I'm trying to interface/connect with an IBM 3070 mainframe. I think it's written in COBOL and is called Rumba. The goal is to use java to automate certain tasks. Previously, someone had put together a small routine in Visual Basic using Emulator "3070". I don't know a lot about Visual Basic and would much rather code in Java.
Has anyone had this issue? I've searched Legacy libraries and that type of thing. However, is there an easier way?
