I have one clarification in one of the tasks. It is required to interface to non java based web application for fetching mileage details. I have been thinking of screen scraping as an option. (i would say XQuery to extract data). Few websites say screen scraping is not a very elegant solution(i think they say screen scraping- rerminal emaulation).Iam planning to go ahead with screen scraping. What are your thoughts on this? Please let me know if there are any suggestions at the earliest possible. Thanks, Justin.
Thanks for your reply. I am now not so convinced with XQuery appraoch.It is used for data retreival. In the given scenario,if payment is made by award travel,mileage miles have to be debited if available. I feel for this update option,xquery may not be able to do update. can we not use session bean and dao to update mileage DB. Other option is to use web service,i think.Am i missing something. KIndly let me know. Thanks, Justin
Its possible to directly access the mileage DB and update or retrieve information, but remember that this will result in duplication of business logic that applies for retrieving and updating mileage information in the DB. But this is a perfectly fine approach and people have passed by using session bean to interact with the mileage DB. The only thing to remember: justify your decisions in the document.
I took SCEA Part I exactly 7 years back on 6th Aug, 2001, and on 6th Aug 2008 I took SCEA Part III and the same day I uploaded my assignment. So it took me almost 7 years to complete this certification
Wow it's very long duration I think really it is a big giant exam.
I feel 5 to 6 years experience working in Java should be enough to go ahead and take the SCEA exam. The preparation time completely depends upon your real work experience. If you have been designing / architecting systems for sometime then 2-3 weeks is enough for completing the assignment exam.
