i will use something similar to 'screen scraper' to parse a request/response into html format.
If you assume the business logic invovled with FF system is dummy, you may wish to access it directly through DAO+stored procedure.

Hi Denis,
Thanks for your reply. I'm still not very much comfortable of using Screen Scraper here. Also, if I were to access FF database directly from my J2EE system then it is almost like re-writing CGI-PERL system.
Don't you think so?

another option is to enhance the FF system with web services support in addition to it's http/html support.

Hi Harish,
For communicating with CGI-Perl-Oracle, here we just attempt to integrate with external system. In my memory, 'Screen Scraper' seems to be a GUI Adapter for Mainframe gui. It may be related to specified vendor. However, just using pattern like 'Adapter', just try to wrap the external system and define the communication protocol. Define the rule as reasonable as you can. You need not dig in it too much. That everything will be all right.
that's all.

Tom, Thanks a lot for your reply. I also thought that 'Screen Scraper' is generally used to connect to Mainframe GUI. In your post, you said that define communication protocol to connect to CGI System. What protocol did you mean there? Is there any other way to connect?
Thanks

Hi Harish,
Here PROTOCOL means that the operation approach you communicates with the external system. For example, protocol TCP/IP, it is used to defined the format and something else for Computers' communication. Your procotol here may be the intension and format of communication of your J2EE system and the external system. In fact, I just did as I depicted. And it works well. I got an excellent marks.
