Which architecture would be best to use (request or component based)

We have to bring up report which has the following use-cases:

• Summarizing daily sales report which includes several charts thereby includes several Db server hits for bringing data for report page
• the UI components must be thin and easily customizable and usable.
• Updating several UI components based on search criteria
• Above all the report has to be shown in 4-5seconds.
• Also there has be security across the web application.
• Avoid the plumbing work asap.

I have gone through these links Java Component based vs Request based frameworks and Design Patterns web based applications

and confused which framework (component or request based framework ) suits the best.

Regards

Kris
