Hi Malaka, I researched for the libraries that we can use for FTP/SFTP operations in addition to using Apache Commons VFS. I found out about some widely used libraries such as SSHJ [1] and JSch [2] and did a comparison among them. With the use of those findings I created a comparison on SSHJ, Apache Commons VFS and JSch and published on my blog [3].
Also, I have experience in JSch since I had previously worked on developing a SCP transport using JSch [4] [5]. I believe its ability to execute shell commands with the help of the library is a great feature in JSch. According to the comparison and my experiences, JSch looks like the best candidate among them and I hope to hear others' thoughts about this. Please share your recommendations and suggestions to get a better approach to this project.
