Example of a CRUD grid using ExtJS and Spring Framework. Libs used in this project: Spring MVC Framework JSON lib ExtJS 3.1.1 - including RowEditor Plugin and Datadrop (ExtJS 3rd party plugin). Also, this example demonstrates how to save data from a excel file (take a look at http://github.com/loiane/extjs-grid-dragdrop-excel). Download this example and run it in a java app server.
