Screen scrape Bluezone terminal emulator - How to

Hi there,

I'm a newbie to Screen scraping. We have a 3270 Bluezone terminal emulator.
It uses a Win32 application to connect to the host (mainframe) using ActiveXControl/Java applet.
After establishing the connection we access various info. say reservation number .

Now, I'm trying to screen scrape this reservation # which is in the Bluezone terminal emulator into a Java program.
I've no clue how to do this. I did some POC on screen scraping HTML content. No proper direction
for screen scraping a Bluezone terminal emulator. I hope you guys could share some thoughts. Plz help

Thanks,
Sid
