Need help in Architecture design

Hi All,
Can any one help in architecture design of one of my complex application.

Requirement :
In web based application, we need to generate Excel kind of report as HTML page
and after that we need to perform different kinds of operations like
--Add manual rows
-- Delete rows
-- Edit rows
-- adding comments based on each cell
-- viewing the added comments.
-- attaching the file based on each cell
-- viewing the attached file.
-- Collapsible functionality for some of rows

In the process of design we have come up with DB design and application frame work is Springs.
and for Web not yet finalized.
what is the best approach to implement this kind of UI?
--JSF?(keep in mind we need to Excel operations like above mentioned operations)
-- Any reporting tool which will provide editing functionality?

Please suggest me How can we do it? and what is the best technology for it? or is there any reporting tools?

Nothing to do with certification. Since you seem to be asking about tools that will work in the client's browser, I am moving this to the HTML forum. Note that most of your questions seem to be based around how to implement the UI - I suspect that the answers are more likely to revolve around client-side toolkits, not server side technologies.

Sounds like you better start learning advanced JavaScript techniques.

A library such as jQuery will be very helpful.
