JDK FTP support

[David Hansmann]

Hi all,

I recently looked at openjdk.java.net and found that there doesn't seem 
to be a fixed plan to integrate full FTP support
(I'm referring to 
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4650689 ), so I 
wonder if you might be interested to use parts
of my FTP API located on http://j-ftp.sourceforge.net .

It  is part of a file transfer client which supports FTP using an API 
which I wrote and which has been tested for quite some time now,
SFTP (throug j2ssh or jsch), JCIFS (through JCIFS) and NFS (through Sun 
WebNFS) using
a common interface. Although the code may not be state-of-the art (no 
generics yet) the core classes are very small, easy to refactor, not 
very complicated in general and there are various of the features you 
mentioned already present (like one control connection for multiple 
downloads,
callbacks) and more.

It should for example be possible to to use the other APIs as plugins 
once this would be implemented so those other protocols could be used
by just placing the jars anywhere in the classpath.

I'd of course help with the developement, code cleanup, testing and 
support if anybody wants to give it a try - it would be really exiting to
contribute to the JDK especially because I started the project years ago 
because of the lack of a real (and OSS) java FTP API ;)

Greetings and thanks for your time,

David Hansmann

P.S.: If you want to take a look at the code you probably want to look 
at net/FtpConnection, the BasicConnection interface and the example code
in the doc/-directory.
