Hi Malaka, I have gone through the second link you provided [1] and extended my implementation [2] to JScape and Zehon libraries.(Already implemented FTP/SFTP with JSch and Apache commons vfx which supports only basic file upload and download). The two major drawbacks I found in JScape and Zehon are,
1.Not open source 2.JScape is not free (Free version is available for 1 month) So i think these two won't suitable for further implementation. I have also found a similar comparison [3] for mostly used FTP/SFTP libraries which i think will helpful in future implementations.It would be great if you can provide some additional materials on Java -nio-ftp-library [4]. Any comments on how to proceed? thanks [1] http://www.onkarjoshi.com/blog/126/which-library-to-use- for-ftp-sftp-ftps-file-transfer-in-java/ [2] https://github.com/hasithajayasundara/Simple-FTP-client-and-server [3] https://www.javacodegeeks.com/2015/08/commons-vfs-sshj-and-jsch-in-comparison.html [4] http://java-nio-ftp-library.soft112.com/ On Fri, Mar 17, 2017 at 10:56 AM, Hasitha Jayasundara < hasithajayasunda...@gmail.com> wrote: > Hi Malaka, > > Can you please provide me some additional materials to study > java-nio-ftp-library [1]. > > Thank you. > > [1] http://java-nio-ftp-library.soft112.com/ > > On Tue, Mar 14, 2017 at 3:31 PM, Hasitha Jayasundara < > hasithajayasunda...@gmail.com> wrote: > >> Hi Malaka, >> >> Thank you for the reply.The server part was an additional implementation >> I went through to get an understanding about client server programming in >> java using sockets.I'll study the links provided and let you know if >> there's any issue. >> >> Thanks >> >> On Tue, Mar 14, 2017 at 1:43 PM, Malaka Silva <mal...@wso2.com> wrote: >> >>> Hi Hasitha, >>> >>> Thank you for the explanation.
