Hi,
I want to use SFTP through webMethods and learnt through this forums that lot of people either use OpenSSH or jsch concept. I found this BW_Utilities package on net which uses the jsch from jcraft.com.
My question is that package free to use or do we need to have some kind of licencing to use it?

Thanks!
