我用jsp实现ftp上传功能，但是客户端不能往服务器端传上传文件，服务器端自己可以上传文件，代码如下：
private String ftpServer;
private String ftpPort;
private String ftpUserName;
private String ftpPassword;
private FTPClient ftpClient;
private boolean isLogin = false;

public void connServer(String pFtpServer, String pFtpPort,
String pFtpUserName, String pFtpPassword) throws
Exception {
this.ftpServer = pFtpServer;
if (pFtpPort.trim().equals("")) {
this.ftpPort = "21";
} else {
this.ftpPort = pFtpPort;
}
if (pFtpUserName.trim().equals("")) {
this.ftpUserName = "Anonymous";
} else {
this.ftpUserName = pFtpUserName;
}
this.ftpPassword = pFtpPassword;
try {
ftpClient = new FTPClient(); //ftpServer, Integer.parseInt(ftpPort)
ftpClient.setRemoteHost(ftpServer);
ftpClient.setRemotePort(Integer.parseInt(ftpPort));
ftpClient.setControlEncoding("gb2312"); //加上这一句后在 edtftpj 2.0.1 下就要可以传中文文件名了
System.out.println("开始登录");
ftpClient.connect();
ftpClient.login(ftpUserName, ftpPassword);
System.out.println("登录成功");
ftpClient.chdir("\\"); //在有的ftp服务器运行会出错，用ftpClient.chdir("/")又可以了
System.out.println("已转入根目录");
isLogin = true;
} catch (Exception e) {
throw new Exception(e.getMessage());
}
}

//上传指定文件夹到ftp服务器上
//@param folderName 本地要上传的文件夹全路径
//@param ftpPath FTP上对于根目录的路径
public String uploadFolder(String folderName, String ftpPath) throws
Exception {
if (isLogin) {
String strMsg = "";
try {
File file = new File(folderName);

if (file.isDirectory()) {
ftpClient.chdir("\\");
ftpClient.setType(FTPTransferType.BINARY);

if (checkFolderIsExist(ftpPath)) {
ftpClient.chdir(ftpPath);
} else {
createFolder(ftpPath);
}

if (!checkFolderIsExist(file.getName())) {
ftpClient.mkdir(file.getName());
}

ftpClient.chdir(file.getName());

ftpPath = ftpPath + "\\" + file.getName();
File[] files = file.listFiles();

for (int i = 0; i < files.length; i++) {
// System.out.println("==============================");
// System.out.println("ftpPath:"+ftpPath);
// System.out.println("files["+i+"]:"+files[i].getPath());
// System.out.println("==============================");

if (files[i].isDirectory()) {
uploadFolder(files[i].getPath(), ftpPath);
} else {
if (files[i].isFile()) {
try {
//===========================方法一开始================================
//ftpClient.chdir("\\");
//ftpClient.chdir(ftpPath);
//ftpClient.put(files[i].getPath(),files[i].getName());
//===========================方法一结束=================================
//
//===========================方法二开始================================
uploadFile(files[i].getPath(), ftpPath);
//===========================方法二结束================================
} catch (Exception ee) {
strMsg += "upload file<<：" +
files[i].getPath() +
">> error！Message:" + ee.getMessage() +
"\r\n";
}
}
}
}
if (!strMsg.equals("")) {
throw new Exception(strMsg);
}
} else {
System.out.println("file:" + file.getName());
throw new Exception(folderName + " is not a folder'name!");
}
} catch (Exception e) {
strMsg += e.getMessage() + "\r\n";
}
return strMsg;
} else {
throw new Exception("you didnot login remote ftp server!");
}
}
哪位大侠帮忙解决下？
