login("username", "password"))
                    {
                        con.enterLocalPassiveMode(); // important!

                        FileInputStream in = new FileInputStream("/mnt/sdcard/xmls/" + fileName);


                        boolean result = con.storeFile("/"+filename, in);

                        if (result){
                            Toast.makeText(DisplaySDCardContent.this, "File Uploaded Successfully.", Toast.LENGTH_LONG).show();
                            Log.v("upload result", "succeeded");
                        }

                        in.close();
                    }
                }

在尝试上传文件...我得到的例外，说坏的文件号..插座例外...

While try to upload file ... i am getting exception that says bad file number .. socket exception...

推荐答案

尝试获得了Apache FTPClient 3.0.1。这似乎是在3.0出现了错误。

Try getting the Apache FTPClient 3.0.1. It seems like there was bug in the 3.0.
