Subject [io] cannot upload more files with ftp
Date Mon, 03 Aug 2015 09:13:47 GMT
Dear all,
I have a problem with FTP file upload of more than 1 file, using
storeFileStream().
I can connect to an FTP client, and I can upload 1 file. When I try to
upload a second file, the server disconnects.
Using commons-net 3.3 FTPClient. Here is a minimal Java code:

|||||	public static void main(String[] args) throws IOException {
	    String host = "xxx";
	    String username = "xxx";
	    String password = "xxx";
	    String localFile1 = "xxx";
	    String localFile2 = "xxx";
	    String remoteFolder = "xxx";

	    FTPClient client = new FTPClient();
	    client.connect(host, 21);
	    client.login(username, password);
	    client.enterLocalPassiveMode();
	    client.setFileType(FTP.BINARY_FILE_TYPE);
	    client.changeWorkingDirectory(remoteFolder);

	    File localfile = new File(localFile1);
	    FTPFile[] files = client.listFiles(localfile.getName());
	    OutputStream os = client.storeFileStream(localfile.getName());
	    FileUtils.copyFile(localfile, os);
	    os.close();

	    localfile = new File(localFile2);
	    files = client.listFiles(localfile.getName());
	    System.out.println((files == null) ? null : files.length);
	    os = client.storeFileStream(localfile.getName());
	    FileUtils.copyFile(localfile, os);
	    os.close();

	}
|

An exception is thrown at the second storeFileStream():

Exception in thread "main" java.net.ConnectException: Connection refused

Do you have any idea?
