将文件上传到服务器根目录

Question

I really have a problem while trying to upload a file into my servers root directory. I know that the File-Class cannot handle directorys like http://localhost:8080/rootdata .

Please do not tell me not to upload files to the root. I just want to know how to do that.

So is there a way bringing up my files in that root directory via java?

Thanks for any help

Use Apache's FTP library to browse and retrieve files from your servers filesystem. You can list out all the files in the root directory by using:

.listFiles()

Example:

String hostname = properties.getProperty("FTP_SERVER");
        String user = properties.getProperty("FTP_USER");
        String passwd = properties.getProperty("FTP_PASSWD");
        FTPClient client = new FTPClient();
        client.connect(hostname);
        client.login(user, passwd);
        String reply = client.getStatus();
        System.out.println(reply);
        client.enterRemotePassiveMode();
        client.changeWorkingDirectory("/");
        FTPFile[] files = client.listFiles();
