如何用JAVA编写FTP客户端的STOR命令，也就是上传一个文件到FTP服务器。

代码如下； (不知哪里出错）

else if(clavier.startsWith("STOR"))
            {
                BufferedReader fichier=new BufferedReader(new FileReader(new           File("c:\\email.txt")));
                writeCommand("PASV");  //INPUT KEYBOARD
                getPortNumber(br);    //GET NUMBER OF PORT 
                
                
                writeCommand("STOR c:\\2007\\email.txt");
                reponseServer();   
                sockData=new Socket(ip,portdata);
                BufferedWriter brdataout=new BufferedWriter(new OutputStreamWriter(sockData.getOutputStream()));
                reponseServer();
                String bytesRead;
                while((bytesRead=fichier.readLine())!=null){
                brdataout.write(bytesRead);
                }
                   reponseServer();
                   System.out.println("abc");
                reponseServerdata(brdata);
                reponseServer();
                
                
                
            }

非常感谢，
