在FtpClient中用ftp FTP命令建自己要用的东东。。

由于sun没有公开FtpClient的API所以我们將就使用Sun的未公开类别暫時應急一下，方法命名大多與Common net ftpClient 雷同，不足的只好用issueCommand自己丟FTP命令：
 
import java.io.FileNotFoundException;import java.io.IOException;import java.net.Proxy;import sun.net.TelnetInputStream;import sun.net.TelnetOutputStream;import sun.net.ftp.FtpClient;public class SundFtpClient extends FtpClient {  public static final int   ASCII_FILE_TYPE =0;  public static final int   BINARY_FILE_TYPE=2;  public SundFtpClient(String host) throws IOException {    super(host);  }  public SundFtpClient(String host, int port) throws IOException {    super(host, port);  }  public int issueCommand(java.lang.String cmd) throws IOException{    return super.issueCommand(cmd);  }  public void issueCommandCheck(java.lang.String cmd) throws IOException{    super.issueCommandCheck(cmd);  }  public boolean setFileType(int fileType)throws IOException{    if(fileType==ASCII_FILE_TYPE){      return issueCommand("TYPE A")==1;    }else{      return issueCommand("TYPE B")==1;    }  }  public void enterLocalPassiveMode(){    try{      issueCommand("PASV");    }catch(IOException e){}  }  public boolean isConnected(){    return this.serverIsOpen();  }  public void connect(java.lang.String hostname)throws java.io.IOException{    this.disconnect();    this.openServer(hostname);  }  public void connect(java.lang.String hostname,int port)throws java.io.IOException{    this.disconnect();    this.openServer(hostname,port);  }  public void disconnect()throws java.io.IOException{    if(this.serverIsOpen())      this.closeServer();  }  public boolean deleteFile(String pathname)throws java.io.IOException{    try{      return issueCommand("DELE "+pathname)==1;    }catch(FileNotFoundException e){      return false;    }  }  public boolean makeDirectory(String pathname)throws java.io.IOException{    try{      return issueCommand("MKD "+pathname)==1;    }catch(FileNotFoundException e){      return false;    }  }  public boolean removeDirectory(String pathname)throws java.io.IOException{    try{      return issueCommand("RMD "+pathname)==1;    }catch(FileNotFoundException e){      return false;    }  }  public boolean sendNoOp()throws java.io.IOException{    return issueCommand("NOOP")==1;  }  public String printWorkingDirectory()throws java.io.IOException{    return super.pwd();  }  public boolean changeToParentDirectory()throws java.io.IOException{    return issueCommand("CDUP")==1;  }  public boolean changeWorkingDirectory(String pathname)throws java.io.IOException{    try{      return issueCommand("CWD "+pathname)==1;    }catch(FileNotFoundException e){      return false;    }  }  public void storeFile(String remote,java.io.InputStream local)throws java.io.IOException{    byte[] buf = new byte[1024];    int readed=0;    TelnetOutputStream outs = this.put(remote);    synchronized (local) {     while((readed=local.read(buf,0,1024))>0)        outs.write(buf,0,readed);      outs.flush();      outs.close();      local.close();    }  }  public void retrieveFile(String remote,java.io.OutputStream local)throws java.io.IOException{    byte[] buf = new byte[1024];    int readed=0;    TelnetInputStream ins = this.get(remote);    synchronized (local) {      while((readed=ins.read(buf,0,1024))>0)        local.write(buf,0,readed);      local.flush();      local.close();      ins.close();    }  }}测试代码：import java.io.IOException;import sun.net.ftp.FtpLoginException;/*
