Hi
can any one give me some idea about webizing legacy applications using screen scraping techniques and what exactly HLLAPI is and how it can be used in screen scraping techniques. |

Hello,
If you implement some screen-scraping tool, you have added a gui front-end to a "regular" CICS/327x connection - which is probably already connecting via tcp/ip. Using a screen-scraper does not make your mainframe data or database web-enabled. It merely looks line a windows app rather than a 24x80 terminal.
One of the drawbacks of screen-scrapers is that in order to have the touch and feel of a win-based application, considerable overhead is often encountered.
If you describe what you really want to do (in a business sense rather than naming a technical altrenative), we may be able to offer suggestions. |

I want to use my mainframes as back end and want to use ASP or JSP screens in front end.
In a single line i want to access mainframe application using the java or VB..etc screens in place of cics screens.
one method is using MA series,application server,wweb server etc
there is another approach called screen scraping where you need not to touch your existing application and there will be middle layer which takes care of transferring the data |

Hello,
Yes, that is what i mentioned earlier. Crag mentioned a particular product (ther are several). To understand their particular implementation and use, you would need to review the material from those vendors.
If you are asking about writing your own screen scraper, you will probably not get many (if any) replies here. I believe no one here has written one of their own - it is not an every-day thing to do.
If it appears that i've not understood what you are asking, please clarify. |

embarking on your own to perform 3270 screen-scrape is probably not a good idea. As mentioned earlier, there are several industry proven products that can support your needs without changing existing 3270 cics programs. A couple of these work direct with BMS field names, (no screen scrape).
I would suggest:
Metastorm INc. "MIM FOR CICS"
Document Systems Inc. "COMQEXEC"
HostBridge Technology "HostBridge/XML"
Seagull Software "LegaSuite"
GT Software "IVORY"
