B4J Question Large file upload

[wl]

Hi,

I would like to be able to upload large files (such as movies of a few GB's) from one PC to a server using a B4J app on both sides.

What would be the best approach to do this ? I would guess through a network stream ? Any examples ?

Thanks

There are several methods. Unfortunately the best approach is http but it will not give you feedback on the process

I use ssh

SSHJ - ssh, scp, sftp for Java

This is a wrapper for: https://github.com/hierynomus/sshj Dependencies: #AdditionalJar: slf4j-api-1.7.25 #AdditionalJar: sshj-0.23.0 #AdditionalJar: eddsa-0.2.0 #AdditionalJar: bcprov-jdk15on-159 You can download this libraries from: slf4j-api-1.7.25...

This one will give you the bytes already uploaded so you can know how much is missing. Afaik ftp does the same.

The downside is that is in the OS level. So you will have to thighten your security a notch.

Unfortunately SSH is not an option, since there need pre-communication between server and client on which file(s) to upload etc (part of a sync application).

Not receiving feedback is not a big issue (I think), but I am afraid to take an approach where a very large file needs to be put in memory (as is with a HTTP(s) POST I believe ?)

What's wrong with using FTP?
