I haven't understood some speficiations of SCEA exam - part II:

1) Will the new java application for travel agents replace
the 3270 screens or not? I mean...when the java application is ready the travel agents will go on using the 3270 screens to access to the legacy system to book all airfares?

2)Must the old legacy system (to book airfares) written in Cobol remain or I can replace it with a new j2ee architecture? In fact reading the "background" section and the "interview" it seems to be required to mantain ONLY the "Frequent Flyer Mileage System" (FFN)...am I right?

3)About the java application required for travel agents: what is useful for if I can't replace the web interface written in perl/html/cgi of the FFN? I ask this because to write a new java application to access the content of the FFM makes sense only if I can access to the Oracle database of FFM without going on using the old web interface. In fact if I give to the travel agents this new java application to access the Oracle DB of FFM for what reason they should go on using the old web interface? This would make sense only if my java application connects to the FFM using the old web interface: this means to use a screen-scraping solution but in this way I can't distinguish the data type being retrieved and this is what I absolutely need (for example to get the points redeemed)!!

Thanks everybody in advance!
