Thank you for posting that example of a servlet-context listener-based launcher
for FTPServer within Spring. I appreciate it.
One question: I imported it into NetBeans, and made the few necessary changes
(substituting actual values for placeholders in properties, etc...). After
that, your example NetBeans project builds and runs. It Does start FtpServer
(does call its .start() method) when the webapplication is started in Glassfish.
However, it no longer accepts any FTP connections at all. I cannot get any FTP
client to successfully connect to it. So it can't be used. Maybe there is
another step I need to do which wasn't in the post? That's what I'm hoping,
because this example comes so close.
The problem is not failed login, because the USER and the PASS commands never
get issued to FTPServer. Instead, when the client, at the very first, tries to
get a connection to talk to the Server, the Server times out. THe client waits
and waits for a connection so it can send the USER command--but the connection
is never granted by FTPServer.
I already had an application which gave connections, allowed logins, uploads,
downloads, all FTP operations. It all worked perfectly in mine--but there was
one fundamental problem: it had to be kicked-off (the server started) by
calling a main() method. A no-no for a deployed, Spring-based web application.
In some cases, an impossibility. So my hope was that your post would solve
that prob. It does solve that problem--but unfortunately, no client can
connect any more. I've tested in SSL mode AND in basic, NON-SSL mode. Either
way, the server always times out before returning a connection to the client.
Do you know why this could be? Anyone else know? FtpServer Does start when the
webapp starts--but it no longer functions (allows connections).
