Hello,
I'm trying to use FtpServer in my code and I have what I think to be a
thread issue, but not sure.
That's why I ask for help, please, because I've not been able to find my
error !
When I run a "classic" client and server, everything work fine. The user
properties file is found,
with only one user called "paul", and server is correctly started with
this message :
Nb users :1
Users name :paul
298 [main] INFO org.apache.ftpserver.impl.DefaultFtpServer - FTP server
started
I suppose [main] means that server is running in main thread.
You can have a look at "classic" server code below.
When a connection is initiated from the client (see "classic" client
code below), here are messages
coming from server (as you can see everything is working fine) :
302734 [NioProcessor-1] INFO
org.apache.ftpserver.listener.nio.FtpLoggingFilter - CREATED
302740 [pool-3-thread-1] INFO

okay, need password for paul.

302987 [pool-3-thread-2] INFO
org.apache.ftpserver.listener.nio.FtpLoggingFilter - CLOSED
Now if I use the same kind of code (of course you have to trust me)
within a GUI interface (SWT-JFace), here what I get when server is started :
Nb users :1
Users name :paul
1741735 [Thread-0] INFO org.apache.ftpserver.impl.DefaultFtpServer - FTP
server started
What I can notice is that it seems we are not in main thread ???
And when a client tries to connect, here are messages coming from server :
1831252 [NioProcessor-3] INFO
org.apache.ftpserver.listener.nio.FtpLoggingFilter - CREATED
1831257 [pool-6-thread-1] INFO
org.apache.ftpserver.listener.nio.FtpLoggingFilter - OPENED
1831261 [pool-6-thread-1] INFO
org.apache.ftpserver.listener.nio.FtpLoggingFilter - CLOSED
and messages coming from client :
org.apache.commons.net.ftp.FTPConnectionClosedException: Connection
closed without indication.

Any help would be nice,
thanks a lot,
