Screen scraping a mainframe screen in java?

I am new to programming world, and in my project I need to scre开发者_运维问答en scrape a mainframe screen using attachmate? Can anyone tell me what exactly screen scraping is and how does it work?

Thanks in advance.

IBM used to offer a package that would allow TN3270 connections from straight Java. I can't remember the name of the package, but if you can find that, you wouldn't need Attachmate at all.

I believe you will need to make a macro or module with Visual Basic for Attachemate's Reflecitons product. Have your VB macro save the data somewhere and then your Java program can read it.
