Since today the new Showcase is available. The new Showcase is specially for the jqGrid based Grid Feature.
The Showcase is provided with the Full Hibernate Plugin for Struts2 and shows how easy it is to create a AJAX based paging table in Struts2 that is searchable, sortable and editable. Also it shows how to implement a Grid with an Subgrid.
Per default the Showcase is read-only to see how to edit, add and delete items, download the showcase and following the instructions.
