web application architecture -

-

we have existing app jsp based front end , java/dao based end connecting oracle db. enterprise level trading application.

recently our management gave directive use gwt have more modern , feel our front end pages. have migrated few existing pages gwt brand new development in gwt. gwt being used both rendering front end server side communications , ajax.

however, concerned embracing gwt client side architecture of rendering logic processing happens on client side.

  1. is concern justified?

  2. what other architectures recommend? spring mvc/webflow? else?

i'd start service architecture. keep processing in can swap uis in , out without rewriting end.

they can soap or rest. need not make them heavy.

best not depend on jsp or gwt processing. ever hope make available on ipad? it'd able without rewriting whole thing.

start coarse-grained services match use cases.
