[JSch-users] ChannelSftp usage from multiple threads

[Alon G. <alo...@gm...>]

Hello,

I'd like to perform multiple operations on an sftp server from multiple
threads simultaneously. All threads are servicing the same user connecting
to the same server sftp server.
Example:

- thread 1 performs a get() on file 1
- thread 2 performs a get() on file 2
- thread 3 performs a ls() on dir 3
- etc...

In my initial implementation I created a single session and a single
channel of type 'sftp', and shared it between all threads/requests. However
this doesn't seem to work - the InputStream used for get() can't be shared
across multiple requests and it gets closed when the second get() request
comes in.

What is the best practice for such a requirement? should each thread create
a new sftp channel and close it when done? do I also need a new session per
thread or can I still use a single user session and keep opening channels
from it on demand? is there a limit on how many sessions or channels can
(or should) be opened at the same time?

Appreciate your advice.
Alon.
