Description

Using the FTPClient object in commons net the way it is shown in the Javadoc results in a file that is 0 bytes on the remote host. When you get to the storeFile(..) method, it waits for about 20 seconds before it returns the error message shown to System.out.

I've tried a number of different things

1. commons-net version 3.0.1 (supposedly had the bug fix for this, but didn't work for me)
2. [boolean] storeFile (String, InputStream)
3. [OutputStream] storeFile (String)
4. commons-net version 1.4 (still no dice)
5. ftp.connect(server) and ftp.connect(server, 21)

Here's my code:

		boolean error = false;
		FTPClient ftp = new FTPClient();
		InputStream localStream = null;
		try {
			int reply;
			String server = "ftp.myserver.com";
			ftp.connect(server, 21);
			System.out.println("Connected to " + server + ".");
			System.out.print(ftp.getReplyString());

			// After connection attempt, you should check the reply code to
			// verify
			// success.
			reply = ftp.getReplyCode();

			if (!FTPReply.isPositiveCompletion(reply)) {
				ftp.disconnect();
				System.err.println("FTP server refused connection.");
				System.exit(1);
			}
			boolean wasSuccessful = ftp.login("user", "password");
			if (!wasSuccessful) {
				System.err.println("Login unsuccessful");
				System.exit(1);
			}
			
			System.out.println("login successful");
			String localPath="C:/projects/TEMP/uga.html";
			File localFile = new File(localPath);
			
			if (localFile.exists()) {
				localStream = new BufferedInputStream(new FileInputStream(localPath));
				wasSuccessful = ftp.storeFile("/offline3/uga.html", localStream);
				if (!wasSuccessful) {
					System.err.println("could not store file: " + localPath);
					System.exit(1);
				} else {
					System.out.println("Successfully saved file!");
				}
			}

			
			// transfer files
			ftp.logout();
		} catch (IOException e) {
			error = true;
			e.printStackTrace();
		} finally {
			if (ftp.isConnected()) {
				try {
					ftp.disconnect();
				} catch (IOException ioe) {
					// do nothing
				}
			}
			if (localStream != null) {
				try {
					localStream.close();
				} catch (IOException e) {
				}
			}
			System.exit(error ? 1 : 0);
	}

Here's my System.out:

More background:
FileZilla works on my machine
I've also tried the primitive Sun API, and it works perfectly:

		try {
			url = new URL("ftp://username:[e-mail]/offline3/uga.html;type=i");
			URLConnection urlc = url.openConnection();
			OutputStream os = urlc.getOutputStream(); // To upload
			
			String localPath = "C:/projects/TEMP/uga.html";
			InputStream bis = new BufferedInputStream(new FileInputStream(localPath));
			
			byte[] bstr = new byte[1024];
			while (bis.read(bstr) > 0) {
				os.write(bstr);				
			}
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
