java ftp删除文件的问题

[a252353632]

我没有积分，没办法给分了
代码如下，执行fc.sendServer(del) 的时候只能每次删除2、3个文件？问题何在？我执行的是删除7个文件的啊

public class ftpDown{
	FtpClient fc;
	boolean loginOK;  //用来判断是否正常连接服务器
	
	public static void main(String[] args){
		Object[] fileList;
		String[][] address = {
				{"83.16.16.72", "oracle", "fxpg7065"},
				{"83.16.21.121", "admin", "a123456"}
		};
		String[] dir = {"oracle\\iostat_log", "oracle\\vmstat_log"};
		ftpDown fDown = new ftpDown();
		//测试，所以暂且一次循环
		for(int a = 1; a < 2; a++){
			fDown.connect(address[a][0], address[a][1], address[a][2]);
			
			if(fDown.loginOK){
				System.out.println("***************************************");
			
				for(int d = 1; d < 2; d++){
					fileList = fDown.getFileList(dir[d]).toArray();
					Arrays.sort(fileList); //文件排序，保证取得的文件是最老的那些
					int dirLen = dir[d].length();
					int count = 0;
					
					//一周生成7个文件，用8来保证第七个文件已经写入完毕
					if(fileList.length < 8){
						System.out.println("  还没有生够一周的文件(7个)");
					}
					else if(fileList.length > 7){
						for(int i = 0; i < 7; i++){
							boolean isOK = fDown.downLoadFile(dirLen, (String)fileList[i]);
							if(isOK){ //如果成功下载
								count++;
							}
						}
					}
					
					//如果7个文件成功下载本地，则删除服务器上的该文件
					if(count == 7){
						for(int i = 0; i < 7; i++){
							fDown.deleteLoadFile((String)fileList[i]);
						}
					}
				}
				System.out.println("***************************************");	
			}
			fDown.stop();
		}
	}
	
	//获得fileDir目录下的所有文件列表
	public ArrayList getFileList(String fileDir){
		ArrayList aList = null;
		try {
			BufferedReader br = new BufferedReader(new InputStreamReader(fc.nameList(fileDir)));
			aList = new ArrayList();
			String s = "";
			while((s = br.readLine()) != null){
				aList.add(s);
			}
		}catch (IOException e) {
			System.out.println("获取文件列表出错");
		}
		
		return aList;
	}
	
	//下载文件
	public boolean downLoadFile(int dirLen, String fullFileName){
		boolean result = false;
		if(fc != null){
			try{
				int ch;
				String savePath = System.getProperty("user.dir");
				String shotName = fullFileName.substring(dirLen + 1, fullFileName.length());
				File fl = new File(savePath + "\\" + shotName);
				RandomAccessFile getFile = new RandomAccessFile(fl, "rw");
				getFile.seek(0);
				TelnetInputStream fget = fc.get(fullFileName);
				DataInputStream puts = new DataInputStream(fget);
				System.out.print("正在下载 " + shotName + "，请等待...");
				while((ch = puts.read()) >= 0){
					getFile.write(ch);
				}
				
				fget.close();
				getFile.close();
				System.out.println("	下载成功");
				result = true;
			}catch(IOException e){
				result = false;
				System.out.println("	下载失败" + e);
			}
		}
		else
			result = false;
		
		return result;
	}
	
	public void deleteLoadFile(String fileName){
		if(fc != null){
			String del = "DELE " + fileName + " \r\n";
			System.out.print(del); //输出执行的命令
			fc.sendServer(del);
		}
	}
	
	public FtpClient connect(String hostName, String uid, String pwd){
		System.out.println("正在连接 " + hostName + "，请等待...");
		try {
			fc =new FtpClient(hostName);
			fc.login(uid, pwd);
			fc.binary();
			System.out.println("连接主机 " + hostName + " 成功");
			loginOK = true;
		}catch (FtpLoginException ef) {
			System.out.println("请检查用户或密码是否正确！");
			loginOK = false;
		}catch (Exception en) {
			System.out.println("无法与主机连接！");
			loginOK = false;
		}
		return fc;
	}
	
	public void stop(){
		try {
			if(fc != null){
				fc.closeServer();
				System.out.println("与主机连接已断开");
			}
		} catch (IOException e) {
			System.out.println("与主机断开失败" + e);
		}
	}	
}

fc.sendServer(del);后少加了一句
fc.readServerResponse();
