No,I can't do that. Bcos I would like to automate it. And I need some way to copy the public key to remote system without user intervention,I mean through java code. Asking the password for very first time is fine. But it should not ask every time I run the code. Yeah Thank you.

I implemented this using Jsch library with sftp channel. And for the very first time I'll be having the credentials of the remote system so I don't have any issues in login. And then as suggested by SamiLaine I copied my public key and my actual files the files which I actually wanted to copy to remote system. So for the next time while copying it didn't asked for any password.

That and JSCH is at a ridiculously low level relative to the scp command. I found a library that doesn't require this but it's bundled up and used as a command line tool. I looked through the source code and discovered how to use it without the command line.

Here's an example of uploading:. The biggest downside is that it's not in a maven repo that I could find. But, the ease of use is worth it to me. Here is an example to upload a file using JSch :.

I used to create those files manually: Open the WinSCP, give the credentials, open the desired path and upload the file.

Now I am in a situation to automate those things. Text will be entered in a text box or fetched from DB, it has to be written in a notepad file and should be uploaded to a WinSCP path.

I have implemented writing the file and it is working fine. What you call "WinSCP path" is actually a storage accessible via some file transfer protocol. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
