From the developer:
IBM’s Host On-Demand(HOD) software provides secure TN3270 terminal access and FTP(File Transfer Protocol) access to the ITS z/OS Mainframe. HOD is a java application that runs in the familiar environment of a web browser(Internet Explorer, Firefox, or Safari). It can also run in a non-browser mode, when the HOD Java Web Start client is used.
You may want to check out more software, such as PageScope Network Setup, Veeam FastSCP or CrossFTP Server, which might be similar to JWSHODN.
